The Variational Bayes (VB) procedure is used to restore conjugacy. The resulting Bayesian recursive identication procedure has many of the desirable computational proper- ties of the classical RLS procedure. During each time-step, an iterative Variational EM (VEM) procedure is required to obtain the necessary moments. The procedure is used to reconstruct an outlier-corrupted AR process.</abstract> <abstract language="cze" primary="0">Tradiční autoregresní (AR) model je rozšířen o možnost modelování široké škály možných transformací. Aproximační metoda Variační Bayes (VB) je použita k odhadování parametrů tohoto modelu. Výsledný algoritmus má výhodné výpočetní vlastnosti, srovnatelné s klasickými RLS algoritmy. V každém časovém kroku je však třeba provádět iterační výpočet momentů distribucí na parametrech. Popsaný algoritmus je aplikován na odstranění šumu z AR procesů.</abstract>  <action target="WRD"> <ARLID>cav_un_auth*0213172</ARLID> <name>ICASSP 2005</name> <place>Philadelphia</place> <country>US</country> <dates>18.03.2005-23.03.2005</dates>  </action>     <RIV>BC</RIV> <reportyear>2010</reportyear>   <department>AS</department>    <permalink>http://hdl.handle.net/11104/0131512</permalink>       <arlyear>2005</arlyear>       <unknown tag="mrcbU63"> Proceedings of the IEEE International Conference on Acoustics, Speech, and Signal Processing 0-7803-8874-7 117 120 Philadelphia IEEE 2005 </unknown> </cas_special> </bibitem>
