First Hitting Diffusion Models for Generating Manifold, Graph and Categorical Data
Mao Ye, Lemeng Wu, Qiang Liu
We propose a family of First Hitting Diffusion Models (FHDM), deep generative models that generate data with a diffusion process that terminates at a random first hitting time. Thi…
Pulse strategy for suppressing spreading on networks
Qiang Liu, Xiaoyu Zhou, Piet Van Mieghem
In networked spreading models, each node can infect its neighbors and cure spontaneously. The curing is assumed to occur uniformly over time. A pulse immunization/curing strategy i…
Network localization is unalterable by infections in bursts
Qiang Liu, Piet Van Mieghem
To shed light on the disease localization phenomenon, we study a bursty susceptible-infected-susceptible (SIS) model and analyze the model under the mean-field approximation. In th…
Die-out Probability in SIS Epidemic Processes on Networks
Qiang Liu, Piet Van Mieghem
An accurate approximate formula of the die-out probability in a SIS epidemic process on a network is proposed. The formula contains only three essential parameters: the largest eig…
