recommendation - anyone using it? user knn works but item knn does not seem to
I am not an expert in this area so please correct my understanding:
1. User CF provides recommended items for a user hence the query in the apply model would be the list of users. This seemed to work well.
2. Item CF using the item knn recommends items for an item hence the query inputs to the model would be items. However, the model expects user list as the query input.
Have I gotten it all wrong? Or is there a an issue in the model?
