摘要
A recommendation system acts in anticipation of the needs of a user and proactively pushes recommendation of the right product to the right people at the right time without requiring a user to issue an explicit query to a search engine. To do this, it explicitly models and learns user preferences while interacting with users, continuously monitors time varying candidate items and user context, and recommend the most relevant items to a specific user when appropriate. In this talk, we will present our work on combining Bayesian statistical machine learning and economics theories to help the software agent decide what to recommend and when to recommend based on Bayesian hierarchical models. Experimental results in various applications (e-commerce, restaurants, etc.) will be presented and discussed.
