Abstract

We propose a novel hybrid recommender system method that treats missing data in
a principled manner and that uses amortized inference for fast predictions. We name
this method, the Partial Variational Autoencoder (p-VAE). P-VAE uses a novel
probabilistic generative model to handle varying numbers of user ratings in a principled way. Using the proposed amortized partial inference technique in p-VAEs,
learning and inference can be efficiently performed by minimizing the so-called
partial variational upper bound, without making ad-hoc assumptions on the values
of missing ratings. Empirical experiments on the MovieLens dataset demonstrate
the state-of-the-art performance of our method for movie recommendations.
