Nowadays, the renaissance of artificial intelligence (AI) has attracted huge attention from every corner of the world. On the one hand, deep learning algorithms and theories have nearly dominated AI development in almost all areas, e.g., natural language processing (NLP), computer vision (CV) and planning and have shown great promise. On the other hand, recommender systems (RS), as one of the most popular and important applications of AI, are being widely planted into our daily lives and have made a huge difference. Naturally, the combination of deep learning and recommender systems has been flourishing for years and has shown great potential. In practice, deep learning has nearly dominated the recommender system research in recent years. Many state-of-the-art recommender systems are built on deep learning models.

This Research Topic solicits the latest and significant contributions on developing and applying deep learning algorithms and theories for building intelligent recommender systems, including cutting-edge theories, foundations, and learning systems. As well as actionable tools and impactful case studies of deep learning based recommender systems. Those theories and algorithms that focus on the particular issues in recommender systems, including interaction, preference elicitation, privacy, trust, accountability, emotions/personality etc. are most welcome. Also, works that focus on emerging application domains of recommender systems, including service, health care, education, finance, entertainment, etc. are particularly welcome. All the submissions will go into a quick and high-quality peer-review process for fast publication.

The Research Topic invites submissions on all topics of theories, algorithms and applications for deep learning based recommender systems, including but not limited to:

-Deep neural model for recommender systems
-Shallow neural model for recommender systems
-Neural theories particularly for recommender systems
-Theoretical analysis of neural models for recommender systems
