An Ion Exchange Mechanism Inspired Story Ending Generator for Different Characters
Xinyu Jiang, Qi Zhang, Chongyang Shi +3
Story ending generation aims at generating reasonable endings for a given story context. Most existing studies in this area focus on generating coherent or diversified story ending…
Supervised Deep Hashing for High-dimensional and Heterogeneous Case-based Reasoning
Qi Zhang, Liang Hu, Chongyang Shi +2
Case-based Reasoning (CBR) on high-dimensional and heterogeneous data is a trending yet challenging and computationally expensive task in the real world. A promising approach is to…
Sequential/Session-based Recommendations: Challenges, Approaches, Applications and Opportunities
Shoujin Wang, Qi Zhang, Liang Hu +3
In recent years, sequential recommender systems (SRSs) and session-based recommender systems (SBRSs) have emerged as a new paradigm of RSs to capture users' short-term but dynamic…
