This workshop solicits the latest and significant contributions to developing and applying neural algorithms and theories to build intelligent recommender systems. Specifically, the workshop solicits papers (max 8 pages plus 2 extra pages) for peer review. The format of the submissions must be in line with the ICDM submissions, namely double-column in [IEEE conference format]. Furthermore, as in previous years, papers not accepted by the main conference will be automatically sent to a workshop selected by the authors when the papers were submitted to the main conference. By the unique ICDM tradition, all accepted workshop papers will be published in the dedicated ICDMW proceedings published by the IEEE Computer Society Press.

The workshop invites submissions on all topics of neural algorithms and theories for 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
-Theoretical analysis for recommender systems
-Data characteristics and complexity analysis in recommender systems
-Non-IID (non-independent and identical distribution) theories and practices for recommender systems
-AutoML for recommender systems
-Privacy issues in recommender systems
-Recommendations on small data sets
-Complex behavior modeling and analysis for recommender systems
-Psychology-driven user modeling for recommender systems
-Brain-inspired neural models for recommender systems
-Explainable recommender systems
-Adversarial recommender systems
-Multimodal recommender systems
-Rich-context recommender systems
-Heterogeneous relations modeling in recommender systems
-Various recommendation scenarios including but not limited to collaborative filtering, sequential recommendations, social recommendations, conversational recommendations, news recommendations, music recommendations, etc.
-The application of recommender systems in emerging domains including health care, Fintech, education, fashion industry, etc.
-Visualization in recommender systems
