a data sample, can approximate the stochastic process that generated it. The methodology can be useful in many contexts where we need to share data while preserving user privacy. There are known literature for data generation based on Bayesian neural networks/hidden Markov models that are restricted to static and propositional data. We focus on time-evolving data and preference data. We will study essentially two aspects: (1) the generator to produce realistic data, having the same properties of the original one, and (2) we want to investigate how to inject drift within the data generation process in a controlled manner. The idea is to model the stochastic process through a dependency graph among random variables so that the drift can be simply modeled by changing the structure of the underlying graph through a morphing process.</span></p> <h4><b>Tangible Outcomes</b></h4> <ol> <li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">available on github – </span><a href="https://github.com/fsp22/mcd_dds4rs"><span style="font-weight: 400;">https://github.com/fsp22/mcd_dds4rs</span></a><span style="font-weight: 400;">聽</span></li> <li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">implementation of the model presented in the paper “Modelling Concept Drift in Dynamic Data Streams for Recommender Systems” </span><a href="https://github.com/fsp22/mcd_dds4rs"><span style="font-weight: 400;">https://github.com/fsp22/mcd_dds4rs</span></a><span style="font-weight: 400;">聽</span></li> </ol> </div> </div> </div> </div> </article> </div> </div>   <div class="footer"> <div class="container"> <div class="row"> <div class="col-xs-12 col-sm-12 col-md-12 logomark-row"> <div class="row center"> <div class="col-sm-6 col-lg-3"> <ul> <li class="consortium-logo"> <img src="https://www.humane-ai.eu/wp-content/themes/humaneai-child/img/k4all_100px.png" alt="IDRC Logo"> </li> <li class="with-icon"> <i class="icon-location hidden-xs hidden-sm hidden-md"></i> <h5><a href="https://www.k4all.org/"> Knowledge 4 All Foundation Ltd.</a> </h5> </li> <li>Betchworth House</li> <li>57-65 Station Road</li> <li>Redhill, Surrey, RH1 1DL</li> </ul> </div> <div class="col-sm-6 col-lg-6"> <h2>Humane AI on Social Media</h2> <ul class=""> <li style="padding-left: 4px;"><a href="https://twitter.com/humaneainet">Follow us on Twitter <i class="icon-right-open"></i></a></li> <li style="padding-left: 4px;"><a href="https://www.linkedin.com/company/90859893/admin/feed/posts/">Follow us on LinkedIn <i class="icon-right-open"></i></a></li> <li style="padding-left: 4px;"><a href="https://www.facebook.com/profile.php?id=100089945357753">Follow us on Facebook <i class="icon-right-open"></i></a></li> <li style="padding-left: 4px;"><a href="https://www.ai4europe.eu/ai-community/projects/humane-ai-net">Find us at AI4Europe <i class="icon-right-open"></i></a></li> </ul> </div> </div> <div class="row center eu-byline"> <div class="col-sm-6 col-md-2 col-lg-2 col-lg-offset-2 text-center"> <img style="margin-right: 0" src="https://www.humane-ai.eu/wp-content/themes/humaneai-child/img/eu.jpg" alt="EU Logo"/> </div> <div class="col-sm-6"> <p>This project has received funding from the European Union鈥檚 Horizon 2020 research and innovation programme under grant agreement No 952026.</p> </div> </div> </div> </div> <div class="row"> <div class="col-sm-12 text-center"> <a href="/eu/terms-of-service-and-privacy-policy/">Terms of Service & Privacy Policy</a> | © <a href="https://www.k4all.org/" target="_blank">Knowledge 4 All Foundation</a></div> </div> </div> </div> <script type="text/javascript" src="https://www.humane-ai.eu/wp-content/themes/openingup/js/script.min.js?ver=20201208" id="op-script-js"></script> <script type="text/javascript" src="https://stats.wp.com/e-202509.js" id="jetpack-stats-js" data-wp-strategy="defer"></script> <script type="text/javascript" id="jetpack-stats-js-after"> /* <![CDATA[ */ _stq = window._stq || []; _stq.push([ "view", JSON.parse("{\"v\":\"ext\",\"blog\":\"161946599\",\"post\":\"4688\",\"tz\":\"0\",\"srv\":\"www.humane-ai.eu\",\"j\":\"1:13.1.4\"}") ]); _stq.push([ "clickTrackerInit", "161946599", "4688" ]); /* ]]> */ </script> <script> (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); ga('create', 'UA-353712-25', 'auto'); ga('send', 'pageview', {'anonymizeIp': true}); </script> </body> </html>
