Integrate image and tabular data for deep learning.

pip install image_tabular

This library utilizes fastai and pytorch to integrate image and tabular data for deep learning and train a joint model using the integrated data.

1. Please first prepare image and tabular data separately as fastai LabelLists, and then integrate them using the get_imagetabdatasets function as below:

integrate_train, integrate_valid, integrate_test = get_imagetabdatasets(image_data, tab_data)

2. The train, validation, and optional test datasets can then be combined in a DataBunch:

db = DataBunch.create(integrate_train, integrate_valid, integrate_test,
                      path=data_path, bs=bs)

3. Next, we create a joint model to train on both image and tabular data simultaneously:

integrate_model = CNNTabularModel(cnn_model,
                                  tabular_model,
                                  layers = [cnn_out_sz + tab_out_sz, 32],
                                  ps=0.2,
                                  out_sz=2).to(device)

4. Finally, we pack everying into a fastai learner and train the joint model:

learn = Learner(db, integrate_model)
learn.fit_one_cycle(10, 1e-4)

The following notebook puts everything together and shows how to use the library for the SIIM-ISIC Melanoma Classification competition on Kaggle:
