-The process for alternative method is somewhat similar to LDA. One different
-subspace is generated for each class. These subspaces are then used for reconstruction
-of the test image and the class of the subspace that generated the minimum reconstruction
-error is assigned.
+The process for alternative method is draws similarities to LDA. Similarly to LDA it calculates per class means. It then projects 
+images onto eigenvectors from subspaces generated per each class. While it does not attempt to discriminate features per class, the
+calculation of independent class subspaces is effective at differentiating between the classes when reconstruction error from each class
+subspace is compared. The class with the subspace that generates the least error is selected as the label.
 
 The alternative method shows overall a better performance (see figure \ref{fig:altacc}), with peak accuracy of 69%
 for $M=5$. The maximum $M$ non zero eigenvectors that can be used will in this case be at most
