遗忘曲线的协同过滤推荐模型
Forgetting curve-based collaborative filtering recommendation model
摘要
Abstract
According to the time effect of historical information in a recommendation system, a forgetting curvebased collaborative filtering recommendation system was proposed. Based on components of the recommendation system, the model involved a time-effect quantization function into the calculation process of recommendations for unknown resources. Through a multi-procedure time-effect quantization model and the unit time mapping function, the model revealed a pattern of time-effect attenuating with customers interest for various resources, and obtained recommen-dations corresponding with forgetting characteristics of memory psychology. Experimental results demonstrate that this approach can reasonably solve time-effect quantization issues and perform better than current collaborative filte-ring recommendation systems.关键词
