From Deep Additive Kernel Learning to Last-Layer Bayesian Neural Networks via Induced Prior Approximation

AISTATS 2025poster

With the strengths of both deep learning and kernel methods like Gaussian Processes (GPs), Deep Kernel Learning (DKL) has gained considerable attention in recent years. From the computational perspective, however, DKL becomes challenging when the input dimension of the GP layer is high. To address t…

Imitation-Enhanced Reinforcement Learning With Privileged Smooth Transition for Hexapod Locomotion

RA-L 2025

Deep reinforcement learning (DRL) methods have shown significant promise in controlling the movement of quadruped robots. However, for systems like hexapod robots, which feature a higher-dimensional action space, it remains challenging for an agent to devise an effective control strategy directly. C

MFMamba: A Multimodal Fusion State Space Model for Depression Recognition

ICASSP 2025accepted

Depression is a severe mental illness, and extracting emotional information from video-audio signals for multimodal depression recognition is a challenging problem. Recent methods use the self-attention (SA) mechanism from Transformers to capture the dynamic relationships between different modalitie…

Whole-Body Constrained Learning for Legged Locomotion via Hierarchical Optimization

RA-L 2025

Reinforcement learning (RL) has demonstrated impressive performance in legged locomotion over various challenging environments. However, due to the sim-to-real gap and lack of explainability, unconstrained RL policies deployed in the real world still suffer from inevitable safety issues, such as joi

Enhancing Cooperative Exploration and Planning: UAV-Legged Robot Synergy

RA-L 2024

Specialized robots, such as legged robots and unmanned aerial vehicles (UAVs), are commonly regarded as effective platforms for aiding in search and rescue (SAR) missions. However, existing approaches often decouple the tasks between UAVs and legged robots, for instance, using UAVs for mapping and l

Learning to Predict 3D Lane Shape and Camera Pose from a Single Image via Geometry Constraints

AAAI 2022technical

Detecting 3D lanes from the camera is a rising problem for autonomous vehicles. In this task, the correct camera pose is the key to generating accurate lanes, which can transform an image from perspective-view to the top-view. With this transformation, we can get rid of the perspective effects so th…

DeepVS: A Deep Learning Based Video Saliency Prediction Approach

ECCV 2018poster

In this paper, we propose a novel deep learning based video saliency prediction method, named DeepVS. Specifically, we establish a large-scale eye-tracking database of videos (LEDOV), which includes 32 subjects' fixations on 538 videos. We find from LEDOV that human attention is more likely to be at…
