Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

In this paper, a decentralized implementation of heat kernel smoothing (HKS) is presented by using a rational graph filtering method. First, the basics of graph signal processing (GSP) are briefly ...

For node level graph encoding, a recent important state-of-art method is the graph convolutional networks (GCN), which nicely integrate local vertex features and graph topology in the spectral domain.
