v0.4.7: individual components can run independently and image treatment replicates that of Pytorch

The treatment of the image datasets in WideDeepDataset replicates that of Pytorch. In particular this source code:

if isinstance(pic, np.ndarray):
    # handle numpy array
    if pic.ndim == 2:
        pic = pic[:, :, None]

In addition, I have added the possibility of using each of the model components in isolation and independently. This is, one could now use the wide, deepdense (either DeepDense or DeepDenseResnet), deeptext and deepimage independently.

v0.4.6: Added `DeepDenseResnet` and increased code coverage

As suggested in issue #26 , I have added the possibility of the deepdense component that receives the embeddings from categorical columns and the continuous columns being a series of Dense ResNet blocks. This is all available via the class DeepDenseResnet and used identically than before:

deepdense = DeepDenseResnet(...)

model = WideDeep(wide=wide, deepdense=deepdense)

In addition, code coverage has increased to 91%

v0.4.5: Faster, memory efficient Wide component

Version 0.4.5 includes a new implementation of the Wide Linear component via an Embedding layer. Previous versions implemented this component using a Linear layer that received one hot encoded features. For large datasets, this was slow and was not memory efficient (See #18 ). Therefore, we decided to replace such implementation with an Embedding layer that receives label encoded features. Note that although the two implementations are equivalent, the latter is indeed faster and moreover significantly more memory efficient.

Also mentioning that the printed loss in the case of Regression is no longer RMSE but MSE. This is done for consistency with the metrics saved in the History callback.

NOTE: this does not change a thing in terms of how one would use the package. pytorch-widedeep can be used in the exact same way as previous versions. However, since the model components have changed, models generated with previous versions are not compatible with this version.
