Softwarized Attention-Based Context-Aware Group Recommendation Technology in Event-Based Industrial Cyber-Physical Systems

چکیده

Industrial cyber-physical systems are smart systems, which amalgamate the physical processes with computational capabilities to seamlessly capture, monitor and control entities scenarios in industrial environments. Among them, event-based (EICPSs), such as Meetup Plancast, have gained rapid developments. EICPSs provide event recommendation service for groups, alleviates information overload problem. However, existing group models focus on how aggregate preferences of members, failing model complex deep influence contexts groups. In this article, we propose an attention-based context-aware (ACGER) EICPSs. ACGER deep, nonlinear users, events through multilayer neural networks. Especially, a novel attention mechanism is designed enable weights users/groups change dynamically concerned. Considering that groups may completely different behavior patterns from acquire preference two perspectives: indirect direct preference. To obtain preference, method aggregating based mechanism. Compared predefined strategies, can flexibly adapt strategy according concerned by group. employ networks learn it group-event interactions. Furthermore, make full use rich user-event interactions EICPSs, integrate individual task into ACGER, enhances accuracy learning user embeddings embeddings. Extensive experiments three real datasets Douban show our significantly outperforms state-of-the-art models.

Similarity-Based Context-Aware Recommendation

Context-aware recommender systems (CARS) take context into consideration when modeling user preferences. There are two general ways to integrate context with recommendation: contextual filtering and contextual modeling. Currently, the most effective context-aware recommendation algorithms are based on a contextual modeling approach that estimate deviations in ratings across different contexts. ...
