TF-LLMER resolves optimization barriers in LLM-enhanced recommenders through embedding normalization and Rec-PCA that aligns semantic representations with collaborative co-occurrence graphs.
DUET uses a three-stage joint profile generator with RL feedback to create consistent user-item textual profiles that outperform independent generation in recommendation tasks.
S²GR adds stepwise thinking tokens with contrastive supervision on codebook clusters to balance computational focus and ground reasoning paths in generative recommendation.
BUMP trains profile generators via bidirectional ranking on in-batch interactions using GRPO and an LLM judge, matching supervised methods on LaMP without task labels.
MixRAGRec is a multi-agent KG-RAG framework with an MoE retrieval agent for query-specific granularity, a knowledge alignment agent, and a contrastive recommendation agent trained jointly via MMAPO.
ComeIR introduces dual-level Engram memory and memory-restoring prediction to reconstruct SID-token embeddings and restore token granularity in generative recommendation.
RRCM trains an LLM to dynamically retrieve from collaborative and meta memories using group relative policy optimization driven by final top-k recommendation quality.
ABPO combines group-relative policy optimization with anchored exposure correction and asymmetric feedback handling to enable effective continual updates for LLM recommenders under bandit feedback constraints.
Unsupervised LLM input rewriting for dialogue discourse parsing introduces more regressions than repairs and has a practical ceiling on error repair, necessitating rewritability prediction for effective use with frozen parsers.
