[AAAI 2023 Oral] Tracking and Reconstructing Hand Object Interactions from Point Cloud Sequences in the Wild
In this work, we tackle the challenging task of jointly tracking hand object pose and reconstructing their shapes from depth point cloud sequences in the wild, given the initial poses at frame 0.

[ICLR 2023] Near-optimal Coresets for Robust Clustering
We consider robust clustering problems in Rd, specifically k-clustering problems (e.g., k-Median and k-Means with m outliers, where the cost for a given center set C⊂Rd aggregates the distances from C to all but the furthest m data points.

[STOC 2023] Streaming Euclidean Max-Cut: Dimension vs Data Reduction
We design the first streaming algorithms that use space poly(d), and are thus suitable for a high dimension d.

[ICRA 2023] RLAfford: End-to-end Affordance Learning for Robotic Manipulation
In this study, we take advantage of visual affordance by using the contact information generated during the RL training process to predict contact maps of interest.

[WINE 2022] Optimal Private Payoff Manipulation against Commitment in Extensive-form Games
We show that it is polynomial-time tractable for the follower to find the optimal way of misreporting his private payoff information. Our work completely resolves this follower's optimal manipulation problem on an extensive-form game tree.

[ECCV 2022] Domain Randomization-Enhanced Depth Simulation and Restoration for Perceiving and Grasping Specular and Transparent Objects
Experiments demonstrate that the proposed DREDS dataset bridges the sim-to-real domain gap such that, trained on DREDS, our SwinDRNet can seamlessly generalize to other real depth datasets, e.g. ClearGrasp, and outperform the competing methods on depth restoration with a real-time speed.

[ECCV 2022] Faster VoxelPose: Real-time 3D Human Pose Estimation by Orthographic Projection
We present Faster VoxelPose to address the challenge by re-projecting the feature volume to the three two-dimensional coordinate planes and estimating X, Y, Z coordinates from them separately.

[ECCV 2022] AdaAfford: Learning to Adapt Manipulation Affordance for 3D Articulated Objects via Few-shot Interactions
In this paper, we propose a novel framework, named AdaAfford, that learns to perform very few test-time interactions for quickly adapting the affordance priors to more accurate instance-specific posteriors.

[SIGGRAPH 2019] Learning Character-Agnostic Motion for Motion Retargeting in 2D
We demonstrate that our framework can be used to robustly extract human motion from videos, bypassing 3D reconstruction, and outperforming existing retargeting methods, when applied to videos in-the-wild.
