Computing the inverse of a matrix is one of the most important operations in machine learning. If some matrix A has shape n-by-n, then its inverse matrix Ai is n-by-n and the matrix product of Ai * A ...

Inverting a matrix is one of the most common tasks in data science and machine learning. In this article I explain why inverting a matrix is very difficult and present code that you can use as-is, or ...

A hyper-invertible matrix is a matrix whose every non-trivial square sub-matrix is invertible. Any m-by-n matrix induces a (linear) mapping from n input values to m output values; if the matrix is ...
