An Efficient Deep Learning Model for Recommender Systems

摘要

Recommending the best and optimal content to user is the essential part of digital space activities and online user interactions. For example, we like to know what items should be sent to a user, what promotion is the best one for a user, what web design would fit a specific user, what ad a user would be more susceptible to or what creative cloud package is more suitable to a specific user. In this work, we use deep learning (autoencoders) to create a new model for this purpose. The previous art includes using Autoencoders for numerical features only and we extend the application of autoencoders to non-numerical features. Our approach in coming up with recommendation is using "matrix completion" approach which is the most efficient and direct way of finding and evaluating content recommendation.
