abstract class SequenceEstimator[I <: FeatureType, O <: FeatureType] extends Estimator[SequenceModel[I, O]] with OpPipelineStageN[I, O]

Takes a sequence of input features of the same type and performs a fit operation in order to define a transformation for those (or similar) features. This abstract class should be extended when settable parameters are needed within the fit function

I

input feature type

O

output feature type

    This method is used to make a copy of the instance with new parameters in several methods in spark internals Default will find the constructor and make a copy for any class (AS LONG AS ALL CONSTRUCTOR PARAMS ARE VALS, this is why type tags are written as implicit vals in base classes).

    This method is used to make a copy of the instance with new parameters in several methods in spark internals Default will find the constructor and make a copy for any class (AS LONG AS ALL CONSTRUCTOR PARAMS ARE VALS, this is why type tags are written as implicit vals in base classes).

    Note: that the convention in spark is to have the uid be a constructor argument, so that copies will share a uid with the original (developers should follow this convention).

    returns
