Calcola i gradienti della convoluzione in profondità rispetto all'input.
Riepilogo
Argomenti:
- scope: un oggetto Scope
- input_sizes: un vettore intero che rappresenta la forma di
input
, in base a data_format
. Ad esempio, se data_format
è "NHWC", input
è un tensore 4-D [batch, height, width, channels]
. - filter: 4-D con forma
[filter_height, filter_width, in_channels, depthwise_multiplier]
. - out_backprop: 4-D con forma basata su
data_format
. Ad esempio, se data_format
è 'NHWC', la forma out_backprop è [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.
- 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 memorizzati nell'ordine di: [lotto, altezza, larghezza, canali]. In alternativa, il formato potrebbe essere "NCHW", l'ordine di archiviazione dei dati di: [batch, canali, altezza, larghezza].
- 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 secondo data_format
. Ad esempio, se data_format
è 'NHWC', la forma di output è [batch, in_height, in_width, in_channels]
. Gradiente rispetto all'input della convoluzione.

For example, if `data_format` is 'NHWC' then `input` is a 4-D `[batch, height, width, channels]` tensor.\n- filter: 4-D with shape `[filter_height, filter_width, in_channels, depthwise_multiplier]`.\n- out_backprop: 4-D with shape based on `data_format`. For example, if `data_format` is 'NHWC' then out_backprop shape is `[batch, out_height, out_width, out_channels]`. 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.\n- padding: The type of padding algorithm to use.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r2.3/api_docs/cc/struct/tensorflow/ops/depthwise-conv2d-native-backprop-input/attrs#structtensorflow_1_1ops_1_1_depthwise_conv2d_native_backprop_input_1_1_attrs)):\n\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, height, width, channels\\]. Alternatively, the format could be \"NCHW\", the data storage order of: \\[batch, channels, height, 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/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): 4-D with shape according to `data_format`.
