RAGA Metric Calculator

This project implements a RAGA (Retrieval Augmented Generation Assessment) metric calculator using a combination of predefined adapters.

Features

• Calculate various RAGA metrics including Noise Sensitivity, Faithfulness, Answer Relevancy, and more.
• Extensible design with adapter pattern to easily add more metrics.
• Metric Learner for calculating unknown metrics using OpenAI's GPT model.
• FastAPI application for API-based interaction.

Installation

1. Clone this repository:

   git clone https://github.com/Jasshporwal/RAGA.git
   cd RAGA
   

2. Install the required dependencies:

   pip install -r requirements.txt
   

Usage

1. Start the FastAPI server:

   python main.py 
   

2. The API will be available at http://localhost:8000. You can use the /calculate_metrics endpoint to calculate metrics.

3. Example API request:

   POST /calculate_metrics
   {
     "metrics": ["Noise Sensitivity", "Faithfulness", "Answer Relevancy"],
     "ground_truth": "The Earth is round",
     "answer": "The Earth is spherical",
     "question": "What is the shape of the Earth?",
     "context": "The Earth is the third planet from the Sun and is approximately spherical in shape."
   }
   

Adding New Metrics

To add a new metric:

1. Create a new adapter class in adapter.py that inherits from MetricAdapter.
2. Implement the calculate method for the new adapter.
3. Add the new adapter to the adapters dictionary in the MetricCalculator class in calculator.py.

For metrics without a specific adapter, the system will use the MetricLearner to calculate them using the OpenAI GPT model.
