  • Traditional recommendation systems rely on past usage data in order to generate new recommendations. [...] Key Method In particular, we use latent factor model for recommendation, and predict the latent factors from item’s descriptions using convolutional neural network when they cannot be obtained from usage data. Latent factors obtained by applying matrix factorization to the available usage data are used as ground truth to train the convolutional neural network.Expand Abstract
