1. 1. Time Series Anomaly Detection in Radio Test

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Yu Zhu; [2023]
   Keywords : ;

   Abstract : Production tests evaluate products with automated systems enabling swift data collection, while anomaly detection in the gathered data is widely employed in industries for damage prediction and issue prevention. Ericsson, a leader in the telecommunications industry, has a Temperature Quality Test (TQT) platform which involves precise performance measurements on radios, gathering abundant data in both single value and time series formats to evaluate and improve tested products.

5. 4. Detecting anomalies in data streams driven by ajump-diffusion process

   University essay from Umeå universitet/Institutionen för fysik

   Author : Carl Paulin; [2021]
   Keywords : machine learning; ML; random forest; anomaly; detection; outlier; analysis; financial modelling; merton; jump-diffusion process; stochastic process; isolation forest; IF; robust random cut forest; RRCF;

   Abstract : Jump-diffusion processes often model financial time series as they can simulate the random jumps that they frequently exhibit. These jumps can be seen as anomalies and are essential for financial analysis and model building, making them vital to detect. READ MORE

6. 5. Detection of Long Term Vibration Deviations in GasTurbine Monitoring Data

   University essay from Linköpings universitet/Fordonssystem

   Author : Johan Hansson; [2020]
   Keywords : Machine Learning; Vibrations;

   Abstract : Condition based monitoring is today essential for any machine manufacturer tobe able to detect and predict faults in their machine fleet. This reduces the maintenancecost and also reduces machine downtime. READ MORE
