CaIRec: Calibrated Modality Imputation for Incomplete Multimodal Recommendation

Ruiyu Liu, Xiaohao Liu, Miaomiao Cai +2

Real-world multimodal recommender systems often face incomplete modality observations, where items lack images, text, or other content features. Such incompleteness weakens item re…

ForecastAgentSearch: Towards a Multi-Expert Agent Search System for Geopolitical Event Forecasting

Miaomiao Cai, He Chang, Yunshan Ma +1

Geopolitical event forecasting is a challenging task, as it requires understanding complex regional contexts, dynamic event signals, and uncertain future outcomes. Recent advances…

Dynamic Spectral Denoising with Global-Context Attention for Multi-Behavior Recommendation

Miaomiao Cai, Yunshan Ma, Fangqi Zhu +5

Multi-behavior recommendation improves target-behavior prediction by exploiting heterogeneous auxiliary feedback (e.g., view, collect, and cart), yet its robustness is undermined b…

Dual-Diffusional Generative Fashion Recommendation

Mingzhe Yu, Lei Wu, Qianru Sun +1

Personalized generative recommender systems have emerged as a promising solution for fashion recommendation. However, existing methods primarily rely on implicit visual embeddings…

Scattered Hypothesis Generation for Open-Ended Event Forecasting

He Chang, Zhulin Tao, Lifang Yang +2

Despite the importance of open-ended event forecasting for risk management, current LLM-based methods predominantly target only the most probable outcomes, neglecting the intrinsic…

Generalizable Multimodal Large Language Model Editing via Invariant Trajectory Learning

Jiajie Su, Haoyuan Wang, Xiaohua Feng +6

Knowledge editing emerges as a crucial technique for efficiently correcting incorrect or outdated knowledge in large language models (LLM). Existing editing methods rely on a rigid…

Potent but Stealthy: Rethink Profile Pollution against Sequential Recommendation via Bi-level Constrained Reinforcement Paradigm

Jiajie Su, Zihan Nan, Yunshan Ma +6

Sequential Recommenders, which exploit dynamic user intents through interaction sequences, is vulnerable to adversarial attacks. While existing attacks primarily rely on data poiso…

Frozen LVLMs for Micro-Video Recommendation: A Systematic Study of Feature Extraction and Fusion

Huatuan Sun, Yunshan Ma, Changguang Wu +3

Frozen Large Video Language Models (LVLMs) are increasingly employed in micro-video recommendation due to their strong multimodal understanding. However, their integration lacks sy…

An item is worth one token in Multimodal Large Language Models-based Sequential Recommendation

Qiyong Zhong, Jiajie Su, Ming Yang +3

Sequential recommendations (SR) predict users' future interactions based on their historical behavior. The rise of Large Language Models (LLMs) has brought powerful generative and…

Pctx: Tokenizing Personalized Context for Generative Recommendation

Qiyong Zhong, Jiajie Su, Yunshan Ma +2

Generative recommendation (GR) models tokenize each action into a few discrete tokens (called semantic IDs) and autoregressively generate the next tokens as predictions, showing ad…
