텐서플로우:: 작전:: 매트릭스 진단 부품
#include <array_ops.h> 배치 텐서의 배치 대각선 부분을 반환합니다.
요약
이 작업은 일괄 input 의 diagonal 부분이 포함된 텐서를 반환합니다. diagonal 부분은 다음과 같이 계산됩니다.
input k 차원 [I, J, K, ..., M, N] 있다고 가정하면 출력은 차원 [I, J, K, ..., min(M, N)] 갖는 k - 1 순위의 텐서입니다. [I, J, K, ..., min(M, N)] 어디:
diagonal[i, j, k, ..., n] = input[i, j, k, ..., n, n] .
입력은 최소한 행렬이어야 합니다.
예를 들어:
# 'input' is [[[1, 0, 0, 0]
[0, 2, 0, 0]
[0, 0, 3, 0]
[0, 0, 0, 4]],
[[5, 0, 0, 0]
[0, 6, 0, 0]
[0, 0, 7, 0]
[0, 0, 0, 8]]]and input.shape = (2, 4, 4)
tf.matrix_diag_part(input) ==> [[1, 2, 3, 4], [5, 6, 7, 8]]
which has shape (2, 4)
인수:
- 범위: 범위 개체
- 입력:
k >= 2 인 순위 k 텐서.
보고:
-
Output : diagonal.shape = input.shape[:-2] + [min(input.shape[-2:])] 모양을 갖는 추출된 대각선입니다.
