Statistical and machine learning methods for Sensor Data

Sensor data are multidimensional streams of observations from various sensor systems. We work mainly on sensor systems in the maritime and industrial sector with a particular interest on fault/anomaly/change detection.

About the project

For maritime safety surveillance we develop new approaches based on the availability of large arrays of sensors, which monitor condition and performance of vessels, machinery, or power systems. Sensor data are becoming increasingly available on global ship fleets, with efficient broadband connectivity to shore. We suggest new generic approaches to condition and/or performance monitoring, which is the process of identifying changes in sensor data that are indicative of a developing anomaly or fault. In addition to using previous failure data and pattern recognition techniques to detect anomalies, we test model-based approaches that exploit knowledge on the sensors and the conditions they assess. We also rely on other data sources such as AIS data for the study of manoeuvres and collision avoidance.
