类 StringIndexerModel

java.lang.Object

org.apache.flink.ml.feature.stringindexer.StringIndexerModel

所有已实现的接口:

Serializable, org.apache.flink.ml.api.AlgoOperator<StringIndexerModel>, org.apache.flink.ml.api.Model<StringIndexerModel>, org.apache.flink.ml.api.Stage<StringIndexerModel>, org.apache.flink.ml.api.Transformer<StringIndexerModel>, org.apache.flink.ml.common.param.HasHandleInvalid<StringIndexerModel>, org.apache.flink.ml.common.param.HasInputCols<StringIndexerModel>, org.apache.flink.ml.common.param.HasOutputCols<StringIndexerModel>, StringIndexerModelParams<StringIndexerModel>, org.apache.flink.ml.param.WithParams<StringIndexerModel>

public class StringIndexerModel
extends Object
implements org.apache.flink.ml.api.Model<StringIndexerModel>, StringIndexerModelParams<StringIndexerModel>

A Model which transforms input string/numeric column(s) to double column(s) using the model data computed by StringIndexer.

The `keep` option of HasHandleInvalid means that we transform the invalid input into a special index, whose value is the number of distinct values in this column.
