  • Sparse Approximate Conic Hulls 

    Van Buskirk, Gregory; Raichel, Benjamin; Ruozzi, Nicholas
    We consider the problem of computing a restricted nonnegative matrix factorization (NMF) of an m × n matrix X. Specifically, we seek a factorization X ≈ BC, where the k columns of B are a subset of those from X and C ∈ ...
  • Geometric Packing Under Nonuniform Constraints 

    Ene, Alina; Har-Peled, Sariel; Raichel, Benjamin A. (SIAM Publications, 2018-10-22)
    We study the problem of discrete geometric packing. Here, given weighted regions (say, in the plane) and points (with capacities), one has to pick a maximum weight subset of the regions such that no point is covered more ...
