   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Marcus Jirwe; [2021]
   Keywords : Predictive maintenance; Anomaly detection; Online learning; Edge environment; Receiver Operating Characteristic curve; Förebyggande underhåll; anomalidetektering; sekventiell inlärning; nätverkskanten; ”Receiver Operating Characterstic”-kurva;

   Abstract : The society of today relies a lot on the industry and the automation of factory tasks is more prevalent than ever before. However, the machines taking on these tasks require maintenance to continue operating. This maintenance is typically given periodically and can be expensive while sometimes requiring expert knowledge. READ MORE

3. 17. EVALUATION OF UNSUPERVISED MACHINE LEARNING MODELS FOR ANOMALY DETECTION IN TIME SERIES SENSOR DATA

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Lorenzo Bracci; Amirhossein Namazi; [2021]
   Keywords : Machine learning; Unsupervised learning; Anomaly detection; Time Series data; Maskininlärning; Oövervakat Lärande; Anomalidetektering; tidsseriedata;

   Abstract : With the advancement of the internet of things and the digitization of societies sensor recording time series data can be found in an always increasing number of places including among other proximity sensors on cars, temperature sensors in manufacturing plants and motion sensors inside smart homes. This always increasing reliability of society on these devices lead to a need for detecting unusual behaviour which could be caused by malfunctioning of the sensor or by the detection of an uncommon event.
