Condition number is a measure of the sensitivity of a function's output with respect to its input. In the context of a matrix, it is the ratio of the largest singular value of the matrix to the ...

Abstract: We present experimental results of comparing the modified K-nearest neighbor (MkNN) algorithm with support vector machine (SVM) in the prediction of condition numbers of sparse matrices.

In this paper, the unitarily invariant norm ∥·∥ on 𝕔m×n is used. We first discuss the problem under what case, a rectangular matrix A has minimum condition number K(A) = ∥A∥ ∥A⁺∥, where A⁺ designates ...
