Symbolic Aggregation Approximation (SAX)

Uses Symbolic Aggregation Approximation to reduce the output space into a (small) set of symbols. The input values are replaced by the value of the bin that they match. Each bin’s value corresponds to one letter or digit. This generates a string from the input values. The final output is generated by sliding a window over this string.
