类 VarianceThresholdSelector

java.lang.Object

org.apache.flink.ml.feature.variancethresholdselector.VarianceThresholdSelector

所有已实现的接口:

Serializable, org.apache.flink.ml.api.Estimator<VarianceThresholdSelector,VarianceThresholdSelectorModel>, org.apache.flink.ml.api.Stage<VarianceThresholdSelector>, org.apache.flink.ml.common.param.HasInputCol<VarianceThresholdSelector>, org.apache.flink.ml.common.param.HasOutputCol<VarianceThresholdSelector>, VarianceThresholdSelectorModelParams<VarianceThresholdSelector>, VarianceThresholdSelectorParams<VarianceThresholdSelector>, org.apache.flink.ml.param.WithParams<VarianceThresholdSelector>

public class VarianceThresholdSelector
extends Object
implements org.apache.flink.ml.api.Estimator<VarianceThresholdSelector,VarianceThresholdSelectorModel>, VarianceThresholdSelectorParams<VarianceThresholdSelector>

An Estimator which implements the VarianceThresholdSelector algorithm. The algorithm removes all low-variance features. Features with a variance not greater than the threshold will be removed. The default is to keep all features with non-zero variance, i.e. remove the features that have the same value in all samples.
