Adapting Large Language Models to Forecast in Frequency Domain

ICASSP 2025accepted

Large language models (LLMs) have recently been applied to time series forecasting to leverage their reasoning and pattern recognition capabilities. Compared to task-specific forecasting models, LLMs exhibit generalizability and a broad understanding of cross-domain knowledge. However, current LLM-b…

TreeReview: A Dynamic Tree of Questions Framework for Deep and Efficient LLM-based Scientific Peer Review

EMNLP 2025

While Large Language Models (LLMs) have shown significant potential in assisting peer review, current methods often struggle to generate thorough and insightful reviews while maintaining efficiency. In this paper, we propose TreeReview, a novel framework that models paper review as a hierarchical an

Unsupervised Learning of Facial Optical Flow via Occlusion-Aware Global-Local Matching

ICASSP 2024accepted

Estimating optical flow from facial videos is an essential preprocessing step for many applications. However, it is a challenging task as the facial videos contain rich expressions, large displacements, and complex occlusions. Obtaining the ground truth optical flow for facial videos is very difficu…

Range Guided Depth Refinement and Uncertainty-Aware Aggregation for View Synthesis

ICASSP 2021accepted

In this paper, we present a framework of view synthesis, including range guided depth refinement and uncertainty-aware aggregation based novel view synthesis. We first propose a novel depth refinement method to improve the quality and robustness of the depth map reconstruction. To that end, we use a…

Cross-Drone Binocular Coordination for Ground Moving Target Tracking in Occlusion-Rich Scenarios

RA-L 2020

How to work effectively under occlusion-rich environments remains a challenge for airborne vision-based ground target tracking, due to the natural limitation of monocular vision. Given this, a novel cross-drone binocular coordination approach, inspired by the efficient coordination of human eyes, is
