13th Meeting of Researchers in Biometrics/Statistics
11th SCHOOL OF BIOMETRICS
SCHOOL OF BIOMETRICS Topic
Analyzing On-line monitoring data from Intensive Care Alarm Systems
SCHOOL OF BIOMETRICS Invited Speaker
We discuss filtering procedures for robust extraction of a signal from noisy time series as they occur in monitoring of vital parameters in intensive care. Moving averages and running medians are standard approaches to this, but they have shortcomings when large spikes (outliers) respectively trends occur. Modified trimmed means and linear median hybrid filters have been designed to combine advantages of both approaches, but they do not completely overcome the difficulties. Improvements can be achieved by methods of robust regression, which are applicable even in real time because of increased computational power and faster algorithms. Reviewing and extending recent work we present methods for robust online signal extraction and discuss their merits for preserving trends, abrupt shifts and extremes and for the removal of spikes.
