A Hierarchical Taxonomy For Deep State Space Models

Shiqin Tang, Pengxing Feng, Shujian Yu, Yining Dong, S. Joe Qin

ICASSP 2025accepted

Modeling nonlinear dynamical systems is a challenging task in fields such as speech processing, music generation, and video prediction. This paper introduces a hierarchical framework for Deep State Space Models (DSSMs), categorizing them by their conditional independence properties and Markov assump…

Community-Aware Variational Autoencoder for Continuous Dynamic Networks

Junwei Cheng, Chaobo He, Pengxing Feng, Weixiong Liu, Kunlin Han, Yong Tang

AAAI 2025technical

Variational autoencoder performs well in community detection on static networks, but it is difficult to directly extend to continuous dynamic networks. The main reason is that traditional methods mainly rely on adjacency structures to complete the inference and generation processes. However, continu…
