In the literature, most work utilize multivariate Gaussian models for the mentioned applications, mainly due to the lack of efficient analytical tools for modeling with non-Gaussian distributions. In this paper, we propose a particle filtering approach which can model non-Gaussian autoregressive processes having cross-correlations among them. Moreover, time-varying parameters of the process can be modeled as the most general case by using this sequential Bayesian estimation method. Simulation results justify the performance of the proposed technique, which potentially can model also Gaussian processes as a sub-case.</subfield> </datafield> <datafield tag="650" ind1="1" ind2="7"> <subfield code="2">opendefinition.org</subfield> <subfield code="a">cc-by</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">CNR, Area Ric, ISTI, I-56124 Pisa, Italy</subfield> <subfield code="a">Kuruoglu, Ercan E.</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Bogazici Univ, Elect & Elect Engn Dept, TR-34342 Istanbul, Turkey</subfield> <subfield code="a">Ertuzun, Aysin</subfield> </datafield> <datafield tag="980" ind1=" " ind2=" "> <subfield code="b">article</subfield> <subfield code="a">publication</subfield> </datafield> <datafield tag="542" ind1=" " ind2=" "> <subfield code="l">open</subfield> </datafield> <datafield tag="100" ind1=" " ind2=" "> <subfield code="a">Gencaga, Deniz</subfield> </datafield> <datafield tag="260" ind1=" " ind2=" "> <subfield code="c">2010-01-01</subfield> </datafield> <controlfield tag="005">20210315122848.0</controlfield> <datafield tag="909" ind1="C" ind2="O"> <subfield code="o">oai:zenodo.org:27957</subfield> <subfield code="p">user-tubitak-destekli-proje-yayinlari</subfield> </datafield> <datafield tag="856" ind1="4" ind2=" "> <subfield code="z">md5:d1cd4d15c2eea5044db308f128eb3e77</subfield> <subfield code="s">199</subfield> <subfield code="u">https://aperta.ulakbim.gov.trrecord/27957/files/bib-05980d65-9117-404e-b202-df361aab6974.txt</subfield> </datafield> <datafield tag="540" ind1=" " ind2=" "> <subfield code="u">http://www.opendefinition.org/licenses/cc-by</subfield> <subfield code="a">Creative Commons Attribution</subfield> </datafield> <datafield tag="024" ind1=" " ind2=" "> <subfield code="a">10.1007/s11045-009-0081-8</subfield> <subfield code="2">doi</subfield> </datafield> </record>
