jMotif

Time series mining with symbolic discretization — SAX, grammar inference, and interpretable classification.

• SAX-VSM Interpretable time series classification with SAX and a tf·idf vector space model — the project site, with an algorithm primer.
• jmotif-sax Java implementation of SAX, HOT-SAX discord discovery, and EMMA motif discovery.
• jmotif-gi Sequitur and Re-Pair grammar induction over SAX word sequences.
• sax-vsm_classic The SAX-VSM classifier reference implementation (Java, Maven Central).
• jmotif-R The stack in R with C++/Rcpp internals — on CRAN.
• saxpy The stack in Python — on PyPI.
• GrammarViz Sister project: interactive variable-length motif and anomaly discovery via grammar inference.
