Abstract
Graph based data science lets us leverage the power of relationships and structure in data to improve model prediction and answer previously intractable questions. In this tutorial we will first introduce the graph as a versatile data representation and summarize the different analytics tasks that can be performed over graph structured data. We will go on to detail the different ML/AI tasks that become possible by leveraging using the graph structure of data and describe recent relevant algorithms and techniques. The tutorial will conclude with a demonstration of exploratory analysis over graph data followed by an illustrative link prediction example.
