Diego Fernando Peña-Unigarro

Email: diferpun@gmail.com

He is an electronic engineer from Universidad de Nariño. His research focuses are on control systems and machine learning. Since he has had the opportunity to attended a number of international conferences abroad, he has developed research skills and got published some papers related mainly to data visualization and dimensionality reduction. He has been involved as an auxiliary researcher in some projects on biological signal processing and classification, dimensionality reduction in order to address visualization problems, as well as applications of data mining techniques for land cover classification tasks of Lansat 8 images. Also, he has developed strong programming skills such as: Netbeans-java, Android Studio, Matlab, QGIS y PostgreSQL.

Research Interests

Signal processing, image processing, pattern recognition, data visualization and dimessionality reduction
