DrAgent: Empowering Large Language Models as Medical Agents for Multi-hop Medical Reasoning

EMNLP 2025

Although large language models (LLMs) have demonstrated outperforming human experts in medical examinations, it remains challenging to adopt LLMs in real-world clinical decision-making that typically involves multi-hop medical reasoning. Common practices include prompting commercial LLMs and fine-tu

Information Transfer Across Clinical Tasks via Adaptive Parameter Optimisation

AISTATS 2025oral

This paper presents Adaptive Parameter Optimisation (APO), a novel framework for optimising shared models across multiple clinical tasks, addressing the challenges of balancing strict parameter sharing—often leading to task conflicts—and soft parameter sharing, which may limit effective cross-task i…

Generalizable Movement Intention Recognition with Multiple Heterogeneous EEG Datasets

ICRA 2023poster

Human movement intention recognition is important for human-robot interaction. Existing work based on motor imagery electroencephalogram (EEG) provides a non-invasive and portable solution for intention detection. However, the data-driven methods may suffer from the limited scale and diversity of th…

Egocentric Human Trajectory Forecasting With a Wearable Camera and Multi-Modal Fusion

RA-L 2022

In this letter, we address the problem of forecasting the trajectory of an egocentric camera wearer (ego-person) in crowded spaces. The trajectory forecasting ability learned from the data of different camera wearers walking around in the real world can be transferred to assist visually impaired peo

PoseSDF: Simultaneous 3D Human Shape Reconstruction and Gait Pose Estimation Using Signed Distance Functions

ICRA 2022poster

Vision-based 3D human pose estimation and shape reconstruction play important roles in robot-assisted healthcare monitoring and personal assistance. However, 3D data captured from a single viewpoint always encounter occlusions and exhibit substantial heterogeneity across different views, resulting i…

Tackling Long-Tailed Category Distribution under Domain Shifts

ECCV 2022poster

"Machine learning models fail to perform well on real-world applications when 1) the category distribution P(Y) of the training dataset suffers from long-tailed distribution and 2) the test data is drawn from different conditional distributions P(X|Y). Existing approaches cannot handle the scenario…

Dual Attention Guided Gaze Target Detection in the Wild

CVPR 2021poster

Gaze target detection aims to infer where each person in a scene is looking. Existing works focus on 2D gaze and 2D saliency, but fail to exploit 3D contexts. In this work, we propose a three-stage method to simulate the human gaze inference behavior in 3D space. In the first stage, we introduce a c…

Region-Aware Adaptive Instance Normalization for Image Harmonization

CVPR 2021poster

Image composition plays a common but important role in photo editing. To acquire photo-realistic composite images, one must adjust the appearance and visual style of the foreground to be compatible with the background. Existing deep learning methods for harmonizing composite images directly learn an…

Toward Fine-grained Facial Expression Manipulation

ECCV 2020poster

Facial expression manipulation aims at editing facial expression with a given condition. Previous methods edit an input image under the guidance of a discrete emotion label or absolute condition (e.g., facial action units) to possess the desired expression. However, these methods either suffer from…

3-D Canonical Pose Estimation and Abnormal Gait Recognition With a Single RGB-D Camera

RA-L 2019

Assistive robots play an important role in improving the quality of life of patients at home. Among all the monitoring tasks, gait disorders are prevalent in elderly and people with neurological conditions and this increases the risk of fall. Therefore, the development of mobile systems for gait mon
