Independent component analysis and beyond / Independent component analysis and beyondHarmeling, Stefan January 2004 (has links)
'Independent component analysis' (ICA) ist ein Werkzeug der statistischen Datenanalyse und Signalverarbeitung, welches multivariate Signale in ihre Quellkomponenten zerlegen kann. Obwohl das klassische ICA Modell sehr nützlich ist, gibt es viele Anwendungen, die Erweiterungen von ICA erfordern. In dieser Dissertation präsentieren wir neue Verfahren, die die Funktionalität von ICA erweitern:
(1) Zuverlässigkeitsanalyse und Gruppierung von unabhängigen Komponenten durch Hinzufügen von Rauschen,
(2) robuste und überbestimmte ('over-complete') ICA durch Ausreissererkennung, und
(3) nichtlineare ICA mit Kernmethoden. / Independent component analysis (ICA) is a tool for statistical data analysis and signal processing that is able to decompose multivariate signals into their underlying source components. Although the classical ICA model is highly useful, there are many real-world applications that require powerful extensions of ICA. This thesis presents new methods that extend the functionality of ICA:
(1) reliability and grouping of independent components with noise injection,
(2) robust and overcomplete ICA with inlier detection, and
(3) nonlinear ICA with kernel methods.
