Research Type Theoretical The paper introduces the notion of Interpolative Convex Rank(ICR) of a matrix, and shows that k = ICR of a subset smoothed data matrix where k is the number of vertices in Lk P (see details in Theorem 1). The paper introduces new techniques based on the hyperplane separator theorem for proving lower bounds on the ICR of a matrix (see details in Section 3.4). Under standard assumptions, the paper gives a polynomial time algorithm for finding the correct value of the number of vertices of the polytope K (see Theorem 18).
