In the past, the recorded time series were often evaluated manually or by simple heuristics (such as threshold values) to detect abnormal behavior. With the more recent advances in the fields of <strong>ML (machine learning)<\/strong> and <strong>AI (articial intelligence)<\/strong>, ML-based anomaly detection algorithms are becoming increasingly popular for many tasks such as health monitoring or predictive maintenance.<\/p>\n<p>In our research group we develop new <strong>unsupervised<\/strong> anomaly detection approaches. Methods and algorithms that we use are (among others) <strong>TCN<\/strong> (Temporal Coherence Networks), <strong>LSTM<\/strong> (Long Short-Term Memory) and <strong>wavelets<\/strong>.<\/p>\n<p><strong>Application areas<\/strong>: predictive maintenance, health services, ECG.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Project members<\/strong><\/p>\n<table border=\"0\" cellspacing=\"1\" cellpadding=\"1\">\n<tbody>\n<tr>\n<td>\n<table border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td><a class=\"thickbox\" href=\"http:\/\/blogs.gm.fh-koeln.de\/ciop\/files\/2015\/03\/markus.thill_.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1154 alignleft\" src=\"http:\/\/blogs.gm.fh-koeln.de\/ciop\/files\/2015\/03\/markus.thill_-293x300.jpg\" alt=\"\" width=\"190\" height=\"195\" srcset=\"https:\/\/blogs.gm.fh-koeln.de\/ciop\/files\/2015\/03\/markus.thill_-293x300.jpg 293w, https:\/\/blogs.gm.fh-koeln.de\/ciop\/files\/2015\/03\/markus.thill_.jpg 313w\" sizes=\"auto, (max-width: 190px) 100vw, 190px\" \/><\/a><\/td>\n<\/tr>\n<tr>\n<td><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/td>\n<td><a href=\"http:\/\/blogs.gm.fh-koeln.de\/ciop\/about\/people-2\/\">Markus Thill<\/a>,<br \/>\nTH K\u00f6ln<\/td>\n<td><a class=\"thickbox\" href=\"http:\/\/blogs.gm.fh-koeln.de\/konen\/files\/2014\/08\/konen-3.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1298 alignleft\" src=\"http:\/\/blogs.gm.fh-koeln.de\/konen\/files\/2014\/08\/konen-3-249x300.jpg\" alt=\"konen-3\" width=\"151\" height=\"182\" \/><\/a><\/td>\n<td><a href=\"http:\/\/blogs.gm.fh-koeln.de\/ciop\/about\/people-2\/\">Prof. Dr. Wolfgang Konen<\/a>,<br \/>\nTH K\u00f6ln<\/td>\n<\/tr>\n<tr>\n<td><\/td>\n<td><\/td>\n<td colspan=\"2\">\n<h2><\/h2>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<h2><strong>Honors<\/strong><\/h2>\n<ul>\n<li><a href=\"http:\/\/blogs.gm.fh-koeln.de\/ciop\/2019\/11\/13\/ad-lstm-paper-wins-the-best-paper-award\/\">PhD Candidate from CIOP Group Wins Best Paper Award<\/a><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><strong>Publications<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<div class=\"teachpress_pub_list\"><form name=\"tppublistform\" method=\"get\"><a name=\"tppubs\" id=\"tppubs\"><\/a><\/form><div class=\"teachpress_publication_list\"><h3 class=\"tp_h3\" id=\"tp_h3_2021\">2021<\/h3><div class=\"tp_publication tp_publication_article\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\"> Thill, Markus;
