It is a challenge for Information-Centric Network (ICN) that how to maximize the utilization of network-embedded cache. On-path collaboration is an efficient way to reduce access latency and cache redundancy. All nodes on ICN routing path work together to achieve higher performance than individual cache, and lower collaboration overhead than regional collaborative cache. In this paper, we formulate...
Collaborative filtering algorithms, such as matrix factorization techniques, are recently gaining momentum due to their promising performance on recommender systems. However, most collaborative filtering algorithms suffer from data sparsity. Active learning algorithms are effective in reducing the sparsity problem for recommender systems by requesting users to give ratings to some items when they...
