Explicit data sets such as MovieLens work according to a ranking, for example a user gives one to five stars for a film. Implicit data like RetailRocket, for example, work with events for example user looks at the article, adds it to the shopping cart, pays for the article.
I am currently working with the neuMF model from TensorFlow.
This works with MovieLens. How do I put my implicit data set (RetailRocket) in the neuMF model ?
Do I have to convert the implicit data set to an explicit data set first? (So I give each event an assignment, for example addtoCart = 3, this would then be a ranking again)
If I don't need to convert it, how do I put these events (strings) into the model?
