Towards Unifying Diffusion Models for Probabilistic Spatio-Temporal Graph Learning

no code implementations26 Oct 2023 Junfeng Hu, Xu Liu, Zhencheng Fan, Yuxuan Liang, Roger Zimmermann

Based on this proposal, we introduce Unified Spatio-Temporal Diffusion Models (USTD) to address the tasks uniformly within the uncertainty-aware diffusion framework.

Graph Neural Processes for Spatio-Temporal Extrapolation

1 code implementation30 May 2023 Junfeng Hu, Yuxuan Liang, Zhencheng Fan, Hongyang Chen, Yu Zheng, Roger Zimmermann

We study the task of spatio-temporal extrapolation that generates data at target locations from surrounding contexts in a graph.

Decoupling Long- and Short-Term Patterns in Spatiotemporal Inference

no code implementations16 Sep 2021 Junfeng Hu, Yuxuan Liang, Zhencheng Fan, Li Liu, Yifang Yin, Roger Zimmermann

Specifically, we introduce a joint spatiotemporal graph attention network to learn the relations across space and time for short-term patterns.

Predicting Long-Term Skeletal Motions by a Spatio-Temporal Hierarchical Recurrent Network

1 code implementation6 Nov 2019 Junfeng Hu, Zhencheng Fan, Jun Liao, Li Liu

The primary goal of skeletal motion prediction is to generate future motion by observing a sequence of 3D skeletons.
