Data analytics on graphs part III: Machine learning on graphs, from graph topology to applications
Modern data analytics applications on graphs often operate on domains where graph
topology is not known a priori, and hence its determination becomes part of the problem …

Predicting Graph Signals using Kernel Regression where the Input Signal is Agnostic to a Graph
We propose a kernel regression method to predict a target signal lying over a graph when
an input observation is given. The input and the output could be two different physical …
