Ensemble Gaussian Processes for Online Learning Over Graphs With Adaptivity and Scalability

In the past decade, semi-supervised learning (SSL) over graphs has gained popularity due to its importance in a gamut of network science applications. While most of existing SSL methods provide only point estimates of the targeted variables, the present work capitalizes on Gaussian processes (GPs) t...
