Abstract: Abstract In the previous chapters, several methods of data classification and regression were presented. Reference was made to the dimensionality ratio problem, which led us to describe and use variable selection techniques. The problem with these techniques is that they cannot detect hidden variables in the data, responsible for interesting data variability. In the present chapter we describe techniques that allow us to analyse the data structure with the dual objective of dimensional reduction and improved data interpretation.
