From Local to Global: Spectral-Inspired Graph Neural Networks

We propose spectral-inspired GNNs that exploit the advantages from both global and local methods.

A Simple Spectral Failure Mode for Graph Convolutional Networks

A simple generative model in which spectral graph embedding for subsequent inference succeeds whereas unsupervised GCN fails.

Autonomous driving

A CNN encoder-decoder model to navigate traffic environment using bird's eye view images.

Adversarial attacks against linear and deep-learning regressions in astronomy

Our work generalizes adversarial attacks in regression settings and develops a comprehensive approach to measure attack success.
