As far as I know, lightfm is dealing with implicit interaction matrix, i.e., 0s and 1s. However it can also creates a weight matrix separately and get into the training....

Hi, This is not a question for this particular codebase, but I am just wondering how you achieve this. Recently I notice that if you are doing a collaborative filtering...

I looked through the sequence model, it looks like the model is trying to learn a user representation from the given sequence alone: `user_representation, _ = self._net.user_representation( sequence_var )` It...

Hello, I am relatively new to Pytorch. I have a question regarding the data in CPU/GPU, for example, in the source code here https://github.com/shenweichen/DeepCTR-Torch/blob/bb6064343e8d271843bbd7efb9e8f3ecbd5d42b3/deepctr_torch/models/basemodel.py#L310 In particular, `sparse_embedding_list = [embedding_dict[feat.embedding_name]( X[:,...
