  1. 11. Sequential Monte Carlo for inference in nonlinear state space models

    Författare :Johan Dahlin; Thomas Schön; Fredrik Lindsten; Adam M. Johansen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nonlinear state space models (SSMs) are a useful class of models to describe many different kinds of systems. Some examples of its applications are to model; the volatility in financial markets, the number of infected persons during an influenza epidemic and the annual number of major earthquakes around the world.

  3. 12. Identification using Convexification and Recursion

    Författare :Liang Dai; Thomas Schön; Magnus Jansson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; System identification; Convex optimization; Recursive Bayesian method; Elektroteknik med inriktning mot signalbehandling; Electrical Engineering with specialization in Signal Processing;

    Sammanfattning : System identification studies how to construct mathematical models for dynamical systems from the input and output data, which finds applications in many scenarios, such as predicting future output of the system or building model based controllers for regulating the output the system.Among many other methods, convex optimization is becoming an increasingly useful tool for solving system identification problems.

  4. 13. Improved diagnosis and prediction of community-acquired pneumonia

    Författare :Alicia Edin; Anders F. Johansson; Anders Sjöstedt; Annika Allard; Thomas Schön; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Community-acquired pneumonia; infection; diagnosis; qPCR; metabolites; metabolomics;

    Sammanfattning : Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality worldwide. Although there is wide variation in the microbial etiology, CAP may manifest with similar symptoms, making institution of proper treatment challenging. LÄS MER

  5. 14. Dual control concepts for linear dynamical systems

    Författare :Mina Ferizbegovic; Håkan Hjalmarsson; Thomas B. Schön; Cristian R. Rojas; Roy Smith; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : We study simultaneous learning and control of linear dynamical systems. In such a setting, control policies are derived with respect to two objectives: i) to control the system as well as possible, given the current knowledge of system dynamics (exploitation), and ii) to gather as much information as possible about the unknown system that can improve control (exploration).

  7. 15. Robust learning and control of linear dynamical systems

    Författare :Mina Ferizbegovic; Håkan Hjalmarsson; Thomas B. Schön; Cristian R. Rojas; Florian Dörfler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : We consider the linear quadratic regulation problem when the plant is an unknown linear dynamical system. We present robust model-based methods based on convex optimization, which minimize the worst-case cost with respect to uncertainty around model estimates. LÄS MER
