Abstract:   

Graph-structured data and point cloud data are ubiquitous across scientific fields. Geometric deep learning (GDL) has recently been widely applied to solve prediction tasks with such data. GDL models are often designed with complex equivariant structures to preserve geometric principles and are thus hardly interpretable. Moreover, GDL models also risk capturing spurious correlations between the input features and labels, which poses many concerns to scientists who aim to deploy these models in scientific analysis and experiments. In this talk, I will introduce our recent project on interpretable and trustworthy GDL models with applications with scientific data analysis. Our approach is based on a novel learnable randomness injection (LRI) mechanism, which is grounded by the information-bottleneck principle and can be applied to general GDL backbones. I will also introduce our recently established benchmarks with real-world applications in high energy physics and biochemistry to evaluate interpretable and trustworthy GDL models.
