[Feature Request] More detailed description on input data process for data using implicit feedback

[omgwenxx]

Is your feature request related to a problem? Please describe.
I want to compare a multimodal setting based on the repo Ducho meets Elliot. I created my embeddings using the Ducho framework. My dataset does not include ratings, just transactions. In the documentation, I only found the parameter binarize, which transforms explicit ratings to "implicit ones". So, I know, that the framework is able to handle implicit feedback, just not how to give it as input.

Describe the solution you'd like
I would like more details to how to use the framework with datasets with implicit feedback is input.

Describe alternatives you've considered
I looked for examples in the repo and documentation about how datasets should be structured on the doc site previously provided.

BR,
Gwen
