    Extending procrustes analysis : building multi-view 2-D models from 3-D human shape samples 

    Pérez Sala, Xavier (Date of defense: 2015-04-29)

    This dissertation formalizes the construction of multi-view 2D shape models from 3D data. We propose several extensions of the well-known Procrustes Analysis (PA) algorithm that allow modeling rigid and non-rigid transformations ...

    Link prediction in large directed graphs 

    Garcia Gasulla, Dario (Date of defense: 2015-04-23)

    The first chapter introduces an approach to machine learning (ML) were data is understood as a network of connected entities. This strategy seeks inter-entity information for knowledge discovery, in contrast with traditional ...

    Monitoring the quality of service to support the service based system lifecycle 

    Oriol Hilari, Marc (Date of defense: 2015-03-19)

    Service Oriented Computing (SOC) has been established in the last recent years as a successful paradigm in Software Engineering. The systems built under this paradigm, known as Service Based System (SBS), are composed of ...

    Visualization and interpretability in probabilistic dimensionality reduction models 

    Tosi, Alessandra (Date of defense: 2014-12-19)

    Over the last few decades, data analysis has swiftly evolved from being a task addressed mainly within the remit of multivariate statistics, to an endevour in which data heterogeneity, complexity and even sheer size, driven ...

    Direct tree decomposition of geometric constraint graphs 

    Tarrés Puertas, Marta Isabel (Date of defense: 2014-12-18)

    The evolution of constraint based geometric models is tightly tied to parametric and feature-based Computer-Aided Design (CAD) systems. Since the introduction of parametric design by Pro/Engineer in the 1980's, most major ...

    Conformance checking and diagnosis in process mining 

    Muñoz Gama, Jorge (Date of defense: 2014-12-19)

    In the last decades, the capability of information systems to generate and record overwhelming amounts of event data has experimented an exponential growth in several domains, and in particular in industrial scenarios. ...

    Simulation, animation and rendering of crowds in real-time 

    Beacco, Alejandro (Date of defense: 2014-12-11)

    Nowadays crowd simulation is becoming more important in computer applications such as building evacuation planning, training, videogames, etc., presenting hundreds or thousands of agents navigating in virtual environments. ...

    Introducing norms into practical reasoning agents 

    Panagiotidi, Sofia (Date of defense: 2014-09-29)

    As distributed electronic systems grow to include thousands of components, from grid to peer-to-peer nodes, from (Semantic) Web services to web-apps to computation in the cloud, governance of such systems is becoming a ...
