Interactive Interface for Data-Vis

The separately use of data mining methods and data visualization techniques requires mandatorily experts for result interpretation. That fact represents a drawback entailing an increase in processing time, computational load and human work for reaching the main goal for data processing - to infer meaningful information about the analyzed data. The integration of data mining methods and information visualization techniques is a latent need, despite there are tools attempting to carry out this task, the design of a visual analysis system that properly fulfills the User's needs and requirements is still an open issue. One way to make an intelligible visualization of big data volumes is reducing its dimension to obtain human-readily-interpretable data representations.

In this thesis, we propose the implementation of a user-friendly interface allowing for an interaction with the results of data representation by doing a mixture of dimension reduction methods. To this end, we propose a model that performs such a mixture through a geometric approach, whereby a user –no necessarily expert- can intuitively and dynamically manipulate the visual representation of the data using the parameters of a geometric shape.
