A Consistency-Improved LiDAR-Inertial Bundle Adjustment

RA-L 2026

Simultaneous Localization and Mapping (SLAM) using 3D LiDAR has emerged as a cornerstone for autonomous navigation in robotics. While feature-based SLAM systems have achieved impressive results by leveraging edge and planar structures, they often suffer from the inconsistent estimator associated wit

LLaVA-FA: Learning Fourier Approximation for Compressing Large Multimodal Models

ICLR 2026poster

Large multimodal models (LMMs) have achieved impressive performance on various vision-language tasks, but their substantial computational and memory costs hinder their practical deployment. Existing compression methods often decouple low-rank decomposition and quantization, leading to compounded rec…

Learning Global Hypothesis Space for Enhancing Synergistic Reasoning Chain

ICLR 2026poster

Chain-of-Thought (CoT) has emerged as an effective paradigm to enhance the reasoning ability of large language models (LLMs) in complex tasks. However, existing approaches still face two major challenges: (1) the lack of a global mechanism to integrate and interact across diverse reasoning hypothese…

FCIR: Rethink Aerial Image Super Resolution with Fourier Analysis

ICASSP 2023accepted

Recent years, deep-learning-based methods achieve remarkable improvements on the super-resolution (SR) task. However, recovering high-quality (HQ) texture from the low-quality (LQ) aerial image is still challenging due to the limited contextual modeling ability of current deep-learning methods as we…

Range-Aided Drift-Free Cooperative Localization and Consistent Reconstruction of Multi-Ground Robots

RA-L 2023

Fast and flexible dense reconstruction has been extensively studied due to its wide application. Considering the efficiency of multi-robot systems, cooperative reconstruction is gaining attention. Classic methods rely on inter-robot loop closures, which cannot work when there is no common area betwe
