What are the standard non-deep learning based supervised dimensionality reduction techniques ? The ones I know of are Linear Discriminant Analysis. Is there a Supervised version of PCA ?

better to go with Fisher Discriminant analysis (FDA). If you wanna apply PCA in a supervised way then apply independently to each class.

Hi, you can find an article on Supervised PCA here https://www.sciencedirect.com/science/article/pii/S0031320310005819
and a python implementation of supervised PCA here
