tensor akışı:: işlem:: MatrixDiag
#include <array_ops.h> Belirli bir toplu diyagonal değerlere sahip toplu bir diyagonal tensör döndürür.
Özet
Bir diagonal verildiğinde, bu işlem diagonal bir tensör döndürür ve diğer her şey sıfırlarla doldurulur. Köşegen şu şekilde hesaplanır:
diagonal k boyutu olduğunu varsayalım [I, J, K, ..., N] , bu durumda çıktı k+1 dereceli ve [I, J, K, ..., N, N]` boyutlarına sahip bir tensör olur; burada:
output[i, j, k, ..., m, n] = 1{m=n} * diagonal[i, j, k, ..., n] .
Örneğin:
# 'diagonal' is [[1, 2, 3, 4], [5, 6, 7, 8]]
and diagonal.shape = (2, 4)
tf.matrix_diag(diagonal) ==> [[[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]]]which has shape (2, 4, 4)
Argümanlar:
- kapsam: Bir Kapsam nesnesi
- diyagonal: Derece
k , burada k >= 1 .
İade:
-
Output : Rank k+1 , output.shape = diagonal.shape + [diagonal.shape[-1]] ile.
