Overview / Discretization parameter optimization

Discretization parameter optimization

Automated selection of SAX window / PAA / alphabet via a grammar-reduction heuristic.

This module discusses the SAX discretization parameter optimization approach implemented in GrammarViz 3.0 — a tutorial for the GUI sampler, and the theory behind its grammar-reduction objective.
