I am currenlty working in industrial projects concering using data mining and machine learning at SICS, but I have also been PhD student at Mälardalen University within the research school ITSEASY, working with fault diagnostics and prognostics. I defended my PhD thesis Nov. 10, 2015.
I have previously been involved in a project were we were developing an intrusion detection and active response system using a statistical anomaly detection and clustering algorithm, and an intrusion consequence analyzer for triggering responses.

Presentation: "Fault Detection and Diagnosis using Statistical Machine Learning and Case-Based Reasoning" Speaker: Tomas Olsson A workshop about the most recent research in Artificial Intelligence organized by Swedish Technion Society and Västerås Science Park, February 8, 2016, 8:30-17:00 Program and registration are available at http://technionsts.se/?page_id=89
A Data-Driven Approach to Remote Fault Diagnosis of Heavy-duty Machines On Nov 10, Tomas Olsson successfully defended his doctoral thesis at Mälardalen University Collage. The faculty examiner was Docent Amy Loutfi, Örebro University. The examining committee consisted of Professor Henrik Boström, Stockholm University; Professor Maria Lindén, MDH; Professor Niklas Lavesson, Blekinge Institute of Technology. Abstract Heavy-duty machines are equipment constructed for working under rough...
