    Author : Berkant Savas; Lars Eldén; Lieven De Lathauwer; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volume; Minimization criterion; Determinant; Rank deficient matrix; Reduced rank regression; System identification; Rank reduction; Volume minimization; General algorithm; Handwritten digit classification; Tensors; Higher order singular value decomposition; Tensor approximation; Least squares; Tucker model; Multilinear algebra; Notation; Contraction; Tensor matricization; Newton s method; Grassmann manifolds; Product manifolds; Quasi-Newton algorithms; BFGS and L-BFGS; Symmetric tensor approximation; Local intrinsic coordinates; Global embedded coordinates; ; Numerical analysis; Numerisk analys;

    Abstract : In many fields of science, engineering, and economics large amounts of data are stored and there is a need to analyze these data in order to extract information for various purposes. Data mining is a general concept involving different tools for performing this kind of analysis. READ MORE

  4. 2. Adaptive Control based on Explicit Criterion Minimization

    Author : Eva Trulsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive control; Optimization; Identification; On-line operation;

    Abstract : A common approach to regulator design is to define an objective function, which is minimized with respect to adjustable regulator parameters. Here we discuss how such objective functions can be minimized online, thus providingadaptive eon tro I. READ MORE

  5. 3. On Nuclear Norm Minimization in System Identification

    Author : Niclas Blomberg; Bo Wahlberg; Cristian Rojas; Kristiaan Pelckmans; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In system identification we model dynamical systems from measured data. This data-driven approach to modelling is useful since many real-world systems are difficult to model with physical principles. Hence, a need for system identification arises in many applications involving simulation, prediction, and model-based control. READ MORE

  6. 4. Energy efficient multi-robot coordination

    Author : Oskar Wigström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduling; optimization; hybrid systems; multi-robot systems; energy minimization;

    Abstract : When multiple systems work in the same physical environment, it is important to ensure that no collisions occur. This thesis is focused on the centralized offline coordination of such collaborating systems, with the condition that the spatial path each system travels along is known before hand. READ MORE

  7. 5. Minimizing Regret in Combinatorial Bandits and Reinforcement Learning

    Author : Mohammad Sadegh Talebi Mazraeh Shahi; Alexandre Proutiere; Mikael Johansson; Ronald Ortner; KTH; []
    Keywords : Multi-armed Bandits; Reinforcement Learning; Regret Minimization; Statistics; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis investigates sequential decision making tasks that fall in the framework of reinforcement learning (RL). These tasks involve a decision maker repeatedly interacting with an environment modeled by an unknown finite Markov decision process (MDP), who wishes to maximize a notion of reward accumulated during her experience.
