An **Eigenvector** of matrix A is a non-zero vector that only scales (doesn't change direction) when A acts on it (`Av=λv`). **Eigenvalue** (λ) is the scalar. Pro-Tip: Key for stability & system analysis!

In PCA, eigenvalues represent the variance explained by each principal component, while eigenvectors determine the direction of these components, illustrating how the original variables are weighted.

Do I know and physicists who've wrapped their head around AI? #AI #Physics #Eigenvectors

I plan my routes (hiking, running, cycling) using heatmaps of other people's trips in @Strava.
How can we prevent converging to an equilibrium where we just copy shitty routes from ready other? Does the answer involve #eigenvectors?

#Eigenvectors and #eigenvalues are beaut things. They are ESNTL for doing Principal Component Analysis (#PCA) which is an imp. technique in #UnsupervisedLearning. #PCA allows us to greatly reduce the dimensionality of datasets and keep most of the imp. info

I've learned to calculate #Eigenvalues and #Eigenvectors 25 years ago and got a perfect grade.
However, I never understood, why we were learning this.
https://www.youtube.com/watch?v=PFDu9oVAE-g perfectly explained the basics and the motivation within 17 minutes. 👍
