Moreno Vega, Alberto (Date of defense: 2019-03-08)
Improvements in circuit manufacturing have allowed, along the years, increasingly complex designs. This has been enabled by the miniaturization that circuit components have undergone. But, in recent years, ...
Rahmani, Vahid (Date of defense: 2020-11-18)
Pathfinding for autonomous agents and robots has been traditionally driven by finding optimal paths. Where typically optimality means finding the shortest path between two points in a given environment. However, optimality ...
Xenos, Alexandros (Date of defense: 2024-02-02)
(English) The recent technological advances in high-throughput sequencing have yielded vast amounts of large-scale biological omics data that describe different aspects of cellular functioning. These omics data are typically ...
Zavala, Edith (Date of defense: 2019-07-05)
Nowadays, most of the approaches supporting self-adaptive systems (SASs) rely on static feedback control loops, for managing their adaptation process. One of the most popular feedback loops is the MAPE-K loop. In this loop, ...
Prat Masramon, Gabriel (Date of defense: 2016-02-01)
In this thesis we study feature subset selection and feature weighting algorithms. Our aim is to make their output more stable and more useful when used to train a classifier. We begin by defining the concept of stability ...
