+# Example learning task, we report the lines of code needed to perform a PCA followed by a SVM classification. 
+# In particular, we detail the operational steps needed to project the samples of a UCI5 dataset on the cartesian plane 
+# generated by the first two principal components, to train a kernel SVM on the projected data and to test 
+# the trained model on the same data. 
+#
+# The dataset chosen for this dimensionality reduction example is the Iris dataset, collecting 150 observations 
+# of 3 different classes of iris flowers, each described by 4 attributes. 
+# As a working example illustrating the use of the library in a simple machine
