How to Fine-tune PaliGemma for Object Detection Tasks

PaliGemma, released by Google in May 2024, is a Large Multimodal Model (LMM) capable of tasks like Visual Question Answering, object detection, and generating segmentation masks, with limited zero-shot capabilities. For optimal performance in specific domains such as medical imaging, fine-tuning is recommended. The text provides a detailed guide on fine-tuning PaliGemma to detect fractures in X-ray images using a dataset from Roboflow Universe, employing the smallest version of the model to conserve GPU resources in Google Colab. The process involves downloading a compatible dataset, ensuring correct formatting, setting up the model environment using the big_vision project, and downloading pre-trained weights and tokenizer from Kaggle. After fine-tuning the model using JAX, the guide demonstrates testing the model on a validation dataset, saving the weights, and deploying them using Roboflow Inference for application across various devices.
