Beam transfer equipment (e.g. kicker magnets) has potentially significant impact on the global performance of a machine complex. Identifying root causes of malfunctions is currently tedious, and will become infeasible in future systems due to increasing complexity. Machine Learning could automate this process. For this purpose a collaboration between CERN and KU Leuven was established. We present an anomaly detection pipeline which includes preprocessing, detection, postprocessing and evaluation. Merging data of different, asynchronous sources is one of the main challenges. Currently, Gaussian Mixture Models and Isolation Forests are used as unsupervised detectors. To validate, we compare to manual e-logbook entries, which constitute a noisy ground truth. A grid search allows for hyper-parameter optimization across the entire pipeline. Lastly, we incorporate expert knowledge by means of semi-supervised clustering with COBRAS.</span> </td> </tr> <tr class="tablerow"> <td class="fieldkey">Paper</td> <td class="datarow">download <a href="https://jacow.org/icalepcs2019/papers/wempr010.pdf" target="pdf">WEMPR010.PDF</a> [0.450 MB / 5 pages]</td> </tr> <tr class="tablerow"> <td class="fieldkey">Export</td> <td class="datarow">download ※ <a href="../export/WEMPR010-bib.htm" target="exp">BibTeX</a> ※ <a href="../export/WEMPR010-tex.htm" target="exp"> LaTeX</a> ※ <a href="../export/WEMPR010-txt.htm" target="exp">Text/Word</a> ※ <a href="../export/WEMPR010-ris.htm" target="exp">RIS</a> ※ <a href="../export/WEMPR010.xml" target="exp">EndNote</a></td> </tr> <tr class="tablerow"> <td class="fieldgrp">Conference</td> <td class="fieldhigh"><a href="https://jacow.org/icalepcs2019/" target="pdf">ICALEPCS2019</a></td> </tr> <tr class="tablerow"> <td class="fieldkey">Series</td> <td class="datarow">International Conference on Accelerator and Large Experimental Physics Control Systems (17th)</td> </tr> <tr class="tablerow"> <td class="fieldkey">Location</td> <td class="datarow">New York, NY, USA</td> </tr> <tr class="tablerow"> <td class="fieldkey">Date</td> <td class="datarow">05-11 October 2019</td> </tr> <tr class="tablerow"> <td class="fieldgrp">Publisher</td> <td class="fieldhigh"><a href="https://jacow.org" target="pdf">JACoW Publishing, Geneva, Switzerland</a></td> </tr> <tr class="tablerow"> <td class="fieldkey">Editorial Board</td> <td class="datarow">Karen S.
