    • Geometrical models for time series analysis 

      Pardo Fernández, Àlex (Universitat Politècnica de Catalunya, 2015-10-23)
      Master thesis
      Open Access
      In this work, a new approach to one class classification is proposed using geometrical models. The proposal is based on the kernelization of a technique of Approximate Polytope Ensemble (APES). It is named Kernel Approximate ...

    • Hyperparameter optimization of svm stochastic processes 

      Martínez Martínez, Pablo (Universitat Politécnica de Catalunya, 2017-10-24)
      Master thesis
      Open Access
      In this work we propose a SSGD based gamma optimization algorithm for Support Vector Machines model. This algorithm is combined with a nouvelle regularization technique called model dropout that make our algorithm competitive ...

    • Relighting the scene by finding the intrinsic images 

      Rafael Antón, Eduard (Universitat Politècnica de Catalunya, 2013-06-14)
      Master thesis
      Open Access
      In this project we will embed virtual objects in a real-life scene looking auto- matically for the most realistic approach. Previous works have demonstrated the lighting as the most important feature to achieve a better ...
