Interface TransformStatistics

All Known Implementing Classes:

SimpleTransform

public interface TransformStatistics

An interface for the statistics that need to be collected for a specific Transformation on a single feature.

TransformStatistics are purely a runtime collection, they should not be persisted, nor can be directly constructed.

Method Summary

Modifier and Type	Method and Description
Transformer	generateTransformer() Generates the appropriate Transformer from the collected statistics.
void	observeSparse() Observes a sparse (i.e., zero) value.
void	observeSparse(int count) Observes count sparse values.
void	observeValue(double value) Observes a value and updates the statistics.

observeSparse

void observeSparse(int count)

Observes count sparse values.

Parameters:

count - The number of sparse values.

generateTransformer

Transformer generateTransformer()

Generates the appropriate Transformer from the collected statistics.
