텐서플로우:: 작전:: 랜덤포아송V2
#include <random_ops.h>
비율로 설명되는 포아송 분포에서 임의의 값을 출력합니다.
요약
이 작업은 속도에 따라 두 가지 알고리즘을 사용합니다. rate >= 10이면 Hormann의 알고리즘을 사용하여 변환 거부를 통해 샘플을 획득합니다. http://www.sciencedirect.com/science/article/pii/0167668793909974를 참조하세요.
그렇지 않으면 Knuth의 알고리즘을 사용하여 균일 확률 변수를 곱하여 샘플을 얻습니다. Donald E. Knuth(1969)를 참조하십시오. 반수치 알고리즘. 컴퓨터 프로그래밍 기술, 2권. 애디슨 웨슬리
인수:
- 범위: 범위 개체
- 모양: 1차원 정수 텐서. 비율로 주어진 모양 매개변수에 의해 설명되는 각 분포에서 추출할 독립 표본의 모양입니다.
- rate: 각 스칼라가 관련 포아송 분포를 설명하는 "rate" 매개변수인 텐서입니다.
선택적 속성( Attrs
참조):
- Seed:
seed
또는 seed2
0이 아닌 값으로 설정된 경우 난수 생성기는 지정된 시드에 의해 시드됩니다. 그렇지 않으면 무작위 시드에 의해 시드됩니다. - Seed2: 시드 충돌을 피하기 위한 두 번째 시드입니다.

If rate \\\u003e= 10, then the algorithm by Hormann is used to acquire samples via transformation-rejection. See \u003chttp://www.sciencedirect.com/science/article/pii/0167668793909974\u003e.\n\nOtherwise, 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\n\nArguments:\n\n- scope: A [Scope](/versions/r1.15/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- shape: 1-D integer tensor. Shape of independent samples to draw from each distribution described by the shape parameters given in rate.\n- rate: A tensor in which each scalar is a \"rate\" parameter describing the associated poisson distribution.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r1.15/api_docs/cc/struct/tensorflow/ops/random-poisson-v2/attrs#structtensorflow_1_1ops_1_1_random_poisson_v2_1_1_attrs)):\n\n- 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.\n- seed2: A second seed to avoid seed collision.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r1.15/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): A tensor with shape `shape + shape(rate)`. Each slice `[:, ..., :, i0, i1, ...iN]` contains the samples drawn for `rate[i0, i1, ...iN]`.\n\n\u003cbr /\u003e\n\n| ### Constructors and Destructors ||\n|---|---|\n|
