Density-Driven Progressive Shape Formation for Swarm Robots in Dynamic Environments

RA-L 2026

This letter presents a novel density-based control framework for shape formation in swarm robotic systems, operating exclusively on local perception without requiring communication or identity recognition among robots and targets. Inspired by Smoothed Particle Hydrodynamics (SPH), each robot estimat

Emergence of Adaptive Collective Evasion Through Density-Based Interactions in Swarm Robotics

RA-L 2026

Collective evasion is critical in swarm robotics, enabling groups of simple robots to effectively elude external threats. Previous work on anti-predator behaviors relied on rigid evasion patterns coupled with velocity alignment, which lack adaptability when confronted with sustained and varied preda

Can Large Language Models Detect Errors in Long Chain-of-Thought Reasoning?

ACL 2025long

Recently, o1-like models have drawn significant attention, where these models produce the long Chain-of-Thought (CoT) reasoning steps to improve the reasoning abilities of existing Large Language Models (LLMs). In this paper, to understand the qualities of these long CoTs and measure the critique ab…

Chinese SimpleQA: A Chinese Factuality Evaluation for Large Language Models

ACL 2025long

New LLM benchmarks are important to align with the rapid development of Large Language Models (LLMs). In this work, we present Chinese SimpleQA, the first comprehensive Chinese benchmark to evaluate the factuality ability of LLMs to answer short questions, and Chinese SimpleQA mainly has five proper…

VC4VG: Optimizing Video Captions for Text-to-Video Generation

EMNLP 2025

Recent advances in text-to-video (T2V) generation highlight the critical role of high-quality video-text pairs in training models capable of producing coherent and instruction-aligned videos. However, strategies for optimizing video captions specifically for T2V training remain underexplored. In thi

ContPhy: Continuum Physical Concept Learning and Reasoning from Videos

ICML 2024poster

We introduce the Continuum Physical Dataset (ContPhy), a novel benchmark for assessing machine physical commonsense. ContPhy complements existing physical reasoning benchmarks by encompassing the inference of diverse physical properties, such as mass and density, across various scenarios and predict…

Emergence of Collective Behaviors for the Swarm Robotics Through Visual Attention-Based Selective Interaction

RA-L 2024

Plenty of local interaction mechanisms have been proposed to achieve collective behaviors in swarm robotics. However, these mechanisms require robots to explicitly obtain the velocity of their neighbors as the sensory input to make motion decisions. This further poses great challenges in real-world
