And,

> This is the engine behind image compression

SVD+truncate (or any other low rank approximation) is absolutely not used in any real image compression. Of course, it is a popular classroom project to demonstrate SVD. It's O(n^3) ffs.

Only AI would call SVD the "engine behind image compression", lol.

Im fully aware. But since you came here to criticize only, thanks.

Its one of the simple forms of lossy compression, so you could have just point out that constructively, but hey this is internet.

It would have been in a different tone had it been human written. In fact, if it had not been written with AI, there is no chance SVD gets called the fancy "engine behind image compression", the blog would have said exactly what you said in the comment above: "Its one of the simple forms of lossy compression, here's a simple before/after on a sample image" or whatever.
