Based on the variational Bayesian (VB) method and the cubature information filter (CIF), two adaptive filters, namely centralized adaptive CIF (CA-CIF) and distributed adaptive CIF (DA-CIF), are proposed respectively. First, a series of Bernoulli random variables are introduced as the indicators of measurement loss, and the loss probabilities are modeled as Beta distributions. By transforming all distributions into exponential family form, the CA-CIF can approximate the posterior distributions of the state, loss indicators and loss probabilities by the expectation-maximization (EM) algorithm. To reduce the computational cost and improve the reliability, the DA-CIF is further derived by utilizing the average consensus algorithm. Compared with the existing results which rely on the knowledge of the loss indicators or the loss probabilities, the proposed two filters require no information about the measurement loss, and are thus more applicable for practical scenarios. Finally, two examples of target tracking and permanent magnet synchronous motor are included to validate the feasibility and superiority of the proposed two filters.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A7841828">Cited in <strong>3</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A93E11" title="MSC2020">93E11</a> </td> <td class="space"> Filtering in stochastic control theory </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93E10" title="MSC2020">93E10</a> </td> <td class="space"> Estimation and detection in stochastic control theory </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93C40" title="MSC2020">93C40</a> </td> <td class="space"> Adaptive control/observation systems </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93C10" title="MSC2020">93C10</a> </td> <td class="space"> Nonlinear systems in control theory </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3Amulti-sensor+system">multi-sensor system</a>; <a href="/?q=ut%3Anonlinear+state+estimation">nonlinear state estimation</a>; <a href="/?q=ut%3Ameasurement+loss">measurement loss</a>; <a href="/?q=ut%3Acubature+information+filter">cubature information filter</a>; <a href="/?q=ut%3Avariational+Bayesian+inference">variational Bayesian inference</a></div>  <div class="modal fade" id="metadataModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="myModalLabel">Cite</h4> </div> <div class="modal-body"> <div class="form-group"> <label for="select-output" class="control-label">Format</label> <select id="select-output" class="form-control" aria-label="Select Metadata format"></select> </div> <div class="form-group"> <label for="metadataText" class="control-label">Result</label> <textarea class="form-control" id="metadataText" rows="10" style="min-width: 100%;max-width: 100%"></textarea> </div> <div id="metadata-alert" class="alert alert-danger" role="alert" style="display: none;">  </div> </div> <div class="modal-footer"> <button type="button" class="btn btn-primary" onclick="copyMetadata()">Copy to clipboard</button> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> <div class="functions clearfix"> <div class="function">  <a type="button" class="btn btn-default btn-xs pdf" data-toggle="modal" data-target="#metadataModal" data-itemtype="Zbl" data-itemname="Zbl 1536.93928" data-ciurl="/ci/07841828" data-biburl="/bibtex/07841828.bib" data-amsurl="/amsrefs/07841828.bib" data-xmlurl="/xml/07841828.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/07841828.pdf" title="Zbl 1536.93928 as PDF">Review PDF</a> </div> <div class="fulltexts"> <span class="fulltext">Full Text:</span> <a class="btn btn-default btn-xs" type="button" href="https://doi.org/10.1016/j.ins.2023.02.035" aria-label="DOI for “Centralized and distributed adaptive cubature information filters for multi-sensor systems with unknown probability of measurement loss”" title="10.1016/j.ins.2023.02.035">DOI</a> </div> <div class="sfx" style="float: right;"> </div> </div> <div class="references"> <h3>References:</h3> <table><tr> <td>[1]</td> <td class="space">Al-Janabi, S.; Alkaim, A.; Al-Janabi, E., Intelligent forecaster of concentrations (PM2.5, PM10, NO2, CO, O3, SO2) caused air pollution (IFCsAP), Neural Comput.
