BiomedGPT

BiomedGPT is pre-trained and fine-tuned with multi-modal & multi-task biomedical datasets. Details of used datasets are shown in datasets.md. If you have any questions, feel free to contact us or post issues.

Checkpoints

We provid pretrained checkpoints of BiomedGPT (Dropbox), which can be put in the scripts/ folder for further development. For finetuned checkpoints, please refer to checkpoints.md.

Note:

We emphasize that BiomedGPT, including its files, code, and checkpoints, is strictly for academic research purposes. Commercial and clinical uses are strictly prohibited for three key reasons: First, BiomedGPT is based on the OFA framework, which carries a non-commercial license that we have inherited. Second, our model is not licensed for use in healthcare settings. Finally, we have not implemented sufficient security measures, and the current model cannot guarantee the accuracy required for medical diagnoses.

Installation

git clone https://github.com/taokz/BiomedGPT
conda env create -f biomedgpt.yml
python -m pip install pip==21.2.4
pip install fairseq

Implementation

We provide the preprocessing, pretraining, finetuning and inference scripts in the scripts/ folder. You can follow the directory setting below:

BiomedGPT/
├── checkpoints/
├── datasets/
│   ├── pretraining/
│   ├── finetuning/
│   └── ...
├── scripts/
│   ├── preprocess/
│   │   ├── pretraining/
│   │   └── finetuning/
│   ├── pretrain/
│   ├── vqa/
│   └── ...
└── ...

Pretraining

Please follow datasets.md to prepare pretraining datasets, which includes 4 TSV files: vision_language.tsv, text.tsv, image.tsv and detection.tsv in the directory of ./datasets/pretraining/.

cd scripts/pretrain
bash pretrain_tiny.sh

Feel free to modify the hyperparameters in the bash script for your requirements or ablation study.

Downstreams

We provide the run scripts of fine-tuning and inference. There will be log files during execution. Before fine-tuning or inference, please refer to

cd scripts/vqa
# for fine-tuning
bash train_vqa_rad_beam.sh
# for inference
bash evaluate_vqa_rad_beam.sh

cd scripts/caption
# for fine-tuning
bash train_peir_gross.sh
# for inference
bash evaluate_peir_gross.sh

cd scripts/text_sum
# for fine-tuning
bash train_meqsum.sh
# for inference
bash evaluate_meqsum.sh

cd scripts/mednli
# for fine-tuning
bash train_mednli.sh
# for inference
bash evaluate_mednli.sh

cd scripts/image_cls
# for fine-tuning: I provide a template, please set different hyparameters for each dataset in MedMNIST if required.
bash train_medmnist.sh 
# for inference: a template
bash evaluate_medmnist.sh
