Interface IPipelineCharacterizer

All Known Implementing Classes:

WEKAPipelineCharacterizer

public interface IPipelineCharacterizer

Finds patterns in given MLPipelines. A pipeline characterizer first has to be built with build(List), where it identifies patterns in the given data base of pipelines. Subsequently, it can be used to check for these patterns in a new pipeline.

Method Summary

Modifier and Type	Method and Description
void	build(java.util.List<MLPipeline> pipelines) Finds frequent patterns in the given list of pipelines.
double[]	characterize(MLPipeline pipeline) Checks which of the found patterns (found during the training phase in build(List)) occur in this pipeline.
double[][]	getCharacterizationsOfTrainingExamples() For each MLPipeline that was used in the training, return which found pattern (found during the training phase in build(List)) occurs in which pipeline.

Method Detail

build

void build(java.util.List<MLPipeline> pipelines)

Finds frequent patterns in the given list of pipelines.

Parameters:

pipelines - The pipelines to go though for patterns

characterize

double[] characterize(MLPipeline pipeline)

Checks which of the found patterns (found during the training phase in build(List)) occur in this pipeline. If in the returned list l, l[j]=1, pattern p occurs in this pipeline. Otherwise l[j] and pattern j doesn't occur in this pipeline.

Parameters:

pipeline - The pipeline for which pattern occurrence is checked

Returns:

A list representing pattern occurrences in the pipeline

getCharacterizationsOfTrainingExamples

double[][] getCharacterizationsOfTrainingExamples()

For each MLPipeline that was used in the training, return which found pattern (found during the training phase in build(List)) occurs in which pipeline. If in the returned matrix m, m[i][j]=1, pattern p occurs in training pipeline i. Otherwise m[i][j] and pattern j doesn't occur in training pipeline i.

Returns:

A matrix representing pattern occurrences in pipelines
