train_higher.py is the training script of our proposed MetaPhys.

train_txt.py is the training script for regular supervised training.

train_txt_ft.py is the training script for supervised training + fine-tuning.

higher_model.py is the implemnetation of TS-CAN.

rppg_dataset.py is the dataloader for MetaPhys.

data_generator.py is the dataloader for regular supervised training.

splitter.py is the code for spliting support and query sets.

MetaPhys's dataloading schema is based on pytorch-meta (https://github.com/tristandeleu/pytorch-meta), and our inner/outer loop optimizaton is based on higher (https://github.com/facebookresearch/higher).
