Personalized and Multi-View Representation for Federated Cold-Start Recommendation

Jaehyung Lim, Wonbin Kweon, Woojoo Kim +3

Federated recommendation (FedRec) enables personalized modeling without centralizing users' interaction histories, but most existing methods assume a fixed item pool and thus overl…

RA-VLA: Retrieval-Augmented VLA for Test-Time Adaptation

Sanghwan Jang, Minjin Jeon, Minsoo Kim +3

Vision-Language-Action (VLA) models provide a versatile foundation for general robotic manipulation, yet they exhibit significant brittleness when confronted with novel task distri…

From Overlooked to Explored: Recovering Item Relations via Mixture of Perspectives for Sequential Recommendation

Junyoung Kim, Wonbin Kweon, Woojoo Kim +3

Capturing user preference from a user's interaction sequence is the central challenge of Sequential Recommendation (SR). This preference intuitively emerges from inter-item relatio…

VLM2Rec: Resolving Modality Collapse in Vision-Language Model Embedders for Multimodal Sequential Recommendation

Junyoung Kim, Woojoo Kim, Wonbin Kweon +3

Sequential Recommendation (SR) in multimodal settings typically relies on small frozen pretrained encoders, which limits semantic capacity and prevents Collaborative Filtering (CF)…

Personalized Federated Recommendation With Knowledge Guidance

Jaehyung Lim, Wonbin Kweon, Woojoo Kim +3

Federated Recommendation (FedRec) has emerged as a key paradigm for building privacy-preserving recommender systems. However, existing FedRec models face a critical dilemma: memory…

Federated Continual Recommendation

Jaehyung Lim, Wonbin Kweon, Woojoo Kim +4

The increasing emphasis on privacy in recommendation systems has led to the adoption of Federated Learning (FL) as a privacy-preserving solution, enabling collaborative training wi…
