Enum Constant Detail

HE

public static final WeightInitScheme HE

As per He et al. (2015): Normal distribution with variance 2.0/nIn

ONES

public static final WeightInitScheme ONES

Weights are initialized with ones

XAVIER

public static final WeightInitScheme XAVIER

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

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))

ZEROS

public static final WeightInitScheme ZEROS

Weights are initialized with zeros

Method Detail

valueOf

public static WeightInitScheme valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

values

public static WeightInitScheme[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (WeightInitScheme c : WeightInitScheme.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared
