METHOD AND SYSTEM FOR EXTRACTING FEATURES FOR USE IN EMBEDDED ARTIFICIAL INTELLIGENCE MECHANISMS

Method and system for utilizing sequential input inertial sensor data to calculate recursive features for training a machine learning algorithm or for classifying the data as a known class. The recursive feature values of a current data sample are calculating based on comparisons between the current data sample value and previous recursive feature values. The recursive features include a recursive maximum, recursive minimum, recursive peak to peak, recursive average, recursive root mean square, and recursive variance.
