Usage

sax_via_window(ts, w_size, paa_size, a_size, nr_strategy, n_threshold)

Arguments

ts	the input timeseries.
w_size	the sliding window size.
paa_size	the PAA size.
a_size	the alphabet size.
nr_strategy	the Numerosity Reduction strategy, acceptable values are "exact" and "mindist" – any other value triggers no numerosity reduction.
n_threshold	the normalization threshold.
