Clinically-Grounded Counterfactual Reasoning for Medical Video Diagnosis

CVPR 2026

Clinical video diagnosis, in which physicians assess dynamic tissue responses across procedural stages, is critical for detecting diseases such as cervical and colorectal cancers. Recent spatiotemporal models map visual progressions directly to diagnostic outputs, yet overlook two hallmarks of exper

MiniTac: An Ultra-Compact 8 mm Vision-Based Tactile Sensor for Enhanced Palpation in Robot-Assisted Minimally Invasive Surgery

RA-L 2024

Robot-assisted minimally invasive surgery (RAMIS) provides substantial benefits over traditional open and laparoscopic methods. However, a significant limitation of robot-assisted minimally invasive surgery (RAMIS) is the surgeon's inability to palpate tissues, a crucial technique for examining tiss

SLR: Learning Quadruped Locomotion without Privileged Information

CoRL 2024poster

Traditional reinforcement learning control for quadruped robots often relies on privileged information, demanding meticulous selection and precise estimation, thereby imposing constraints on the development process. This work proposes a Self-learning Latent Representation (SLR) method, which achieve…

Attack on Practical Speaker Verification System Using Universal Adversarial Perturbations

ICASSP 2021accepted

In authentication scenarios, applications of practical speaker verification systems usually require a person to read a dynamic authentication text. Previous studies played an audio adversarial example as a digital signal to perform physical attacks, which would be easily rejected by audio replay det…

Speech Separation Using an Asynchronous Fully Recurrent Convolutional Neural Network

NeurIPS 2021poster

Recent advances in the design of neural network architectures, in particular those specialized in modeling sequences, have provided significant improvements in speech separation performance. In this work, we propose to use a bio-inspired architecture called Fully Recurrent Convolutional Neural Netwo…

Training Stronger Baselines for Learning to Optimize

NeurIPS 2020spotlight

Learning to optimize (L2O) is gaining increased attention because classical optimizers require laborious, problem-specific design and hyperparameter tuning. However, there are significant performance and practicality gaps between manually designed optimizers and existing L2O models. Specifically, l…
