Topological Effects on Attacks Against Vertex Classification

2020 · arXiv (Cornell University)

Vertex classification is vulnerable to perturbations of both graph topology and vertex attributes, as shown in recent research. As in other machine learning domains, concerns about robustness to adversarial manipulation can prevent potential users from …

L2P: Learning to Place for Estimating Heavy-Tailed Distributed Outcomes

2019 · arXiv (Cornell University)

Many real-world prediction tasks have outcome variables that have characteristic heavy-tail distributions. Examples include copies of books sold, auction prices of art pieces, demand for commodities in warehouses, etc. By learning heavy-tailed distributions, "big and …
