ACE: Anisotropy-Controllable Embedding for LLM-enhanced Sequential Recommendation
Dongcheol Lee · Hye-young Kim · Jongwuk Lee
摘要
Recent advances in the LLM-as-Extractor paradigm leverage large language models (LLMs) to transfer semantically rich item embeddings into sequential recommendation (SR) backbones. However, LLM-generated embeddings often suffer from strong anisotropy. Most vectors are concentrated in similar direc...
