Скачать или смотреть What a MATRIX actually does | Transformations and Linear Dependency | Day 02

Most people see a matrix and think: "just a grid of numbers."

They're wrong.

A matrix is a transformation of space — a recipe for stretching,
rotating, or shearing an entire coordinate system.

In this video:
→ What basis vectors actually are (î and ĵ)
→ How a matrix × vector moves a point through space
→ Scale, Rotation & Shear — visualized as space transforming
→ Inverse transforms — undoing a transformation
→ Why det = 0 means space collapses (and inverse dies)
→ Linear Independence vs Dependence — in 2D AND 3D
→ What happens when you chain transformations
→ Where all of this lives in Neural Nets, Attention, PCA & SVMs

This is the mental model that makes the rest of ML math click.
