tensorflow::ops::RandomPoissonV2
#include <random_ops.h>
Outputs random values from the Poisson distribution(s) described by rate.
Summary
This op uses two algorithms, depending on rate. If rate >= 10, then the algorithm by Hormann is used to acquire samples via transformation-rejection. See http://www.sciencedirect.com/science/article/pii/0167668793909974.
Otherwise, Knuth's algorithm is used to acquire samples via multiplying uniform random variables. See Donald E. Knuth (1969). Seminumerical Algorithms. The Art of Computer Programming, Volume 2. Addison Wesley
Arguments:
- scope: A Scope object
- shape: 1-D integer tensor. Shape of independent samples to draw from each distribution described by the shape parameters given in rate.
- rate: A tensor in which each scalar is a "rate" parameter describing the associated poisson distribution.
Optional attributes (see Attrs):
- 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.
- seed2: A second seed to avoid seed collision.
Returns:
Output: A tensor with shape shape + shape(rate). Each slice [:, ..., :, i0, i1, ...iN] contains the samples drawn for rate[i0, i1, ...iN].
