Shapelet
This extension enables user to apply Shapelet analysis on their time series data. For more information see X. Renard, M. Rifqi, G. Fricout, M.

The basic idea of Shapelets is, that from a collection of batches of
time series, subsequences are randomly drawn. These Shapelet
candidates are than used to perform a feature transformation on
different time series. The Shapelet is compared with the time series
of the new data and the minimal distance of the Shapelet candidate and
the time series is calculated. If the minimal distances for many
batches are small, the Shapelet can be considered to occur often in
the time series and is representable as a subsequence.
The
distances can also be different for different kind of batches
(different labeled batches). So the calculated features may be
suitable for a classification of the batches.
Please have a look into the tutorial processes of the operators to
get an impression how to configure them.
The extension contains
the following operators:
- Create Searchspace:
- used to draw the Shapelet candidates from a collection of batches. Delivers a Shapelet Model.
- Shapelet Transformation:
- used to calculate the distance features by applying the Shapelet model on a collection of batches.
- Shapelet Model to ExampleSet:
- used to convert a Shapelet Model to an ExampleSet, with the attributes containing the values of the Shapelets.
- Select Shapelets by Weight:
- used to select only the most relevant Shapelets from a Shapelet Model.
