Threshold for Detecting High Dimensional Geometry in Anisotropic Random Geometric Graphs

Matthew Brennan, Guy Bresler, Brice Huang

In the anisotropic random geometric graph model, vertices correspond to points drawn from a high-dimensional Gaussian distribution and two vertices are connected if their distance…

The staircase property: How hierarchical structure can guide deep learning

Emmanuel Abbe, Enric Boix-Adsera, Matthew Brennan +2

This paper identifies a structural property of data distributions that enables deep neural networks to learn hierarchically. We define the "staircase" property for functions over t…
