| Class | Description |
|---|---|
| FlatToRelational |
A filter that converts a flat representation of multivariate time series to a relational representation.
|
| OneDimensionalTimeSeriesToString |
A filter to concatenate the string representations of data points of a one dimensional time series that are given
as values of a relational attribute (e.g., output of the SAXTransformer).
|
| PAATransformer |
A filter to perform the Piecewise Aggregate Approximation transformation to time series.
It uses the "N/n not equal an integer" generalization. |
| SAXTransformer |
A filter to perform the Symbolic Aggregate Approximation transformation to time series.
The filter can handle arbitrarily big alphabet sizes. For more information see: Jessica Lin, Eamonn Keogh, Stefano Lonardi, Bill Chiu: A Symbolic Representation of Time Series, with Implications for Streaming Algorithms. |
