1. 1. A Treatise on Measuring Wiener-Granger Causality

   Författare :Mehrdad Jafari-Mamaghani; Joanna Tyrcha; Sebastiano Stramaglia; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Wiener-Granger causality; Information theory; Kernel canonical correlation; Systems Microscopy; Cell migration.; Mathematical Statistics; matematisk statistik;

   Sammanfattning : Wiener-Granger causality is a well-established concept of causality based on stochasticity and the flow of time, with applications in a broad array of quantitative sciences. The majority of methods used to measure Wiener-Granger causality are based on linear premises and hence insensitive to non-linear signals. LÄS MER

3. 2. Inference techniques for stochastic nonlinear system identification with application to the Wiener-Hammerstein models

   Författare :Giuseppe Giordano; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear systems; system identification; stochastic; Maximum Likelihood; Wiener-Hammerstein; Monte Carlo; Newton s method;

   Sammanfattning : Stochastic nonlinear systems are a specific class of nonlinear systems where unknown disturbances affect the system's output through a nonlinear transformation. In general, the identification of parametric models for this kind of systems can be very challenging. LÄS MER

4. 3. Aspects of the Identification of Wiener Models

   Författare :Anna Hagenblad; Lennart Ljung; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : System identification deals with the problem of constructing models of systems from observations of the inputs and outputs to the systems. In this thesis, a particular class of models, Wiener models, is studied. The Wiener model consists of a linear dynamic block, followed by a static nonlinearity. LÄS MER

7. 5. Harmonic signal modeling based on the Wiener model structure

   Författare :Emad Abd-Elrady; Torsten Söderström; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

   Sammanfattning : The estimation of frequencies and corresponding harmonic overtones is a problem of great importance in many situations. Applications can, for example, be found in supervision of electrical power transmission lines, in seismology and in acoustics. LÄS MER
