By Pin Zhang, Juhua Pu, Yongli Liu, Zhang Xiong
Issue Date:November 2008
pp. 69-72
Incremental approaches learn drifting user interests mainly from user feedbacks. Most of those existing approaches assume that data instances in user feedbacks are binary labeled. This paper presents a novel incremental learning approach that learns drifti...
