discretize

public List<Interval<Double>> discretize(Iterable<Double> unsortedData,
                                         DiscretizationOptions options,
                                         String dataColumn)

Discretizes unsorted continuous data that may contain missing (null) values.

Specified by:

discretize in interface Discretize

Parameters:

unsortedData - The data to discretize.

options - Options that affect how discretization is performed, such as the algorithm to use.

dataColumn - The name of the source column. This is only used for error reporting.

Returns:

A number of bins each identified by an interval.

discretize

public List<DiscretizationInfo> discretize(DataReaderCommand dataReaderCommand,
                                           List<DiscretizationColumn> dataColumns,
                                           DiscretizationAlgoOptions options)

Discretizes one or more data columns, that may contain missing (null) values.

Specified by:

discretize in interface Discretize

Parameters:

dataReaderCommand - The data reader command to allow iteration of data.

dataColumns - The data columns that should be discretized and options per column.

options - Options governing the overall discretization algorithm. Each data column also has options.

Returns:

A number of bins each identified by an interval for each data column.

discretizeWeighted

public List<Interval<Double>> discretizeWeighted(Iterable<WeightedValue> unsortedData,
                                                 DiscretizationOptions options,
                                                 String dataColumn)

Discretizes unsorted weighted continuous data that may contain missing (null) values.

Specified by:

discretizeWeighted in interface Discretize

Parameters:

unsortedData - The weighted data to discretize.

options - Options that affect how discretization is performed, such as the algorithm to use.

dataColumn - The name of the source column. This is only used for error reporting.

Returns:

A number of bins each identified by an interval.
