On the VC-dimension of half-spaces with respect to convex sets

Nicolas Grelier, Saeed Gh. Ilchi, Tillmann Miltzow +1

A family S of convex sets in the plane defines a hypergraph H = (S, E) as follows. Every subfamily S' of S defines a hyperedge of H if and only if there exists a halfspace h that f…

On Statistical Learning of Simplices: Unmixing Problem Revisited

Amir Najafi, Saeed Ilchi, Amir H. Saberi +3

We study the sample complexity of learning a high-dimensional simplex from a set of points uniformly sampled from its interior. Learning of simplices is a long studied problem in c…

On uniquely k-list colorable planar graphs, graphs on surfaces, and regular graphs

M. Abdolmaleki, J. P. Hutchinson, S. Gh. Ilchi +2

A graph is called uniquely k-list colorable (ULC) if there exists a list of colors on its vertices, say , each of size , such that…
