A naive baseline and submission demo for the Foundation Model Prompting for Medical Image Classification Challenge 2023 (MedFM).
Please check out master branch. Third party implementation of MedFMC baseline is supported! It is based on the MMPreTrain, with backbone of ViT-cls, ViT-eva02, ViT-dinov2, Swin-cls and ViT-clip.
More details could be found in its document. Thanks Ezra-Yu for this excellent work.
Install requirements by
$ conda install pytorch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 cudatoolkit=10.1 -c pytorch
$ pip install mmcls==0.25.0 openmim scipy scikit-learn ftfy regex tqdm
$ mim install mmcv-full==1.6.0We suggest you install PyTorch successfully first, then install OpenMMLab packages and their dependencies.
Moreover, you can use other Computer Vision or other foundation models such as EVA and CLIP.
The results of ChestDR, ColonPath and Endo in MedFMC dataset and their corresponding configs on each task are shown as below.
We utilize Visual Prompt Tuning method as the few-shot learning baseline, whose backbone is Swin Transformer. The results are shown as below:
| N Shot | Crop Size | Epoch | mAP | AUC | Config |
|---|---|---|---|---|---|
| 1 | 384x384 | 20 | 13.14 | 56.49 | config |
| 5 | 384x384 | 20 | 17.05 | 64.86 | config |
| 10 | 384x384 | 20 | 19.01 | 66.68 | config |
| N Shot | Crop Size | Epoch | Acc | AUC | Config |
|---|---|---|---|---|---|
| 1 | 384x384 | 20 | 77.60 | 84.69 | config |
| 5 | 384x384 | 20 | 89.29 | 96.07 | config |
| 10 | 384x384 | 20 | 91.21 | 97.14 | config |
| N Shot | Crop Size | Epoch | mAP | AUC | Config |
|---|---|---|---|---|---|
| 1 | 384x384 | 20 | 19.70 | 62.18 | config |
| 5 | 384x384 | 20 | 23.88 | 67.48 | config |
| 10 | 384x384 | 20 | 25.62 | 71.41 | config |
Noted that MedFMC mainly focuses on few-shot learning i.e., transfer learning task. Thus, fully supervised learning tasks below only use 20% training data to make corresponding comparisons.
| Backbone | Crop Size | Epoch | mAP | AUC | Config |
|---|---|---|---|---|---|
| DenseNet121 | 384x384 | 20 | 24.48 | 75.25 | config |
| EfficientNet-B5 | 384x384 | 20 | 29.08 | 77.21 | config |
| Swin-B | 384x384 | 20 | 31.07 | 78.56 | config |
| Backbone | Crop Size | Epoch | Acc | AUC | Config |
|---|---|---|---|---|---|
| DenseNet121 | 384x384 | 20 | 92.73 | 98.27 | config |

Noted that the .txt files includes data split information for fully supervised learning and few-shot learning tasks.
The public dataset is splitted to trainval.txt and test_WithLabel.txt, and trainval.txt is also splitted to train_20.txt and val_20.txt where 20 means the training data makes up 20% of trainval.txt.
And the test_WithoutLabel.txt of each dataset is validation set.
Corresponding .txt files are stored at ./data_backup/ folder, the few-shot learning data split files {dataset}_{N_shot}-shot_train/val_exp{N_exp}.txt could also be generated as below:
python tools/generate_few-shot_file.pyWhere N_shot is 1,5 and 10, respectively, the shot is of patient(i.e., 1-shot means images of certain one patient are all counted as one), not number of images.
The images in each dataset folder contains its images, which could be achieved from original dataset.
In this repository we provided many config files for fully supervised task (only uses 20% of original traning set, please check out the .txt files which split dataset)
and few-shot learning task.
The config files of fully supervised transfer learning task are stored at ./configs/densenet, ./configs/efficientnet, ./configs/vit-base and
./configs/swin_transformer folders, respectively. The config files of few-shot learning task are stored at ./configs/ablation_exp and ./configs/vit-b16_vpt folders.
For the training and testing, you can directly use commands below to train and test the model:
# you need to export path in terminal so the `custom_imports` in config would work
export PYTHONPATH=$PWD:$PYTHONPATH
# Training
# you can choose a config file like `configs/vit-b16_vpt/in21k-vitb16_vpt1_bs4_lr6e-4_1-shot_chest.py` to train its model
python tools/train.py $CONFIG
# Evaluation
# Endo and ChestDR utilize mAP as metric
python tools/test.py $CONFIG $CHECKPOINT --metrics mAP
python tools/test.py $CONFIG $CHECKPOINT --metrics AUC_multilabel
# Colon utilizes accuracy as metric
python tools/test.py $CONFIG $CHECKPOINT --metrics accuracy --metric-options topk=1
python tools/test.py $CONFIG $CHECKPOINT --metrics AUC_multiclass
The repository is built upon MMClassification/MMPretrain. More details could be found in its document.
