Can GNNs compute the shortest path? Or min-cut? Or more generally, are GNNs aligned with dynamic programs? We provide an answer in arxiv.org/pdf/2202.08833…; joint work with Mohammad Fereydounian, @JDadashkarimi, and @aminkarbasi 1/

#Neurips2021 How does a Neural Network's Architecture Impact its Robustness to Noisy Labels? arxiv.org/abs/2012.12896 (Arxiv version will be updated soon) Joint work with @mozhi_zhang @KeyuluXu @johnpdickerson, and Jimmy Ba











How do neural networks extrapolate, i.e., predict outside the training distribution? We study MLPs and Graph Neural Networks trained by gradient descent, and show how a good representation and architecture can help extrapolation. arxiv.org/abs/2009.11848
