In this thesis, we develop an extension of the hidden markov model (hmm) that addresses two of the most important challenges of financial time series modeling: non-stationary and non-linearity specifically, we extend the hmm to include a novel exponentially weighted expectation-maximization (em) algorithm to handle. Distinct from markov models, hmms assume that an unobserved sequence governs the observed sequence and the markovian property is imposed on the hidden chain rather than the observed one in the first part of this dissertation, we develop a model for hmms with exponential family distribution and.
Hidden markov models and their application to genome analysis in the context of protein structure julian gough (sidney sussex college) summary the bulk of the thesis is concerned with the application of hidden markov models (hmms) to remote protein homology detection the thesis both addresses how best to utilise. Veloped previously for reconstructing haplotypes from population data in this thesis, a new population-based method is developed using a hidden markov model (hmm) for the source of ancestral haplotype segments a higher-order markov model is used to account for linkage disequilibrium in the ancestral haplotypes.
In this thesis, we examine a recently developed method, which extends the forward and viterbi algorithm for hidden markov models genes are the parts of dna that are used in the synthesis of proteins, and hidden markov models are an important tool in the analysis of biologi- cal sequences such as dna we examine the. Abstract in this thesis a model for predicting a person's monthly average of self- rated health the following month was developed it was based on statistics from a form constructed by healthwatch the model used is a hidden markov algorithm based on hidden markov models where the hidden part is the future value of.
