GVI-Switch: A High-Precision GNSS-Visual-Inertial State Estimator for Indoor-Outdoor Environments

RA-L 2026

We propose a high-precision GNSS-visual-inertial state estimator named GVI-Switch, augmented with a loosely coupled Error State Kalman Filter (ESKF), to achieve stable six-degree-of-freedom (6-DoF) pose estimation under varying GNSS signal conditions. First, we developed a GNSS degradation detection

BadWindtunnel: Defending Backdoor in High-noise Simulated Training with Confidence Variance

ACL 2025finding

Current backdoor attack defenders in Natural Language Processing (NLP) typically involve data reduction or model pruning, risking losing crucial information. To address this challenge, we introduce a novel backdoor defender, i.e., BadWindtunnel, in which we build a high-noise simulated training envi…
