Irregular layout for a satellite’s interferometric array

Published in IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021

Training Neural Networks to Predict Graphs. Who is afraid of the big bad NP-hardness ?

Published:

Graph learning is a rapidly growing area of machine learning, with most advances focused on problems where graphs are the input. Yet, many important tasks involve predicting graphs as the output. This setting poses a fundamental challenge: evaluating predictions requires solving the graph matching problem, an NP-hard task. In this talk I will: (a) review existing strategies to circumvent this obstacle, such as graph canonization and generative approaches; (b) demonstrate that, in a data-driven setting, the hardness barrier can effectively disappear as, for a given graph distribution, it is possible to learn a scalable solver; and (c) showcase how this strategy can be used to train a graph-level autoencoder i.e. a model that learns to encode (and decode) entire graphs into a vector space.
