Description

This data set contains vectorised images of the faces of 10 different human subjects with different poses and lighting conditions. The images were compressed to 30x20 pixels.

Usage

yale

Format

A list with entries $x (a 2000x600 matrix with each row corresponding to an image) and $y (a vector of labels indicating the human subject).
