VideoChat-M1: Collaborative Policy Planning for Video Understanding via Multi-Agent Reinforcement Learning

CVPR 2026

Most of the multi-agent video understanding frameworks adopt static and non-learnable tool invocation mechanisms, which limit the discovery of diverse clues essential for robust perception and reasoning regarding temporally or spatially complex videos. To address this challenge, we propose a novel M

Enhancing Multilingual Capabilities of Large Language Models through Self-Distillation from Resource-Rich Languages

ACL 2024long

While large language models (LLMs) have been pre-trained on multilingual corpora, their performance still lags behind in most languages compared to a few resource-rich languages. One common approach to mitigate this issue is to translate training data from resource-rich languages into other language…

Position: Towards Unified Alignment Between Agents, Humans, and Environment

ICML 2024poster

The rapid progress of foundation models has led to the prosperity of autonomous agents, which leverage the universal capabilities of foundation models to conduct reasoning, decision-making, and environmental interaction. However, the efficacy of agents remains limited when operating in intricate, re…

Positive and Negative Obstacles Detection Based on Dual-LiDAR in Field Environments

RA-L 2024

In the field of autonomous land vehicles (ALVs), environmental perception serves as the gateway for ALVs to acquire external information, directly determining the capabilities and intelligence level of autonomous driving. In the research of environmental perception technology for ALVs in field envir

An Extensible Plug-and-Play Method for Multi-Aspect Controllable Text Generation

ACL 2023long

Recently, multi-aspect controllable text generation that controls the generated text in multiple aspects (e.g., sentiment, topic, and keywords) has attracted increasing attention. Although methods based on parameter efficient tuning like prefix-tuning could achieve multi-aspect controlling in a plug…

Adversarial Generative Distance-Based Classifier for Robust Out-of-Domain Detection

ICASSP 2021accepted

Detecting out-of-domain (OOD) intents is critical in a task-oriented dialog system. Existing methods rely heavily on extensive manually labeled OOD samples and lack robustness. In this paper, we propose an efficient adversarial attack mechanism to augment hard OOD samples and design a novel generati…

Modeling Discriminative Representations for Out-of-Domain Detection with Supervised Contrastive Learning

ACL 2021short

Detecting Out-of-Domain (OOD) or unknown intents from user queries is essential in a task-oriented dialog system. A key challenge of OOD detection is to learn discriminative semantic features. Traditional cross-entropy loss only focuses on whether a sample is correctly classified, and does not expli…

A Deep Generative Distance-Based Classifier for Out-of-Domain Detection with Mahalanobis Space

COLING 2020main

Detecting out-of-domain (OOD) input intents is critical in the task-oriented dialog system. Different from most existing methods that rely heavily on manually labeled OOD samples, we focus on the unsupervised OOD detection scenario where there are no labeled OOD samples except for labeled in-domain…
