Okay, I'm trying to create the inverse filter for a blur filter (not the usual sharpen filter). I have the forward transform matrix (taking a vector of all the pixels), and I want to invert it.

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 ...

Dr. James McCaffrey of Microsoft Research guides you through a full-code, step-by-step tutorial on "one of the most important operations in machine learning." Computing the inverse of a matrix is one ...

This is a whole lesson to go through Inverse Matrices. It introduces and clearly explains how to use the formula to find the inverse as well as looking at the concept of the inverse or reciprocal in ...

In 1948, Alan Turing came up with LU decomposition, a way to factor a matrix and solve \(Ax=b\) with numerical stability. Although there are many different schemes to factor matrices, LU decomposition ...

This is a whole lesson on Inverse Matrices. The lesson looks at using the method of using the simultaneous equations to find inverse matrices. This is the second lesson on inverse matrices and builds ...
