arXiv:2605.26717v1 Announce Type: cross Abstract: Adapting large language models (LLMs) for personalized recommendation requires aligning their general-purpose capabilities with user-specific preferences while effectively leveraging both behavioral and semantic signals. Existing approaches typically integrate these signals at either the input level (e.g., injecting behavioral embeddings into the token space) or the output level (e.g., contrastive alignment of separate encoders), suffering from distribution gaps or lack of end-to-end task supervision. In this work, we introduce L2Rec, which uni
The rapid advancement and integration of large language models into various applications necessitate specialized techniques to optimize their performance for specific tasks like personalized recommendation, addressing current limitations in leveraging behavioral and semantic signals.
Improving personalized recommendation through advanced LLM techniques directly enhances user experience and engagement, which is critical for e-commerce, content platforms, and other digital services, leading to increased revenue and retention.
New approaches like L2Rec provide more sophisticated methods for aligning LLMs with user preferences by bridging the gap between behavioral and semantic signals, potentially leading to more accurate and nuanced recommendations than existing methods.
