Outputs random values from the Gamma distribution(s) described by alpha.
tf.raw_ops.RandomGamma( shape, alpha, seed=0, seed2=0, name=None )
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
Args | |
---|---|
shape | A Tensor . Must be one of the following types: int32 , int64 . 1-D integer tensor. Shape of independent samples to draw from each distribution described by the shape parameters given in alpha. |
alpha | A Tensor . Must be one of the following types: half , float32 , float64 . A tensor in which each scalar is a "shape" parameter describing the associated gamma distribution. |
seed | An optional int . Defaults to 0 . 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. |
seed2 | An optional int . Defaults to 0 . A second seed to avoid seed collision. |
name | A name for the operation (optional). |
Returns | |
---|---|
A Tensor . Has the same type as alpha . |
