can l finetune this model directly on my MRI dataset ? because my dataset is so small ,can you give some advice?
thanks

Thank you for your question. Yes, you can fine-tune the model directly on your MRI dataset. However, if your dataset is small, prolonged fine-tuning may lead to overfitting, where the model becomes too specialized on the MRI data. While the performance on the MRI test set could still be good, the model's performance on other tasks (like CT scans) might suffer significantly or even fail, depending on what you expect the model to achieve.

I just want to train a model for breast cancer MRI. However, I only have data of about 1,500 patients. My idea is to use multiple MRI training images to train the image encoder first, and then fine-tune the model with the breast cancer data. Or simply use the breast cancer MRI data to fine-tune the model. Could you give me some suggestions?

I think you can fine-tune on MRI data directly based on our trained model, there is no need to train the visual encoder first.

Can I directly use the script you provided to fine tune Lora？

Sure, please make sure your visual encoder and mm_projector are also trainable.

sorry ,I am a beginner .How can I train a visual encoder and mm_projector on my small dataset? Fine tune M3D-clip? and How should I train this mm_projector? l have no idea. could you give me some advice?

You don't need to fine-tune M3D-CLIP, you can fine-tune the entire model directly. Under lora fine-tuning, the visual encoder and mm_projector are trained by default, here. I think you can directly fine-tue your model following here.
