텐서플로우:: 작전:: ComputeAccidentalHits
#include <candidate_sampling_ops.h>
true_labels와 일치하는 samplingd_candidates의 위치 ID를 계산합니다.
요약
로그 확률 NCE를 수행할 때 이 작업의 결과는 SparseToDense 작업을 통해 전달된 다음 샘플링된 후보의 로짓에 추가되어야 합니다. 이는 분류기가 샘플링된 레이블임을 확인함으로써 실제 레이블과 일치하는 샘플링된 레이블을 '제거'하는 효과가 있습니다.
인수:
- 범위: 범위 개체
- true_classes: UnpackSparseLabels의 true_classes 출력입니다.
- Sampled_candidates: CandidateSampler의 samplingd_candidates 출력입니다.
- num_true: 컨텍스트당 실제 레이블 수입니다.
선택적 속성( Attrs
참조):
- Seed: Seed 또는 Seed2가 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.
보고:
-
Output
인덱스: true_candidates의 행에 해당하는 인덱스 벡터입니다. -
Output
ID: 인덱스의 해당 인덱스가 있는 행의 true_label과 일치하는 samplingd_candidates의 위치 ID 벡터입니다. -
Output
가중치: 인덱스 및 ID와 동일한 길이의 벡터로, 각 요소는 -FLOAT_MAX입니다.

This has the effect of 'removing' the sampled labels that match the true labels by making the classifier sure that they are sampled labels.\n\nArguments:\n\n- scope: A [Scope](/versions/r1.15/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- true_classes: The true_classes output of UnpackSparseLabels.\n- sampled_candidates: The sampled_candidates output of CandidateSampler.\n- num_true: Number of true labels per context.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r1.15/api_docs/cc/struct/tensorflow/ops/compute-accidental-hits/attrs#structtensorflow_1_1ops_1_1_compute_accidental_hits_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: An 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) indices: A vector of indices corresponding to rows of true_candidates.\n- [Output](/versions/r1.15/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output) ids: A vector of IDs of positions in sampled_candidates that match a true_label for the row with the corresponding index in indices.\n- [Output](/versions/r1.15/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output) weights: A vector of the same length as indices and ids, in which each element is -FLOAT_MAX.\n\n\u003cbr /\u003e\n\n| ### Constructors and Destructors ||\n|---|---|\n|
