    Sammanfattning : Background: In social sciences the quality of life (QOL) concept is often connected with efforts to evaluate welfare and well being. In medicine QOL is frequently used as a complement to evaluations of cure. In psychiatry QOL is of special importance because many patients have to endure long periods of illness. LÄS MER

  5. 4. Applications of Information Inequalities to Linear Systems : Adaptive Control and Security

    Författare :Ingvar Ziemann; Henrik Sandberg; Alexandre Proutiere; Nikolai Matni; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stochastic Adaptive Control; Machine Learning; Fisher Information; Secure Control; Fundamental Limitations; Reinforcement Learning; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis considers the application of information inequalities, Cramér-Rao type bounds, based on Fisher information, to linear systems. These tools are used to study the trade-offs between learning and performance in two application areas: adaptive control and control systems security. LÄS MER
