Most existing approaches that integrate semantic concepts with 3D maps largely remain confined to the closed-set setting: they can only reason about a finite set of concepts, pre-defined at training time. Further, these maps can only be queried using class labels, or in recent work, using text prompts. -We address both these issues with ConceptFusion, a scene representation that is (1) fundamentally open-set, enabling reasoning beyond a closed set of concepts and (ii) inherently multimodal, enabling a diverse range of possible queries to the 3D map, from language, to images, to audio, to 3D geometry, all working in concert. ConceptFusion leverages the open-set capabilities of today's foundation models pre-trained on internet-scale data to reason about concepts across modalities such as natural language, images, and audio. We demonstrate that pixel-aligned open-set features can be fused into 3D maps via traditional SLAM and multi-view fusion approaches. This enables effective zero-shot spatial reasoning, not needing any additional training or finetuning, and retains long-tailed concepts better than supervised approaches, outperforming them by more than 40 percent margin on 3D IoU. We extensively evaluate ConceptFusion on a number of real-world datasets, simulated home environments, a real-world tabletop manipulation task, and an autonomous driving platform. We showcase new avenues for blending foundation models with 3D open-set multimodal mapping. - }, - -} - -@inproceedings{quadsoccer, - author = {Yandong Ji and Zhongyu Li* and Yinan Sun and Xue Bin Peng and Sergey Levine and Glen Berseth and Koushil Sreenath}, - title = {Hierarchical Reinforcement Learning for Precise Soccer Shooting Skills using a Quadrupedal Robot }, - booktitle = {Proc.

Moreover, we need to consider motion planning to shoot the hard-to-model deformable ball rolling on the ground with uncertain friction to a desired location. In this paper, we propose a hierarchical framework that leverages deep reinforcement learning to train (a) a robust motion control policy that can track arbitrary motions and (b) a planning policy to decide the desired kicking motion to shoot a soccer ball to a target.

This is a challenging problem that required previous approaches to use hand-designed descriptions of the new agent's morphology. Instead of hand-designing this description, we propose a data-driven method that learns a representation of morphology directly from the reinforcement learning objective. Ours is the first reinforcement learning algorithm that can train a policy to generalize to new agent morphologies without requiring a description of the agent's morphology in advance. We evaluate our approach on the standard benchmark for agent-agnostic control, and improve over the current state of the art in zero-shot generalization to new agents.

Incremental solvers are able to process incoming sensor data and produce maximum a posteriori (MAP) estimates in realtime by exploiting the natural sparsity within the graph for reasonable-sized problems. However, to enable truly longterm operation in prior unknown environments requires algorithms whose computation, memory, and bandwidth (in the case of distributed systems) requirements scale constantly with time and environment size. Some recent approaches have addressed this problem through a two-step process - first the variables selected for removal are marginalized which induces density, and then the result is sparsified to maintain computational efficiency. Previous literature generally addresses only one of these two components. In this work, we attempt to explicitly connect all of the aforementioned resource constraint requirements by considering the node removal and sparsification pipeline in its entirety. We formulate the node selection problem as a minimization problem over the penalty to be paid in the resulting sparsification. As a result, we produce node subset selection strategies that are optimal in terms of minimizing the impact, in terms of Kullback-Liebler divergence (KLD), of approximating the dense distribution by a sparse one. We then show that one instantiation of this problem yields a computationally tractable formulation. Finally, we evaluate the method on standard datasets and show that the KLD is minimized as compared to other commonly-used heuristic node selection techniques.}, -} - -@inproceedings{mu2016iros, - title={Slam with objects using a nonparametric pose graph}, - author={Mu, Beipeng and Liu, Shih-Yuan and Paull, Liam and Leonard, John and How, Jonathan P}, - booktitle={IEEE/RSJ International Conference onnIntelligent Robots and Systems (IROS)}, - year={2016}, - month={Oct}, - image = {papers/mu2016iros.png}, - arxiv = {1704.05959}, - video = {https://www.youtube.com/watch?v=gOwMiFlj8KU}, - abstract = {Mapping and self-localization in unknown environments are fundamental capabilities in many robotic applications. These tasks typically involve the identification of objects as unique features or landmarks, which requires the objects both to be detected and then assigned a unique identifier that can be maintained when viewed from different perspectives and in different images. The data association and simultaneous localization and mapping (SLAM) problems are, individually, well-studied in the literature. But these two problems are inherently tightly coupled, and that has not been well-addressed. Without accurate SLAM, possible data associations are combinatorial and become intractable easily. Without accurate data association, the error of SLAM algorithms diverge easily. This paper proposes a novel nonparametric pose graph that models data association and SLAM in a single framework. An algorithm is further introduced to alternate between inferring data association and performing SLAM. Experimental results show that our approach has the new capability of associating object detections and localizing objects at the same time, leading to significantly better performance on both the data association and SLAM problems than achieved by considering only one and ignoring imperfections in the other.}, -} - -@inproceedings{paull2017duckietown, - title={Duckietown: an open, inexpensive and flexible platform for autonomy education and research}, - author={Paull, Liam and Tani, Jacopo and Ahn, Heejin and Alonso-Mora, Javier and Carlone, Luca and Cap, Michal and Chen, Yu Fan and Choi, Changhyun and Dusek, Jeff and Fang, Yajun and others}, - booktitle={IEEE International Conference on Robotics and Automation (ICRA)}, - pages={1497--1504}, - year={2017}, - month={May}, - image = {papers/paull2017duckietown.png}, - arxiv = {http://www.mit.edu/~hangzhao/papers/duckietown.pdf}, - abstract = {Duckietown is an open, inexpensive and flexible platform for autonomy education and research.

In this work we propose an efficient framework based on recursive neural networks and coreset data summarization to learn the transitions between an arbitrary number of controller modes that can have arbitrary complexity. Our approach allows us to efficiently gather annotation data from the large-scale datasets that are required to train such hybrid nonlinear systems to be safe under all operating conditions, favoring underexplored parts of the data.

The vast majority of the literature on this subject is focused on addressing path planning for area coverage under the assumption that the robot’s pose is known or that error is bounded. In this work, we remove this assumption and develop a completely probabilistic representation of coverage. We show that coverage is guaranteed as long as the robot pose estimates are consistent, a much milder assumption than zero or bounded error. After formally connecting robot sensor uncertainty with area coverage, we propose an adaptive sliding window filter pose estimator that provides a close approximation to the full maximum a posteriori estimate with a computation cost that is bounded over time. Subsequently, an adaptive planning strategy is presented that automatically exploits conditions of low vehicle uncertainty to more efficiently cover an area. We further extend this approach to the multi-robot case where robots can communicate through a (possibly faulty and low-bandwidth) channel and make relative measurements of one another. In this case, area coverage is achieved more quickly since the uncertainty over the robots’ trajectories is reduced. We apply the framework to the scenario of mapping an area of seabed with an autonomous underwater vehicle. Experimental results support the claim that our method achieves guaranteed complete coverage notwithstanding poor navigational sensors and that resulting path lengths required to cover the entire area are shortest using the proposed cooperative and adaptive approach.}, -} - -@inproceedings{ort2018icra, - title={Autonomous Vehicle Navigation in Rural Environments without Detailed Prior Maps}, - author={Ort, Teddy and Paull, Liam and Rus, Daniela}, - booktitle={IEEE International Conference on Robotics and Automation (ICRA)}, - year={2018}, - month={May}, - image = {papers/ort2018icra.png}, - arxiv = {https://toyota.csail.mit.edu/sites/default/files/documents/papers/ICRA2018_AutonomousVehicleNavigationRuralEnvironment.pdf}, - abstract = {State-of-the-art autonomous driving systems rely heavily on detailed and highly accurate prior maps. However, outside of small urban areas, it is very challenging to build, store, and transmit detailed maps since the spatial scales are so large. Furthermore, maintaining detailed maps of large rural areas can be impracticable due to the rapid rate at which these environments can change. This is a significant limitation for the widespread applicability of autonomous driving technology, which has the potential for an incredibly positive societal impact. In this paper, we address the problem of autonomous navigation in rural environments through a novel mapless driving framework that combines sparse topological maps for global navigation with a sensor-based perception system for local navigation. First, a local navigation goal within the sensor view of the vehicle is chosen as a waypoint leading towards the global goal. Next, the local perception system generates a feasible trajectory in the vehicle frame to reach the waypoint while abiding by the rules of the road for the segment being traversed. These trajectories are updated to remain in the local frame using the vehicle’s odometry and the associated uncertainty based on the least-squares residual and a recursive filtering approach, which allows the vehicle to navigate road networks reliably, and at high speed, without detailed prior maps. We demonstrate the performance of the system on a full-scale autonomous vehicle navigating in a challenging rural environment and benchmark the system on a large amount of collected data.}, -} - -@inproceedings{mai2018local, - title={Local Positioning System Using UWB Range Measurements for an Unmanned Blimp}, - author={Mai, Vincent and Kamel, Mina and Krebs, Matthias and Schaffner, Andreas and Meier, Daniel and Paull, Liam and Siegwart, Roland}, - journal={IEEE Robotics and Automation Letters}, - volume={3}, - number={4}, - pages={2971--2978}, - year={2018}, - month={October}, - image = {papers/mai2018blimp.png}, - arxiv = {https://ieeexplore.ieee.org/document/8392389}, - abstract = {Unmanned blimps are a safe and reliable alternative to conventional drones when flying above people.

We present two multiplicative extended Kalman filters using ultrawideband radio sensors and a gyroscope to address this challenge. One filter is updated using a dynamics model of the blimp, whereas the other uses a constant speed model.

In this work, we propose an unsupervised paradigm for deep visual odometry learning. We show that using a noisy teacher, which could be a standard VO pipeline, and by designing a loss term that enforces geometric consistency of the trajectory, we can train accurate deep models for VO that do not require ground-truth labels. We leverage geometry as a self-supervisory signal and propose "Composite Transformation Constraints (CTCs)", that automatically generate supervisory signals for training and enforce geometric consistency in the VO estimate. We also present a method of characterizing the uncertainty in VO estimates thus obtained. To evaluate our VO pipeline, we present exhaustive ablation studies that demonstrate the efficacy of end-to-end, self-supervised methodologies to train deep models for monocular VO.

While these previous works support reactionary control, the representation learned is not usable for higher-level decision making required for autonomous navigation. This paper tackles the problem of learning a representation to predict a continuous control probability distribution, and thus steering control options and bounds for those options, which can be used for autonomous navigation. Each mode of the distribution encodes a possible macro-action that the system could execute at that instant, and the covariances of the modes place bounds on safe steering control values. Our approach has the added advantage of being trained on unlabeled data collected from inexpensive cameras. The deep neural network based algorithm generates a probability distribution over the space of steering angles, from which we leverage Variational Bayesian methods to extract a mixture model and compute the different possible actions in the environment. A bound, which the autonomous vehicle must respect in our parallel autonomy setting, is then computed for each of these actions. We evaluate our approach on a challenging dataset containing a wide variety of driving conditions, and show that our algorithm is capable of parameterizing Gaussian Mixture Models for possible actions, and extract steering bounds with a mean error of only 2 degrees. Additionally, we demonstrate our system working on a full scale autonomous vehicle and evaluate its ability to successful handle various different parallel autonomy situations.}, -} - -@inproceedings{bharadhwaj2018data, - title={A Data-Efficient Framework for Training and Sim-to-Real Transfer of Navigation Policies}, - author={Bharadhwaj, Homanga and Wang, Zihan and Bengio, Yoshua and Paull, Liam}, - booktitle={IEEE International Conference on Robotics and Automation (ICRA)}, - year={2019}, - month={May}, - arxiv = {1810.04871}, - image = {papers/homanga2019icra.png}, - abstract = {Learning effective visuomotor policies for robots purely from data is challenging, but also appealing since a learning-based system should not require manual tuning or calibration.

For this reason, it is desirable to be able to leverage \textit{simulation} and \textit{off-policy} data to the extent possible to train the robot. In this work, we introduce a robust framework that plans in simulation and transfers well to the real environment. Our model incorporates a gradient-descent based planning module, which, given the initial image and goal image, encodes the images to a lower dimensional latent state and plans a trajectory to reach the goal. The model, consisting of the encoder and planner modules, is trained through a meta-learning strategy in simulation first. We subsequently perform adversarial domain transfer on the encoder by using a bank of unlabelled but random images from the simulation and real environments to enable the encoder to map images from the real and simulated environments to a similarly distributed latent representation.

By maintaining the minimum hyperspherical energy during training, OPT can greatly improve the empirical generalization. Specifically, OPT fixes the randomly initialized weights of the neurons and learns an orthogonal transformation that applies to these neurons. We consider multiple ways to learn such an orthogonal transformation, including unrolling orthogonalization algorithms, applying orthogonal parameterization, and designing orthogonality-preserving gradient descent. For better scalability, we propose the stochastic OPT which performs orthogonal transformation stochastically for partial dimensions of neurons.

This problem has been overcome in the literature by some element of interactivity in the learning process - usually be somehow interleaving the execution of the learner and the teacher so that the teacher can demonstrate to the learner also how to recover from mistakes. In this paper, we consider the cases where the robot has the potential to do harm, and therefore safety must be imposed at every step in the learning process. We show that uncertainty is an appropriate measure of safety and that both the mixing of the policies and the data sampling procedure benefit from considering the uncertainty of both the learner and the teacher.

Recently, many subfields have emerged to understand how distributions of training tasks affect an RL agent's performance in unseen environments. While the field is extensive and ever-growing, recent research has underlined that variability among the different approaches is not as significant. We leverage this intuition to demonstrate how current methods for generalization in RL are specializations of a general framework. We obtain the fundamental aspects of this formulation by rebuilding a Markov Decision Process (MDP) from the ground up by resurfacing the game-theoretic framework of games against nature. The two-player game that arises from considering nature as a complete player in this formulation explains how existing methods rely on learned and randomized dynamics and initial state distributions. We develop this result further by drawing inspiration from mechanism design theory to introduce the role of a principal as a third player that can modify the payoff functions of the decision-making agent and nature. The games induced by playing against the principal extend our framework to explain how learned and randomized reward functions induce generalization in RL agents. The main contribution of our work is the complete description of the Generalization Games for Reinforcement Learning, a multiagent, multiplayer, game-theoretic formal approach to study generalization methods in RL. We offer a preliminary ablation experiment of the different components of the framework. We demonstrate that a more simplified composition of the objectives that we introduce for each player leads to comparable, and in some cases superior, zero-shot generalization compared to state-of-the-art methods, all while requiring almost two orders of magnitude fewer samples.}, - image={papers/generalization.png}, - year={2022} -} - -@inproceedings{bhatt2022f, - title={f-Cal: Aleatoric uncertainty quantification for robot perception via calibrated neural regression}, - author={Bhatt, Dhaivat and Mani, Kaustubh and Bansal, Dishank and Murthy, Krishna and Lee, Hanju and Paull, Liam}, - booktitle={2022 International Conference on Robotics and Automation (ICRA)}, - pages={6533--6539}, - year={2022}, - abstract={While modern deep neural networks are performant perception modules, performance (accuracy) alone is insufficient, particularly for safety-critical robotic applications such as self-driving vehicles. Robot autonomy stacks also require these otherwise blackbox models to produce reliable and calibrated measures of confidence on their predictions. Existing approaches estimate uncertainty from these neural network perception stacks by modifying network architectures, inference procedure, or loss functions. However, in general, these methods lack calibration, meaning that the predictive uncertainties do not faithfully represent the true underlying uncertainties (process noise). Our key insight is that calibration is only achieved by imposing constraints across multiple examples, such as those in a mini-batch; as opposed to existing approaches which only impose constraints per-sample, often leading to overconfident (thus miscalibrated) uncertainty estimates. By enforcing the distribution of outputs of a neural network to resemble a target distribution by minimizing an f -divergence, we obtain significantly better-calibrated models compared to prior approaches. Our approach, f-Cal, outperforms existing uncertainty calibration approaches on robot perception tasks such as object detection and monocular depth estimation over multiple real-world benchmarks.}, -

The question that is usually asked by the public is “when are self-driving cars going to be here?” On one side, entrusting the entire driving problem to an autonomous agent seems frustratingly daunting. On the other side, we have started to see real deployments of autonomous vehicles in limited capacities, so perhaps there is reason for hope. - -Autonomous driving advancements are typically evaluated along well-defined, but potentially myopic performance criteria. These metrics are reasonable in the sense that they do give us some quantitative measure that we can use for comparison. However, the true potential impact of this technology reaches far beyond these relatively simplistic measures. In this workshop we will take a broader perspective with respect to evaluating the progress that we have made towards making self-driving a reality. In the process, we will focus particularly on aspects of the integration of this technology that are rarely covered in technical papers on the subject. Specifically, we will focus on the following three objectives: - -The primary objective of this workshop is to stimulate a conversation between roboticists, who focus on the development and implementation of autonomy algorithms, and regulators, economists, psychologists, and lawyers who are experts on the broader impacts that self-driving vehicles will have on society. We feel that it is critical to foster a community of researchers and practitioners whose expertise extends beyond the algorithmic challenges of realizing self-driving vehicles. As roboticists, we are ill-equipped to understand the broad impacts of this technology in areas that include ethics, philosophy, psychology, regulations, legal policy, and risk, to name a few, and it is critical that technological development is guided by such impacts. We will achieve our objective by inviting speakers and panelists who are experts in these adjacent fields to stimulate a broader conversation around this technology. This objective would be considered achieved if participants take the new perspectives they were exposed to and consider them in their own specific field of interest. For roboticists, this means explicitly considering these broader issues in the development of their algorithms. A stretch goal would be to spawn research collaborations between roboticists and researchers from these adjacent fields. - - -Duckietown traditionally hosts AI-DO competitions biannually, with finals events held at machine learning and robotics conferences such as the International Conference on Robotics and Automation (ICRA) and the Neural Information Processing Systems (NeurIPS). - -AI-DO 6 will be in conjunction with NeurIPS 2021 and have three leagues: urban driving, advanced perception, and racing.

In this work, we empirically examine the effects of domain randomization on agent generalization. Our experiments show that domain randomization may lead to suboptimal, high-variance policies, which we attribute to the uniform sampling of environment parameters. We propose Active Domain Randomization, a novel algorithm that learns a parameter sampling strategy. Our method looks for the most informative environment variations within the given randomization ranges by leveraging the discrepancies of policy rollouts in randomized and reference environment instances. We find that training more frequently on these instances leads to better overall agent generalization. Our experiments across various physics-based simulated and real-robot tasks show that this enhancement leads to more robust, consistent policies. diff --git a/_projects/conceptfusion.md b/_projects/conceptfusion.md deleted file mode 100644 index ff5062c..0000000 --- a/_projects/conceptfusion.md +++ /dev/null @@ -1,42 +0,0 @@ ---- -title: "ConceptFusion: Open-set Multimodal 3D Mapping" - -# status: active - -notitle: false - -description: | - ConceptFusion builds open-set 3D maps that can be queried via text, click, image, or audio.

Most existing approaches that integrate semantic concepts with 3D maps largely remain confined to the closed-set setting: they can only reason about a finite set of concepts, pre-defined at training time. Further, these maps can only be queried using class labels, or in recent work, using text prompts. - -We address both these issues with ConceptFusion, a scene representation that is: (i) fundamentally open-set, enabling reasoning beyond a closed set of concepts (ii) inherently multi-modal, enabling a diverse range of possible queries to the 3D map, from language, to images, to audio, to 3D geometry, all working in concert. ConceptFusion leverages the open-set capabilities of today’s foundation models pre-trained on internet-scale data to reason about concepts across modalities such as natural language, images, and audio. We demonstrate that pixel-aligned open-set features can be fused into 3D maps via traditional SLAM and multi-view fusion approaches. This enables effective zero-shot spatial reasoning, not needing any additional training or finetuning, and retains long-tailed concepts better than supervised approaches, outperforming them by more than 40% margin on 3D IoU. We extensively evaluate ConceptFusion on a number of real-world datasets, simulated home environments, a real-world tabletop manipulation task, and an autonomous driving platform. We showcase new avenues for blending foundation models with 3D open-set multimodal mapping. diff --git a/_projects/ctcnet.md b/_projects/ctcnet.md deleted file mode 100644 index d361201..0000000 --- a/_projects/ctcnet.md +++ /dev/null @@ -1,20 +0,0 @@ ---- -title: Self-supervised visual odometry estimation - -description: | - A self-supervised deep network for visual odometry estimation from monocular imagery. - -people: - - krishna - - gunshi - - liam - -collaborators: - - ganesh - - madhav - -layout: project -link: "https://krrish94.github.io/CTCNet-release/" -image: /img/events/ctcnet.png -last-updated: 2019-01-01 ---- diff --git a/_projects/dal.md b/_projects/dal.md deleted file mode 100644 index 3a407d7..0000000 --- a/_projects/dal.md +++ /dev/null @@ -1,26 +0,0 @@ ---- -title: Deep Active Localization - -description: | - Learned active localization, implemented on "real" robots. - -people: - - sai - - dhaivat - - krishna - - vincent - - liam - -collaborators: - - keehong - -layout: project -last-updated: 2018-11-27 - -image: /img/papers/dal.jpg ---- - - -# Deep Active Localization - -Active localization is the problem of generating robot actions that allow it to maximally disambiguate its pose within a reference map. Traditional approaches to this use an information-theoretic criterion for action selection and hand-crafted perceptual models. In this work we propose an end-to-end differentiable method for learning to take informative actions that is trainable entirely in simulation and then transferable to real robot hardware with zero refinement. The system is composed of two modules: a convolutional neural network for perception, and a deep reinforcement learned planning module. We introduce a multi-scale approach to the learned perceptual model since the accuracy needed to perform action selection with reinforcement learning is much less than the accuracy needed for robot control. We demonstrate that the resulting system outperforms using the traditional approach for either perception or planning. We also demonstrate our approaches robustness to different map configurations and other nuisance parameters through the use of domain randomization in training.

Deep Reinforcement Learning (DRL) is a powerful tool to find an optimal policy for these processes, based on experience acquired during the training process. The training of a DRL agent requires many trajectories, which can be arduous and expensive to produce in the real world. Indeed, the real world is not parallelizable, may require human efforts to reset, and comes with risks for the robot and the environment. Gathering sufficient experience is therefore one of the most important challenges when applying DRL to robotics. *The objective of this project is to reduce the amount of samples necessary to train a DRL agent on a robot.* - -A diagram representing the generation process of the noisy target. - -DRL algorithms are complex processes. An important part of most model-free algorithms is learning the value function of a given state or state-action pair, i.e., the expected return given the current policy. To do so, deep supervised learning components are used, where the input is the state(-action), and the label is called the target. The target T is a noisy sample of the value. Often, it is computed using the reward r and the next state s' sampled from experience, the next action a' based on s' and the current policy, and the value Q of the next state-action pair which is bootstrapped from the current value estimator (this is the Temporal Difference target). The noise on the target negatively impacts the learning process: the networks learn from wrong data, which entails slower learning and instability. - -The key element in this project is the fact that the noise affecting in the target, i.e. its difference from the true and unique value function, is heteroscedastic. This means that the distribution it is sampled from changes for each input and training step. Sometimes, this distribution has a very low variance: the target is close to the value. Sometimes, on the other hand, the target is subject to a lot of noise and it does not contain useful information with respect to the value. Therefore, the value estimation task in DRL is a case of heteroscedastic regression. - -## Projects - -### Batch Inverse-Variance Weighting for Deep Heteroscedastic Regression - -Noisy labels slows the learning process in regression: the first part of this project was to prove that the effect of noisy labels can be mitigated given the hypothesis that we know the variance of the noise distribution of each label. How can we include this additional information for heteroscedastic regression? Intuitively, we shoud give more weight to the labels we trust more. In linear regression, the Gauss-Markov theorem shows that the optimal solution is to weigh each sample by the inverse of the variance of the label noise. We show that adapting inverse-variance weighting for gradient-based optimization methods allows to significantly improve the performance of the learning process. Our paper, [Batch Inverse-Variance Weighting: Deep Heteroscedastic Regression](https://arxiv.org/abs/2107.04497) (BIV), was presented at the [Uncertainty and Robustness in Deep Learning](https://sites.google.com/view/udlworkshop2021/home?authuser=0) workshop at ICML 2021. - -

- -### Inverse-Variance Reinforcement Learning - -See project page: https://montrealrobotics.ca/ivrl/ - -The second part of the project was to use this weighting scheme in a DRL setting. For this work, the challenge was to estimate the uncertainty of the target. A systematic analysis of the sources of uncertainty in the target generation process justifies the use of deep variance ensembles. These are used to estimate the variance due to the stochasticity of the environment and the policy, as well as the predictive uncertainty of the value prediction used to bootstrap the target. As the variance output by these deep ensembles is also the result of a training process, the uncertainty estimation is subject to complex dynamics. We show that the BIV weighting scheme is robust to changes of scale in the variance estimation. We show that combining BIV with deep variance ensembles in DRL algorithms such as DQN and SAC leads to significant improvements in the sample efficiency. This framework, called Inverse-Variance Reinforcement Learning (IV-RL), is presented in our [Sample Efficient Deep Reinforcement Learning via Uncertainty Estimation](https://openreview.net/forum?id=vrW3tvDfOJQ) submission to ICLR 2022. - - -

In particular, real-world navigation can require long-horizon planning using high-dimensional RGB images, which poses a substantial challenge for end-to-end learning-based approaches. Current semi-parametric methods instead achieve long-horizon navigation by combining learned modules with a topological memory of the environment, often represented as a graph over previously collected images. However, using these graphs in practice typically involves tuning a number of pruning heuristics to avoid spurious edges, limit runtime memory usage and allow reasonably fast graph queries. In this work, we present One-4-All (O4A), a method leveraging self-supervised and manifold learning to obtain a graph-free, end-to-end navigation pipeline in which the goal is specified as an image. Navigation is achieved by greedily minimizing a potential function defined continuously over the O4A latent space. Our system is trained offline on non-expert exploration sequences of RGB data and controls, and does not require any depth or pose measurements. We show that O4A can reach long-range goals in 8 simulated Gibson indoor environments, and further demonstrate successful real-world navigation using a Jackal UGV platform. diff --git a/_projects/taskography.md b/_projects/taskography.md deleted file mode 100644 index 41da054..0000000 --- a/_projects/taskography.md +++ /dev/null @@ -1,29 +0,0 @@ ---- -title: Taskography - Evaluating robot task planning over large 3D scene graphs - -notitle: false - -description: | - Taskography is the first large-scale robotic task planning benchmark over 3DSGs.

IROS 2021 Workshop on Evaluating the Broader Impacts of Self-Driving Cars

+ +

Self-driving cars have received significant attention in the last decade, and arguably have the potential to be the most impactful robotics application to date. The question that is usually asked by the public is “when are self-driving cars going to be here?” On one side, entrusting the entire driving problem to an autonomous agent seems frustratingly daunting. On the other side, we have started to see real deployments of autonomous vehicles in limited capacities, so perhaps there is reason for hope.

+ +

Autonomous driving advancements are typically evaluated along well-defined, but potentially myopic performance criteria. These metrics are reasonable in the sense that they do give us some quantitative measure that we can use for comparison. However, the true potential impact of this technology reaches far beyond these relatively simplistic measures. In this workshop we will take a broader perspective with respect to evaluating the progress that we have made towards making self-driving a reality. In the process, we will focus particularly on aspects of the integration of this technology that are rarely covered in technical papers on the subject. Specifically, we will focus on the following three objectives:

+ +

The primary objective of this workshop is to stimulate a conversation between roboticists, who focus on the development and implementation of autonomy algorithms, and regulators, economists, psychologists, and lawyers who are experts on the broader impacts that self-driving vehicles will have on society. We feel that it is critical to foster a community of researchers and practitioners whose expertise extends beyond the algorithmic challenges of realizing self-driving vehicles. As roboticists, we are ill-equipped to understand the broad impacts of this technology in areas that include ethics, philosophy, psychology, regulations, legal policy, and risk, to name a few, and it is critical that technological development is guided by such impacts. We will achieve our objective by inviting speakers and panelists who are experts in these adjacent fields to stimulate a broader conversation around this technology. This objective would be considered achieved if participants take the new perspectives they were exposed to and consider them in their own specific field of interest. For roboticists, this means explicitly considering these broader issues in the development of their algorithms. A stretch goal would be to spawn research collaborations between roboticists and researchers from these adjacent fields.

+ + One-4-All - Neural Potential Fields for Embodied Navigation + +

+ + +

An end-to-end fully parametric method for image-goal navigation that leverages self-supervised and manifold learning to replace a topological graph with a geodesic regressor. During navigation, the geodesic regressor is used as an attractor in a potential function defined in latent space, allowing to frame navigation as a minimization problem.

+ + f-Cal - Calibrated aleatoric uncertainty estimation from neural networks for robot perception + +

+ + +

f-Cal is calibration method proposed to calibrate probabilistic regression networks. Typical bayesian neural networks are shown to be overconfident in their predictions. To use the predictions for downstream tasks, reliable and calibrated uncertainity estimates are critical. f-Cal is a straightforward loss function, which can be employed to train any probabilistic neural regressor, and obtain calibrated uncertainty estimates.

Active Domain Randomization

+ +

Domain randomization is a popular technique for improving domain transfer, often used in a zero-shot setting when the target domain is unknown or cannot easily be used for training. In this work, we empirically examine the effects of domain randomization on agent generalization. Our experiments show that domain randomization may lead to suboptimal, high-variance policies, which we attribute to the uniform sampling of environment parameters. We propose Active Domain Randomization, a novel algorithm that learns a parameter sampling strategy. Our method looks for the most informative environment variations within the given randomization ranges by leveraging the discrepancies of policy rollouts in randomized and reference environment instances. We find that training more frequently on these instances leads to better overall agent generalization. Our experiments across various physics-based simulated and real-robot tasks show that this enhancement leads to more robust, consistent policies.

ConceptFusion: Open-set Multimodal 3D Mapping

+ +

Building 3D maps of the environment is central to robot navigation, planning, and interaction with objects in a scene. Most existing approaches that integrate semantic concepts with 3D maps largely remain confined to the closed-set setting: they can only reason about a finite set of concepts, pre-defined at training time. Further, these maps can only be queried using class labels, or in recent work, using text prompts.

+ +

We address both these issues with ConceptFusion, a scene representation that is: (i) fundamentally open-set, enabling reasoning beyond a closed set of concepts (ii) inherently multi-modal, enabling a diverse range of possible queries to the 3D map, from language, to images, to audio, to 3D geometry, all working in concert. ConceptFusion leverages the open-set capabilities of today’s foundation models pre-trained on internet-scale data to reason about concepts across modalities such as natural language, images, and audio. We demonstrate that pixel-aligned open-set features can be fused into 3D maps via traditional SLAM and multi-view fusion approaches. This enables effective zero-shot spatial reasoning, not needing any additional training or finetuning, and retains long-tailed concepts better than supervised approaches, outperforming them by more than 40% margin on 3D IoU. We extensively evaluate ConceptFusion on a number of real-world datasets, simulated home environments, a real-world tabletop manipulation task, and an autonomous driving platform. We showcase new avenues for blending foundation models with 3D open-set multimodal mapping.

Deep Active Localization

+ +

Active localization is the problem of generating robot actions that allow it to maximally disambiguate its pose within a reference map. Traditional approaches to this use an information-theoretic criterion for action selection and hand-crafted perceptual models. In this work we propose an end-to-end differentiable method for learning to take informative actions that is trainable entirely in simulation and then transferable to real robot hardware with zero refinement. The system is composed of two modules: a convolutional neural network for perception, and a deep reinforcement learned planning module. We introduce a multi-scale approach to the learned perceptual model since the accuracy needed to perform action selection with reinforcement learning is much less than the accuracy needed for robot control. We demonstrate that the resulting system outperforms using the traditional approach for either perception or planning. We also demonstrate our approaches robustness to different map configurations and other nuisance parameters through the use of domain randomization in training. The code is also compatible with the OpenAI gym framework, as well as the Gazebo simulator.

Inverse Variance Reinforcement Learning

+ +

Most robotics problems can be written as (Partially Observable) Markov Decision Processes (MDPs), with discrete or continuous observation and action spaces. Deep Reinforcement Learning (DRL) is a powerful tool to find an optimal policy for these processes, based on experience acquired during the training process. The training of a DRL agent requires many trajectories, which can be arduous and expensive to produce in the real world. Indeed, the real world is not parallelizable, may require human efforts to reset, and comes with risks for the robot and the environment. Gathering sufficient experience is therefore one of the most important challenges when applying DRL to robotics. The objective of this project is to reduce the amount of samples necessary to train a DRL agent on a robot.

+ +

+ +

DRL algorithms are complex processes. An important part of most model-free algorithms is learning the value function of a given state or state-action pair, i.e., the expected return given the current policy. To do so, deep supervised learning components are used, where the input is the state(-action), and the label is called the target. The target T is a noisy sample of the value. Often, it is computed using the reward r and the next state s’ sampled from experience, the next action a’ based on s’ and the current policy, and the value Q of the next state-action pair which is bootstrapped from the current value estimator (this is the Temporal Difference target). The noise on the target negatively impacts the learning process: the networks learn from wrong data, which entails slower learning and instability.

+ +

The key element in this project is the fact that the noise affecting in the target, i.e. its difference from the true and unique value function, is heteroscedastic. This means that the distribution it is sampled from changes for each input and training step. Sometimes, this distribution has a very low variance: the target is close to the value. Sometimes, on the other hand, the target is subject to a lot of noise and it does not contain useful information with respect to the value. Therefore, the value estimation task in DRL is a case of heteroscedastic regression.

Batch Inverse-Variance Weighting for Deep Heteroscedastic Regression

+ +

Noisy labels slows the learning process in regression: the first part of this project was to prove that the effect of noisy labels can be mitigated given the hypothesis that we know the variance of the noise distribution of each label. How can we include this additional information for heteroscedastic regression? Intuitively, we shoud give more weight to the labels we trust more. In linear regression, the Gauss-Markov theorem shows that the optimal solution is to weigh each sample by the inverse of the variance of the label noise. We show that adapting inverse-variance weighting for gradient-based optimization methods allows to significantly improve the performance of the learning process. Our paper, Batch Inverse-Variance Weighting: Deep Heteroscedastic Regression (BIV), was presented at the Uncertainty and Robustness in Deep Learning workshop at ICML 2021.

+ +

The second part of the project was to use this weighting scheme in a DRL setting. For this work, the challenge was to estimate the uncertainty of the target. A systematic analysis of the sources of uncertainty in the target generation process justifies the use of deep variance ensembles. These are used to estimate the variance due to the stochasticity of the environment and the policy, as well as the predictive uncertainty of the value prediction used to bootstrap the target. As the variance output by these deep ensembles is also the result of a training process, the uncertainty estimation is subject to complex dynamics. We show that the BIV weighting scheme is robust to changes of scale in the variance estimation. We show that combining BIV with deep variance ensembles in DRL algorithms such as DQN and SAC leads to significant improvements in the sample efficiency. This framework, called Inverse-Variance Reinforcement Learning (IV-RL), is presented in our Sample Efficient Deep Reinforcement Learning via Uncertainty Estimation submission to ICLR 2022.

One-4-All: Neural Potential Fields for Embodied Navigation

+ +

A fundamental task in robotics is to navigate between two locations. In particular, real-world navigation can require long-horizon planning using high-dimensional RGB images, which poses a substantial challenge for end-to-end learning-based approaches. Current semi-parametric methods instead achieve long-horizon navigation by combining learned modules with a topological memory of the environment, often represented as a graph over previously collected images. However, using these graphs in practice typically involves tuning a number of pruning heuristics to avoid spurious edges, limit runtime memory usage and allow reasonably fast graph queries. In this work, we present One-4-All (O4A), a method leveraging self-supervised and manifold learning to obtain a graph-free, end-to-end navigation pipeline in which the goal is specified as an image. Navigation is achieved by greedily minimizing a potential function defined continuously over the O4A latent space. Our system is trained offline on non-expert exploration sequences of RGB data and controls, and does not require any depth or pose measurements. We show that O4A can reach long-range goals in 8 simulated Gibson indoor environments, and further demonstrate successful real-world navigation using a Jackal UGV platform.

+ + ConceptFusion: Open-set Multimodal 3D Mapping + +

+ + +

ConceptFusion builds open-set 3D maps that can be queried via text, click, image, or audio. Given a series of RGB-D images, our system builds a 3D scene representation, that is inherently multimodal by leveraging foundation models such as CLIP, and therefore doesn’t require any additional training or finetuning.

+ + One-4-All - Neural Potential Fields for Embodied Navigation + +

+ + +

An end-to-end fully parametric method for image-goal navigation that leverages self-supervised and manifold learning to replace a topological graph with a geodesic regressor. During navigation, the geodesic regressor is used as an attractor in a potential function defined in latent space, allowing to frame navigation as a minimization problem.

+ + f-Cal - Calibrated aleatoric uncertainty estimation from neural networks for robot perception + +

+ + +

f-Cal is calibration method proposed to calibrate probabilistic regression networks. Typical bayesian neural networks are shown to be overconfident in their predictions. To use the predictions for downstream tasks, reliable and calibrated uncertainity estimates are critical. f-Cal is a straightforward loss function, which can be employed to train any probabilistic neural regressor, and obtain calibrated uncertainty estimates.

+ + Taskography - Evaluating robot task planning over large 3D scene graphs + +

+ + +

Taskography is the first large-scale robotic task planning benchmark over 3DSGs. While most benchmarking efforts in this area focus on vision-based planning, we systematically study symbolic planning, to decouple planning performance from visual representation learning.
