The easiest way to use ESCAPE is to use the ESCAPE.py script. To do this, simply run the script from the same location as the cURL file, or us the -c flag to point to the file. The script will then download all the data, and proceed with KL classification and then HMM modelling of the audio files that have been manually tagged. The script will generate a PCA plot of the first three principal components of the manually tagged data.
