Check out the new article: Matrix Factorization: The Basics.
Since the goal here is didactic, we will proceed as simply as possible. That is, we will implement only what we need: matrix multiplication. You will see today that this is enough to simulate matrix-scalar multiplication. The most significant difficulty that many people encounter when implementing code using matrix factorization is this: unlike scalar factorization, where in almost all cases the order of the factors does not change the result, this is not the case when using matrices.
Welcome everyone to my new article with educational content.
In this article, we will talk about matrix calculations. Dear readers, do not rush to refuse reading this article, thinking that we will talk about something purely mathematical and too complicated. Contrary to what many people think, a good programmer is not someone who writes a giant program that only they can understand, or someone who writes code in a trendy programming language. A real and good programmer understands that a computer is nothing more than a computing machine to which we can tell how computations should be performed. It doesn't matter what exactly we are creating, it can be a simple text editor that does not contain any mathematical code. But this is just an illusion. Even a text editor contains a fair amount of math in its code, especially if it has a spell checker built into it.
