A Temporal Item-Based Collaborative Filtering Approach

Item-based collaborative filtering is becoming the most promising approach in recommender systems. It can predict an active user’s interest for a target item based on his observed ratings. With the user’s interests changing during interacting with collaborative filtering, the issue of concept drift is becoming a main factor impacting the accuracy of recommendation. Aiming at the issue of concep...

Incremental Collaborative Filtering Considering Temporal Effects

Recommender systems require their recommendation algorithms to be accurate, scalable and should handle very sparse training data which keep changing over time. Inspired by ant colony optimization, we propose a novel collaborative filtering scheme: Ant Collaborative Filtering that enjoys those favorable characteristics above mentioned. With the mechanism of pheromone transmission between users a...

Temporal Collaborative Filtering with Bayesian Probabilistic Tensor Factorization

Real-world relational data are seldom stationary, yet traditional collaborative filtering algorithms generally rely on this assumption. Motivated by our sales prediction problem, we propose a factor-based algorithm that is able to take time into account. By introducing additional factors for time, we formalize this problem as a tensor factorization with a special constraint on the time dimensio...

Dynamic group recommendation with modified collaborative filtering and temporal factor

Group recommendation, which provides a group of users with information items, has become increasingly important in both the workspace and people’s social activities. Because users change their preferences or interests over time, the dynamics and diversity of group members is a challenging problem for group recommendation. In this article, we introduce a novel group recommendation method via fus...
