3D MeanFlow: One-Step Point Cloud Completion and Generation via Average-Velocity Transport

ICML 2026poster

Point cloud completion and generation are important across many 3D tasks, where both fidelity and sampling efficiency matter. Prevailing high-fidelity approaches rely on long sampling schedules, which incur substantial inference latency. Few-step alternatives typically use rectification or distillat…

A Novel Contrastive Diffusion Graph Convolutional Network for Few-Shot Skeleton-Based Action Recognition

ICASSP 2024accepted

Existing skeleton spatial-temporal models tend to deteriorate the positional distinguishability of skeleton joints and lead to inaccurate spatial matching and poor interpretability. This paper proposes a novel contrastive diffusion graph convolutional network (CD-GCN) for few-shot action recognition…

Incorporating Scene Graphs into Pre-trained Vision-Language Models for Multimodal Open-vocabulary Action Recognition

ICRA 2024poster

This paper presents Action-SGFA, a novel action feature alignment approach to learn unified joint embeddings across four action modalities incorporating scene graph (SG) comprehension. A new training paradigm for Action-SGFA is also devised to improve pre-trained VL models using datasets with SG ann…

Open-Vocabulary Skeleton Action Recognition with Diffusion Graph Convolutional Network and Pre-Trained Vision-Language Models

ICASSP 2024accepted

This study explores unsupervised open-vocabulary skeleton action recognition, aiming at addressing inaccurate spatial matching and poor interpretability of existing GCN models. We present Skeleton-DGCFA, an approach to make feature alignment (FA) of skeleton with image modalities based on a large pr…
