Collaborative Motion Planning for Multiple Tractor-Trailer Vehicles Based on Local Conflict Search and Priority Game Inheritance

RA-L 2025

This paper introduces a novel approach for efficiently planning collision-free optimal trajectories for multiple tractor-trailer vehicles (TTVs) in environments with dense obstacles. The approach employs a hierarchical planning strategy to generate the initial homotopy path: at the higher level, it

Fusion-OSR: Cross-Domain Contrastive Learning with Weibull Calibration for Time Series Open Set Recognition

ICASSP 2025accepted

In recent years, numerous Time Series Anomaly Detection methods have emerged, focusing primarily on detecting anomalies within time series, with limited work on open set recognition. In real-world scenarios, obtaining anomaly data is challenging. We can acquire a limited number of samples representi…

Robust 4D Radar-Aided Inertial Navigation for Aerial Vehicles

ICRA 2025

While LiDAR and cameras are becoming ubiquitous for unmanned aerial vehicles (UAVs) but can be ineffective in challenging environments, 4D millimeter-wave (MMW) radars that can provide robust 3D ranging and Doppler velocity measurements are less exploited for aerial navigation. In this paper, we dev

Differential Beamforming with Null Constraints for Spherical Microphone Arrays

ICASSP 2024accepted

Differential microphone arrays (DMAs) can measure both the acoustic pressure field and the differential acoustic pressure fields, which gives them great advantages in a wide range of applications for acoustic and speech signal acquisition. The core component of DMAs is the so-called differential bea…

An Improved Solution to the Frequency-Invariant Beamforming with Concentric Circular Microphone Arrays

ICASSP 2020accepted

Frequency-invariant beamforming with circular microphone arrays (CMAs) has drawn a significant amount of attention for its steering flexibility and high directivity. However, frequency-invariant beam-forming with CMAs often suffers from the so-called null problem, which is caused by the zeros of the…

Multisource Remote Sensing Data Classification Using Deep Hierarchical Random Walk Networks

ICASSP 2019accepted

Collaborative classification of hyperspectral imagery (HSI) and light detection and ranging (LiDAR) data is investigated using effective hierarchical random walk networks, denoted as HRWN. The proposed HRWN jointly optimizes dual-tunnel CNN, pixelwise affinity and seeds map via a novel random walk l…

Properties and Limits of the Minimum-norm Differential Beamformers with Circular Microphone Arrays

ICASSP 2019accepted

Small aperture circular microphone arrays (CMAs) have been widely used in many applications such as teleconferencing, smartspeakers, and robotics. A critical component of such arrays is the differential beamformer, which can achieve relatively high spatial gains with the same beampatterns at most fr…
