Routing Between Generative and Collaborative User Profiles: A Serving-Time Gate for Controllable Novelty

Milad Sabouri, Neeraj Sharma, Sardar Hamidian +1

Large language models (LLMs) enable rich semantic user profiles for recommendation, but such profiles are more expensive to generate and are not necessarily desirable to deploy uni…

When LLM-Inferred User Context Adds Value in Production Streaming Recommendation

Milad Sabouri, Neeraj Sharma, Sardar Hamidian +1

Contextual information in recommender systems is shifting from static, predefined variables toward latent representations inferred from behavior. Large language models support this…

From Time and Place to Preference: LLM-Driven Geo-Temporal Context in Recommendations

Yejin Kim, Shaghayegh Agah, Mayur Nankani +5

Most recommender systems treat timestamps as numeric or cyclical values, overlooking real-world context such as holidays, events, and seasonal patterns. We propose a scalable frame…
