报告题目: Latent Factor Model and Its Applications to Recommender System, Network Embedding and Beyond

报告人：王军辉　　教授  （ 香港城市大学）

报告内容：

Latent factor model has a long history in statistics and can be dated back to early 1900s. In this talk, we will talk about a number of modern applications of latent factor model, including recommender system, network embedding, as well as crowdsourcing. Interestingly, these applications are often referred to as the unstructured data, but all lead to similar matrix

type of data structure, and thus are particularly suitable for latent factor model. We will develop some exible yet powerful modeling strategies based on latent factor model, to tackle the cold-start issue in recommender system and community detection in networks. The developed models are supported by a variety of real applications as well as their asymptotic properties.
