Data Classification

Project description

    Due to its application in different areas, classification has been one of the most important data mining tasks. In this task, Perceptron Trees (AP) have been used with good results. A Differential Evolution algorithm can be used to evolve these trees. We also introduce the concept of legitimacy, which is used to reduce evaluation costs, portion of the algorithm that most consumes time.

Subprojects

Artificial Neural Networks

    Artificial Neural Networks (ANN) applied to the Traveling Salesman Problem (TSP). As the TSP is a NP problem, the use of ANN offers a choice of cost / benefit regarding the quality of solutions and processing time. The TSP has applications in planning, logistics, manufacturing microchips and DNA sequencing.
