About the Lecture:

Thanks to the rapid development of deep learning, the use of deep neural networks to construct low-dimensional representation vectors of users and products, combined with collaborative filtering and other ideas, has become a frontier hot issue in the current research on recommendation systems. This report will introduce the basic ideas of deep representation learning, and discuss how to use deep learning networks to represent multi-modal information of users and products, so as to portray users' fine-grained preferences.
