An enhancement of the original algorithm, as well as the introduction of several hierachical levels enables the discovery of complex structures as present in this type of applications. Furthermore, an integration of unsupervised neural networks with hidden markov models is proposed.enUniversitätsbibliothek DortmundHidden Markov Modelsprotein sequencessleep apneatumor classificationunsupervised neural networks310report
