On one hand we will analyze PCA, Principal Components Analysis. This method allows dimensionality reduction, obtaining a generative subspace which is very reliable for face reconstruction. On the other hand LDA, Linear Discriminant Analysis, allows to perform a very reliable classification, generating a discriminative subspace, in which the separation between classes is easier to recognize. In the final part we will analyze the benefits of using a combined version of the two methods using FIsherfaces. As we will see, the PCA-LDA ensemble will obtain much more accurate results with a very high speed of computation. ...
