  1. 1. Minimax Approaches to Robust Model Predictive Control

    Författare :Johan Löfberg; Torkel Glad; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MPX; Minimax algorithms;

    Sammanfattning : Controlling a system with control and state constraints is one of the most important problems in control theory, but also one of the most challenging. Another important but just as demanding topic is robustness against uncertainties in a controlled system. LÄS MER

  3. 2. Priors and uncertainty in reinforcement learning

    Författare :Emilio Jorge; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian reinforcement learning; reinforcement learning; Minimax; Markov decision processes;

    Sammanfattning : Handling uncertainty is an important part of decision-making. Leveraging uncertainty for guiding exploration to discover higher rewards has been a standard approach for a long time, using both ad hoc and more principled approaches. LÄS MER

  4. 3. Data driven modeling in the presence of time series structure: : Improved bounds and effective algorithms

    Författare :Othmane Mazhar; Boualem Djehiche; Munther Dahleh; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time series; Non-asymptotic estimation; Minimax; Change point detection; Hidden Markov model; State space model; Least square; Penalized Regression; Random covariance matrix; Concentration inequality; Chaining integral; Self-normalized martingale inequality; Cramér-Rao inequality; van Trees inequality; Matematisk statistik; Mathematical Statistics;

    Sammanfattning : This thesis consists of five appended papers devoted to modeling tasks where the desired models are learned from data sets with an underlying time series structure. We develop a statistical methodology for providing efficient estimators and analyzing their non-asymptotic behavior. LÄS MER

  7. 5. An Analysis of Consequences of Land Evaluation and Path Optimization

    Författare :Rachel Mundeli Murekatete; Takeshi Shirabe; Gerhard Navratil; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Least-cost paths; Most-suitable paths; Raster cost surfaces; Raster suitability surfaces; Shortest path problem; Minimax path problem; Scales of measurement; Minsta-kostnad rutter; Mest-lämpliga rutter; Raster kostnadsytor; Raster lämplighets ytor; kortaste vägen problem; Minimax väg problem; Mätskalor; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : Planners who are involved in locational decision making often use raster-based geographic information systems (GIS) to quantify the value of land in terms of suitability or cost for a certain use. From a computational point of view, this process can be seen as a transformation of one or more sets of values associated with a grid of cells into another set of such values through a function reflecting one or more criteria.
