ACCELERATED PATTERN RECOGNITION IN ACTION SPORTS

Systems and techniques for accelerated pattern matching in action sports are described herein. A plurality of data sets may be collected from a data stream received from a sensor array. Each data set of the plurality of data sets may be compressed into a magnitude value. A first mean and a first standard deviation may be determined for a first set of magnitude values corresponding to a first time period. A second mean and a second standard deviation may be determined for a second set of magnitude values corresponding to a second time period. A mean ratio may be calculated for the first mean and the second mean and a standard deviation ratio may be calculated for the first standard deviation and the second standard deviation. A start point for an action may be generated by determining that the mean ratio and the standard deviation ratio are outside a threshold.
