    • Sparse Approximate Conic Hulls 

      Van Buskirk, Gregory (2017-12)
      We consider the problem of computing a restricted nonnegative matrix factorization (NMF) of an m x 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 ∈ ...
