AgentSelect: Benchmark for Narrative Query-to-Agent Recommendation

ICML 2026poster

LLM agents are rapidly becoming the practical interface for task automation, yet the ecosystem lacks a principled way to \emph{choose} among an exploding space of deployable configurations. Existing LLM leaderboards and tool/agent benchmarks evaluate components in isolation and remain fragmented acr…

Answering Narrative-Driven Recommendation Queries via a Retrieve–Rank Paradigm and the OCG-Agent

EMNLP 2025

Narrative-driven recommendation queries are common in question-answering platforms, AI search engines, social forums, and some domain-specific vertical applications. Users typically submit free-form text requests for recommendations, e.g., “Any mind-bending thrillers like Shutter Island you’d recomm

From Commands to Prompts: LLM-based Semantic File System for AIOS

ICLR 2025poster

Large language models (LLMs) have demonstrated significant potential in the development of intelligent LLM-based agents. However, when users use these agent applications to perform file operations, their interaction with the file system still remains the traditional paradigm: reliant on manual navig…

Graph4MM: Weaving Multimodal Learning with Structural Information

ICML 2025poster

Real-world multimodal data usually exhibit complex structural relationships beyond traditional one-to-one mappings like image-caption pairs. Entities across modalities interact in intricate ways, with images and text forming diverse interconnections through contextual dependencies and co-references.…

Massive Values in Self-Attention Modules are the Key to Contextual Knowledge Understanding

ICML 2025poster

Large language models (LLMs) have achieved remarkable success in contextual knowledge understanding. In this paper, we show for the first time that these concentrated massive values consistently emerge in specific regions of attention queries (Q) and keys (K) while not having such patterns in values…

PersonaX: A Recommendation Agent-Oriented User Modeling Framework for Long Behavior Sequence

ACL 2025finding

User profile embedded in the prompt template of personalized recommendation agents play a crucial role in shaping their decision-making process. High-quality user profiles are essential for aligning agent behavior with real user interests. Typically, these profiles are constructed by leveraging LLMs…

SLMRec: Distilling Large Language Models into Small for Sequential Recommendation

ICLR 2025poster

Sequential Recommendation (SR) task involves predicting the next item a user is likely to interact with, given their past interactions. The SR models examine the sequence of a user's actions to discern more complex behavioral patterns and temporal dynamics. Recent research demonstrates the great i…

i$^2$VAE: Interest Information Augmentation with Variational Regularizers for Cross-Domain Sequential Recommendation

UAI 2025

Cross-Domain Sequential Recommendation (CDSR) leverages user behaviors across multiple domains to mitigate data sparsity and cold-start challenges in Single-Domain Sequential Recommendation. Existing methods primarily rely on shared users (overlapping users) to learn transferable interest representa

iAgent: LLM Agent as a Shield between User and Recommender Systems

ACL 2025finding

Traditional recommender systems usually take the user-platform paradigm, where users are directly exposed under the control of the platform’s recommendation algorithms. However, the defect of recommendation algorithms may put users in very vulnerable positions under this paradigm. First, many sophis…

Fine-Grained Dynamic Framework for Bias-Variance Joint Optimization on Data Missing Not at Random

NeurIPS 2024poster

In most practical applications such as recommendation systems, display advertising, and so forth, the collected data often contains missing values and those missing values are generally missing-not-at-random, which deteriorates the prediction performance of models. Some existing estimators and regul…

MHSCNET: A Multimodal Hierarchical Shot-Aware Convolutional Network for Video Summarization

ICASSP 2023accepted

Video summarization is an essential problem in signal processing, which intends to produce a concise summary of the original video. Existing video summarization approaches regard the task as a keyframe selection problem and generally construct the frame-wise representation by combining the long-rang…
