Class StratifiedSplit

  • All Implemented Interfaces:
    StratifiedSplitOrBuilder, com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, Serializable

    public final class StratifiedSplit
    extends com.google.protobuf.GeneratedMessageV3
    implements StratifiedSplitOrBuilder
     Assigns input data to the training, validation, and test sets so that the
     distribution of values found in the categorical column (as specified by the
     `key` field) is mirrored within each split. The fraction values determine
     the relative sizes of the splits.
    
     For example, if the specified column has three values, with 50% of the rows
     having value "A", 25% value "B", and 25% value "C", and the split fractions
     are specified as 80/10/10, then the training set will constitute 80% of the
     training data, with about 50% of the training set rows having the value "A"
     for the specified column, about 25% having the value "B", and about 25%
     having the value "C".
    
     Only the top 500 occurring values are used; any values not in the top
     500 values are randomly assigned to a split. If less than three rows contain
     a specific value, those rows are randomly assigned.
    
     Supported only for tabular Datasets.
