#include <nn_ops.h> Calcola i gradienti di convoluzione rispetto all'input.
Riepilogo
Argomenti:
- scope: un oggetto Scope
- input_sizes: un vettore intero che rappresenta la forma di
input , dove input è un tensore 4-D [batch, height, width, channels] . - filter: 4-D con forma
[filter_height, filter_width, in_channels, out_channels] . - out_backprop: 4-D con forma
[batch, out_height, out_width, out_channels] . I gradienti rappresentano l'output della convoluzione. - passi: il passo della finestra scorrevole per ogni dimensione dell'input della convoluzione. Deve essere nello stesso ordine della dimensione specificata con format.
- riempimento: il tipo di algoritmo di riempimento da utilizzare.
Attributi facoltativi (vedi Attrs ):
- esplicitamente_paddings: se
padding è "EXPLICIT" , l'elenco degli importi di riempimento espliciti. Per la i-esima dimensione, la quantità di riempimento inserita prima e dopo la dimensione è rispettivamente explicit_paddings[2 * i] e explicit_paddings[2 * i + 1] . Se padding non è "EXPLICIT" , explicit_paddings deve essere vuoto. - 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].
- dilatazioni: tensore 1-D di lunghezza 4. Il fattore di dilatazione per ciascuna dimensione di
input . Se impostato su k > 1, ci saranno k-1 celle saltate tra ciascun elemento filtro su quella dimensione. L'ordine delle dimensioni è determinato dal valore di data_format , vedi sopra per i dettagli. Le dilatazioni delle dimensioni del lotto e della profondità devono essere pari a 1.
Resi:
-
Output : 4-D con forma [batch, in_height, in_width, in_channels] . Gradiente rispetto all'input della convoluzione.

Gradients w.r.t. the output of the convolution.\n- strides: The stride of the sliding window for each dimension of the input of the convolution. Must be in the same order as the dimension specified with format.\n- padding: The type of padding algorithm to use.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r2.0/api_docs/cc/struct/tensorflow/ops/conv2-d-backprop-input/attrs#structtensorflow_1_1ops_1_1_conv2_d_backprop_input_1_1_attrs)):\n\n- explicit_paddings: If `padding` is `\"EXPLICIT\"`, the list of explicit padding amounts. For the ith dimension, the amount of padding inserted before and after the dimension is `explicit_paddings[2 * i]` and `explicit_paddings[2 * i + 1]`, respectively. If `padding` is not `\"EXPLICIT\"`, `explicit_paddings` must be empty.\n- data_format: Specify the data format of the input and output data. With the default format \"NHWC\", the data is stored in the order of: \\[batch, in_height, in_width, in_channels\\]. Alternatively, the format could be \"NCHW\", the data storage order of: \\[batch, in_channels, in_height, in_width\\].\n- dilations: 1-D tensor of length 4. The dilation factor for each dimension of `input`. If set to k \\\u003e 1, there will be k-1 skipped cells between each filter element on that dimension. The dimension order is determined by the value of `data_format`, see above for details. Dilations in the batch and depth dimensions must be 1.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.0/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): 4-D with shape `[batch, in_height, in_width, in_channels]`.
