In research , the minimization function has not got any regularization term. To test how the regularization terms has an effect on face recognition accuracy, here we reimplemneted mention algorithm and also proposed new regularization term which is in L2 norm.

Hi Osama, it is probably because of dataset somehow was not read. Please check all files under data/CroppedTale folder into your current directory.
Undefined function or variable 'height'.
