the 'WideDeepDatasetFolder' runs. Now I need to clean the code and code the corresponding trainer. unit test...etc

Added update method to the LabelEncoder util. Needs more testing and then bring it to a Batch TabPreprocessor

Mostly copied and pasted the torchvision dataset foder module that will be implemented here for all, image, text and tabular (hopefully)

Flash attention

Added a example of flash and linear attention. Fix some small bugs in one example. Adjusted all new functionality to GPU usage

test passed. Need to increase a bit test coverage for the tabtransformer and attention_layers, and review the docs

implemented linear and 'standard' attention in a functional way so they are available via parameters passed to the main multi head attention class

Added linear attention from the paper 'Transformers are RNNs: Fast Autoregressive Transformers with Linear Attention'. This now needs to be turned into an encoder and offer as an optional model

Wide deep recsys

Fixed a bug related to the padding idx and the fast ai transforms. Also adjusted the scripts to show how one can use the 'load_movielens100k' function in the library

added movielens dataset and tests

Added the notebooks to illustrate how to use the library to build recommendation algos. A couple of bugs to fix and ready to merge and publish

Added the 1st of two notebooks to illustrate the use of the library in the context of recommendation systems

Added scripts on how to use the library for recsys in response to issue #133. Also Added a simple/basic transformer model for the text component before integrating with HF. Also added the option of specify the dimension of the feed forward network

first step towards adding an example on how to reproduce a kaggle notebook (details in the code) with this library

Feature importance

Added a notebook to illustrate the use of feature importance. And also fixed a little bug related to the calling of the callbacks.

Makint it consistent with master so I don't have to rebase or anything similar. Also fixing bugs related to the other forms of training where I did not fix the restore weights functionality

Fix #175 early stopping and model checkpoint restoring weights.
