This method - allows dimensionality reduction, obtaining a generative subspace which is very reliable for - face reconstruction. + We analyze dimensionality reduction with PCA, obtaining a generative subspace which is very reliable for face reconstruction. Furthermore, we evaluate LDA, which is able to perform reliable classification, generating a discriminative subspace, where separation of classes is easier to identify. - 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. - - The data used includes 52 classes with 10 samples each. The number of features is 2576(since the size of the pictures is 46x56). + In the final part we analyze the benefits of using a combined version of the two methods using Fisherfaces and evaluate the benefits of ensemble learning with regards to data and feature space ranodmisation. We find that combined PCA-LDA obtains lower classification error PCA or LDA individually, while also maintaining a low computational costs, allowing us to take advantage of ensemble learning. + The dataset used includes 52 classes with 10 samples each.
