DIFFERENTIABLE USER-ITEM CO-CLUSTERING

Abstract:

The present concepts relate to a differentiable user-item co-clustering ("DUICC") model for recommendation and co-clustering. Users' interaction with items (e.g., content) may be centered around information co-clusters--groups of items and users that exhibit common consumption behavior. The DUICC model may learn fine-grained co-cluster structures of items and users based on their interaction data. The DUICC model can then leverage the learned latent co-cluster structures to calculate preference stores of the items for a user. The top scoring items may be presented to the user as recommendations.
