Abstract

In this work we investigate the use of a fuzzy inspired ap- proach for anomaly detection in different electromagnetic time series datasets. The method proposed uses simple methods in a serialized way to achieve anomaly detection. Each method is a smaller component of the system. Each of them adds an element towards the anomaly detection: A smoothing filter removes any unwanted noise, an automated peak finding with Fast Fourier Transformation and correlation reduces the dimension- ality of the signal, a fuzzy inference system encodes the signal before the final comparison and respective output. The proposed method is evalu- ated in 5 benchmark datasets with promising results and the F-Score is used to demonstrate its performance. The method is also evaluated in real datasets gathered from the SWARM satellites for the detection of possible anomalies prior and post to a seismic event. The preliminary experimental results prove to be promising for the proposed method for the detection of anomalies in electromagnetic time series datasets.
