This VB-filtering scheme is used to identify a Hidden Markov model with an unknown non-stationary transition matrix. In a simulation study involving soft-bit data, reliable inference oh the underlying binary sequence is archieved in tandem with estimation of the transition probabilities.</abstract> <abstract language="cze" primary="0">Aproximační techniku Variační Bayes je možné aplikovat v oblasti Bayesovského filtrování pro řadu nestacionárních parametrických modelů. Metoda je ilustrována na příkladu Markovova modelu se skrytými parametry a nestacionární maticí přechodu. Na simulacích je ukázáno, že metoda produkuje dobré odhady jak skrytého parametru tak matice přechodu.</abstract>  <action target="WRD"> <ARLID>cav_un_auth*0215014</ARLID> <name>IEEE International Conference on Acoustics, Speech and Signal Processing</name> <place>Toulouse</place> <dates>14.05.2006-19.05.2006</dates>  <country>FR</country> </action>    <reportyear>2007</reportyear>  <RIV>BD</RIV>      <permalink>http://hdl.handle.net/11104/0133240</permalink>       <arlyear>2006</arlyear>       <unknown tag="mrcbU63"> cav_un_epca*0076504 Proceedings of the IEEE International Conference on  Acoustics, Speech and Signal Processing 1-4244-0469-X 1 4 Bryan IEEE 2006 </unknown> </cas_special> </bibitem>
