Constructor Detail

UniformFrequencyDiscretizer

public UniformFrequencyDiscretizer(Discretizer.Mode mode,
                                   int range)

Constructor of UniformDiscretizer which setup the mode and the range of discretization without preprocessing

Parameters:

mode - The mode of discretization column/row wise or by using the whole matrix

range - The number of value between min/max values of each row/column

UniformFrequencyDiscretizer

public UniformFrequencyDiscretizer(Discretizer.Mode mode,
                                   int range,
                                   boolean preprocess)

Constructor of UniformDiscretizer which setup the mode and the range of discretization

Parameters:

mode - The mode of discretization column/row wise or by using the whole matrix

range - The number of value between min/max values of each row/column

specify - if the method has to preprocess (compute measure before normalization, required for GLOBAL Mode)

Method Detail
