Research activity

I am a PhD in the field of Artificial Intelligence and Data Mining. I am also currently working in the University of Almeria as a researcher, in the field of probabilisitic modeling with deep neural networks.

During my thesis I focused on Fuzzy Logic and Fuzzy Rule Based Systems applied on high dimensional problems. In order to build models from high dimensional data sets (which have a large number of variables) efficiency is a must. In that way, our aim is to design computationaly efficient learning algorithms that generate accurate and simple models (a balance of both properties are desired for this kind of models).

In the following I show the research projects that I am/was a member. Also, I show my publications and a link to view them online if it is possible.
