Researchers are exploring novel ways to enhance recommendation systems using large language models (LLMs). One approach, SCoRD, focuses on continual knowledge distillation to adapt retriever-reranker pipelines to evolving user interests without prohibitive costs. Another method, CoRRe, refines LLM-generated user interests by incorporating collaborative filtering signals post-LLM, achieving competitive performance without training. Additionally, a framework for managing the lifecycle of LLM-as-a-Judge systems is presented, exemplified by Netflix's use in evaluating recommendation explanations, and a method called 'Ask to Be Sure' quantifies interaction effectiveness by measuring uncertainty reduction in conversational recommender systems.

Recommendation systems increasingly adopt a two-stage pipeline, where an ID-based retriever retrieves candidates and an LLM-based reranker refines their rankings. To improve retrieval quality, reranker-to-retriever distillation is commonly used to transfer the reranker's knowledg…
Large language models (LLMs) have shown promise for training-free recommendation, but LLM-generated user interests are often too broad for fine-grained item retrieval. Existing methods incorporate collaborative filtering (CF) signals in a pre-LLM manner through candidate rerankin…
