RandomGamma

public final class RandomGamma

Outputs random values from the Gamma distribution(s) described by alpha.

This op uses the algorithm by Marsaglia et al. to acquire samples via transformation-rejection from pairs of uniform and normal random variables. See http://dl.acm.org/citation.cfm?id=358414

Constants

Constant Value: "RandomGamma"

Public Methods

public Output<U> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static RandomGamma<U> create (Scope scope, Operand<? extends TNumber> shape, Operand<U> alpha, Options... options)

Factory method to create a class wrapping a new RandomGamma operation.

Parameters

scope	current scope
shape	1-D integer tensor. Shape of independent samples to draw from each distribution described by the shape parameters given in alpha.
alpha	A tensor in which each scalar is a "shape" parameter describing the associated gamma distribution.
options	carries optional attributes values

Returns

• a new instance of RandomGamma

public Output<U> output ()

A tensor with shape `shape + shape(alpha)`. Each slice `[:, ..., :, i0, i1, ...iN]` contains the samples drawn for `alpha[i0, i1, ...iN]`. The dtype of the output matches the dtype of alpha.

public static RandomGamma.Options seed (Long seed)

Parameters

seed	If either `seed` or `seed2` are set to be non-zero, the random number generator is seeded by the given seed. Otherwise, it is seeded by a random seed.

public static RandomGamma.Options seed2 (Long seed2)

Parameters

seed2	A second seed to avoid seed collision.
