tensoreflusso:: ops:: Diag
#include <array_ops.h> Restituisce un tensore diagonale con determinati valori diagonali.
Riepilogo
Data una diagonal , questa operazione restituisce un tensore con la diagonal e tutto il resto riempito con zeri. La diagonale si calcola come segue:
Assumendo che diagonal abbia dimensioni [D1,..., Dk], allora l'output è un tensore di rango 2k con dimensioni [D1,..., Dk, D1,..., Dk] dove:
output[i1,..., ik, i1,..., ik] = diagonal[i1, ..., ik] e 0 ovunque.
Per esempio:
# 'diagonal' is [1, 2, 3, 4]
tf.diag(diagonal) ==> [[1, 0, 0, 0]
[0, 2, 0, 0]
[0, 0, 3, 0]
[0, 0, 0, 4]] Argomenti:
- scope: un oggetto Scope
- diagonale: tensore di rango k dove k è al massimo 1.
Resi:
-
Output : il tensore di uscita.
