Recommendation Systems: Concepts, Techniques, and Applications

Abstract: As the number of online items significantly grows, it becomes

a difficult task for users to find those items on their own. Good matching

of users to suitable items is critical to enhance user satisfaction, which

highlights the importance of recommendation systems. The recommendation

systems analyze users’ past behavioral characteristics, predicting the

items with which a user would be truly satisfied. The approaches to

recommendation systems are classified into two categories: content based

and collaborative filtering (CF) based approaches. In this talk, we discuss

the concepts, techniques, and applications of recommendation systems. We

start with the concepts of recommendation systems, and introduce a variety of

their applications. Next, we describe machine learning techniques

applied in developing recommendation systems. Finally, we share the

state-of-the-art techniques developed in our laboratory recently, and show their

effectiveness in terms of user satisfaction.
