tensoreflusso:: ops:: MaxPoolGradV2
#include <nn_ops.h> Calcola i gradienti della funzione maxpooling.
Riepilogo
Argomenti:
- scope: un oggetto Scope
- orig_input: il tensore di input originale.
- orig_output: il tensore di output originale.
- grado: 4-D. I gradienti rappresentano l'output di
max_pool . - ksize: la dimensione della finestra per ciascuna dimensione del tensore di input.
- passi: il passo della finestra scorrevole per ogni dimensione del tensore di input.
- riempimento: il tipo di algoritmo di riempimento da utilizzare.
Attributi facoltativi (vedi Attrs ):
- data_format: specifica il formato dei dati di input e output. Con il formato predefinito "NHWC", i dati vengono archiviati nell'ordine di: [batch, in_height, in_width, in_channels]. In alternativa, il formato potrebbe essere "NCHW", l'ordine di archiviazione dei dati di: [batch, in_channels, in_height, in_width].
Resi:
-
Output : i gradienti corrispondono all'input in max_pool .
