nice explanation of eigen vectors and its corresponding values; also the geometric picture of spread of the information on 2dto1d!!

Thank you sir. Brilliant methods and explanations to help a near beginner trying to grasp the nuance of eigenvalues and eigenvectors as applied in PCA and unsupervised machine learning. I'm not there yet, but I sure feel like I can and will after listening to you. Who needs machines ... lol?

In 1:57 covariance matrix says Cov of X(S)= Transpose(X).X But in previous vedio we saw Cov of X(S)=1/n( Transpose(X).X ) ..Why this difference??

Thank you verymuch
It covers
1. column std. matrix
2.Co variance matrix
3.eigen vector
4.eigen value
5.Orthogonal matrix of v1, v2, .... vd
6.projection
7.projection 100%, 75%, 60%, 50%
In general, for any matrix, the eigenvectors are NOT always orthogonal. But for a special type of matrix, symmetric matrix, the eigenvalues are always real and the always orthogonal.

7:57 Always true only if it's a symmetric matrix

Sir, what is the purpose of using covariance matrix?

msravya

I dint understand anything from this. Do I need to watch any prior video relates to pca in order to understand this videos concepts

gurudakshin

sir why cant we take v2 as our vector having maximum variance in a particular direction
