Application of Improved SAX Algorithm to QAR Flight Data
Physics Procedia, 2012 AbstractDuring describing, storing and retrieving such operations on QAR flight data, traditional SAX can’t overcome time series amplitude flex and timeline drift, so improved algorithm is proposed. QAR flight data will be divided into three stages and use algorithms to fill the cruise stage, thus allowing effective search for time series of different ...
