Transfer learning in collaborative filtering for sparsity reduction
TL;DR: This paper discovers the principle coordinates of both users and items in the auxiliary data matrices, and transfers them to the target domain in order to reduce the effect of data sparsity.
Proceedings ArticleDOI
Transfer learning to predict missing ratings via heterogeneous user feedbacks
TL;DR: This paper explores how to use the binary preference data expressed in the form of like/dislike to help reduce the impact of data sparsity of more expressive numerical ratings.
Proceedings ArticleDOI
Online evolutionary collaborative filtering
TL;DR: This paper extended the widely used neighborhood based algorithms by incorporating temporal information and developed an incremental algorithm for updating neighborhood similarities with new data.
Proceedings Article
Active transfer learning for cross-system recommendation
TL;DR: This paper proposes a framework to construct entity correspondence with limited budget by using active learning to facilitate knowledge transfer across recommender systems, and first iteratively select entities in the target system based on a proposed criterion to query their correspondences in the source system.
Proceedings Article
Transferring localization models over time
TL;DR: This work introduces a novel semi-supervised Hidden Markov Model (HMM) to transfer the learned model from one time period to another to reduce the calibration effort for the current time period.
