Machine learning on Graphs
Prof. Chanyoung Park
KAIST, Korea
Abstract
Graphs are data structures that express the connection relationships between individuals, and are widely used to express various phenomena in real life. Representative examples include user's social networks, knowledge graphs, molecular structure graphs, protein-protein interaction graphs, and gene graphs. In order to improve the performance of graph-based machine learning models, it is essential to learn the representation of nodes and edges in consideration of the structure of the graph. To this end, with the recent development of deep learning technology, machine learning techniques for graph analysis are in the spotlight.
This tutorial aims to provide an introduction to the basics of recent advances in machine learning on graphs. More specifically, I will mainly discuss about recent machine learning techniques to learn representations of nodes in various types of graph, including homogeneous, multi-aspect, attributed, and heterogeneous graph. Moreover, I will introduce interesting applications of graph machine learning. This tutorial is self-contained and designed for introductory and intermediate audiences. No special prerequisite knowledge is required to attend this tutorial.
