LLMAR applies LLM reasoning with a self-correction reflection loop to generate semantic user motives for tuning-free recommendations, showing up to 54.6% nDCG@10 gains on a sparse industrial dataset over trained baselines.
Behavior-guided calibration converts co-user overlap into signed evidence applied only to multimodal recommender shortlists and yields consistent gains on Amazon Baby, Sports, and Electronics datasets.
H-MAPS uses a three-layered hierarchical memory to infer a reader's background and intent from implicit behaviors, generating profile-specific questions and on-device literature retrieval, as shown when NLP and HCI researchers receive different recommendations for the same paper.
