jmotif: Time Series Analysis Toolkit Based on Symbolic Aggregate Dicretization, i.e. SAX

Implements time series z-normalization, SAX, HOT-SAX, VSM, SAX-VSM, RePair, and RRA algorithms facilitating time series motif (i.e., recurrent pattern), discord (i.e., anomaly), and characteristic pattern discovery along with interpretable time series classification.
