public sealed class FractionSplit : IMessage<FractionSplit>, IEquatable<FractionSplit>, IDeepCloneable<FractionSplit>, IBufferMessage, IMessage
Reference documentation and code samples for the Vertex AI v1beta1 API class FractionSplit.
Assigns the input data to training, validation, and test sets as per the
given fractions. Any of training_fraction, validation_fraction and
test_fraction may optionally be provided, they must sum to up to 1. If the
provided ones sum to less than 1, the remainder is assigned to sets as
decided by Vertex AI. If none of the fractions are set, by default roughly
80% of data is used for training, 10% for validation, and 10% for test.
