Special Issue Information

Dear Colleagues,

With the rapid development of sensing technology, a large volume of time series data has been collected, often by several sensors, in diverse applications such as financial markets, weather forecasting, utility demand prediction, fault detection in manufacturing, agriculture applications, and health monitoring. As time series data contains valuable, but often hidden, information, it is important to process it by exploiting data analytics, signal processing, and machine learning. Therefore, it is timely to report on the recent progress in time series analysis in sensor fusion.

This Special Issue aims to present recent advances in time series analysis in sensor fusion. It will include, but is not limited to, papers discussing time series with multiple sensors relating the following topics:

  • Novel methods for combining data from multiple sensors;
  • Machine learning and statistical techniques;
  • Signal processing techniques;
  • Feature extraction and selection;
  • Temporal alignment and calibration;
  • Time series forecasting and prediction;
  • Anomaly detection and fault diagnosis;
  • Data fusion for localization and tracking;
  • Application-specific studies;
  • Privacy and security considerations.

Due to connectivity and automation trends, the medical device industry is experiencing increased demand for safety and security mechanisms. Anomaly detection has proven to be a valuable approach for ensuring safety and security in other industries, such as automotive or IT. Medical devices must operate across a wide range of values due to variations in patient anthropometric data, making anomaly detection based on a simple threshold for signal deviations impractical. For example, surgical robots directly contacting the patient’s tissue require precise sensor data. However, since the deformation of the patient’s body during interaction or movement is highly dependent on body mass, it is impossible to define a single threshold for implausible sensor data that applies to all patients. This also involves statistical methods, such as Z-score, that consider standard deviation. Even pure machine learning algorithms cannot be expected to provide the required accuracy simply due to the lack of available training data. This paper proposes using hybrid filters by combining dynamic system models based on expert knowledge and data-based models for anomaly detection in an operating room scenario. This approach can improve detection performance and explainability while reducing the computing resources needed on embedded devices, enabling a distributed approach to anomaly detection.
