Enum Class WeightInitScheme

java.lang.Object
java.lang.Enum<WeightInitScheme>
oracle.pgx.config.mllib.WeightInitScheme
All Implemented Interfaces:
Serializable, Comparable<WeightInitScheme>, Constable
public enum WeightInitScheme extends Enum<WeightInitScheme>
Initialization scheme used for weights

  • Enum Constant Details

    • ZEROS

      public static final WeightInitScheme ZEROS
      Weights are initialized with zeros

    • ONES

      public static final WeightInitScheme ONES
      Weights are initialized with ones

    • XAVIER_UNIFORM

      public static final WeightInitScheme XAVIER_UNIFORM
      As per Glorot and Bengio (2010): Uniform distribution U(-s,s) with s = sqrt(6/(fanIn + fanOut))

    • HE

      public static final WeightInitScheme HE
      As per He et al. (2015): Normal distribution with variance 2.0/nIn

    • XAVIER

      public static final WeightInitScheme XAVIER
      As per Glorot and Bengio (2010): Gaussian distribution with mean 0, variance 2.0/(fanIn + fanOut)

  • Method Details

    • values

      public static WeightInitScheme[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static WeightInitScheme valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
