It models item-item similarities and makes predictions for a given user’s unknown ratings based on the ratings for items PROPOSEDMODEL •Employs the Restricted Boltzmann Machine (RBM) for collaborative filtering. Restricted Boltzmann Machine is a type of artificial neural network which is stochastic in nature. Second, RBM-CF estimates parameters by maximising log likelihood, while AutoRec directly min-imises RMSE, the canonical performance in rating predic-tion tasks. Restricted Boltz- mann Machine(RBM) model rivals the best collaborative filtering meth- ods, but it focuses on modeling the correlation between item ratings.
