Investigating Differentiable Graph Module

Anees Kazi

Graph deep learning has recently emerged as a powerful technique especially in the medical domain. Graph-based methods have shown promising results on a broad spectrum of applications ranging from social science, biomedicine, and particle physics to computer vision, graphics, and chemistry. One of the current problems with most of the GCN based methods is the requirement of a pre-computed graph. However, in many scenarios, especially in the medical and healthcare domain, the graph may not be given. 


In this project, we will explore how such a graph can be learned mainly for medical applications. Given the population of individuals, we focus on predicting the age and gender of each based on brain MRI features. The method is inspired by our recent work on the differentiable graph module [1, 2] which can be further extended to any problem where the graph is unknown and can be inferred from the input features. With this project, you get to learn how to define a graph learning problem in the non-/ medical domain and further collaboration with a brain mesh analysis project.
