README.txt (this file) % Training Dataset (Matlab Format) % Training_dataset_15000AE_1000_samples.mat XTrain is in the format of 15000x1000 samples there are 15000 events (5000 are tensile, 5000 shear and 5000 mixed-events) each acoustic event is composed of 1000 time samples YTrain is the categorical array in the format of 15000x1 AE events are classified according to the following type: '1' = Tensile Mode '2' = Shear Mode '3' = Mixed-Mode freq is the vector of frequencies related to the given sampling frequency. It is composed of 501 elem(s) time is the time vector (sampling frequency has been reduced to 500kHz to save space). It is composed of 1000 elem(s) % Testing Dataset (Matlab Format) % Testing_dataset_1650AE_1000_samples.mat XTest is in the format of 1650x1000 samples there are 1650 total events for testing (550 are tensile, 550 shear and 550 mixed-events) each acoustic event is composed of 1000 time samples YTest is the categorical array in the format of 1650x1 AE events are classified according to the following type: '1' = Tensile Mode '2' = Shear Mode '3' = Mixed-Mode freq is the vector of frequencies related to the given sampling frequency.
