Dataset & DataLoader Design

Keep the recommended structure, number 1: use a BaseDataLoader that loads each modality, and a multimodal data loader that inherits from the BaseDataLoader. Then we incorporate an ID_mapper, which looks at patient IDs to build a dataframe (each column is a modality, each row a patient, the value is a tuple containing, first, a binary variable pointing out whether the subject has information in the specific modality and, for instance, the IDs for multiple cases of images taken). The dataframe can be expanded for more modalities, and the user can filter it regarding the modalities that are required. Finally, there is a validation function inside the DataLoader that makes sure that the patients have all the necessary information (for instance, determined in the metadata).
