#include <nn_ops.h> Menghitung gradien konvolusi sehubungan dengan input.
Ringkasan
Argumen:
- ruang lingkup: Objek Lingkup
- input_sizes: Vektor bilangan bulat yang mewakili bentuk
input , dengan input adalah tensor [batch, height, width, channels] 4-D. - filter: 4-D dengan bentuk
[filter_height, filter_width, in_channels, out_channels] . - out_backprop: 4-D dengan bentuk
[batch, out_height, out_width, out_channels] . Gradien menentukan keluaran konvolusi. - langkah: Langkah jendela geser untuk setiap dimensi masukan konvolusi. Harus berada dalam urutan yang sama dengan dimensi yang ditentukan dengan format.
- padding: Jenis algoritma padding yang akan digunakan.
Atribut opsional (lihat Attrs ):
- eksplisit_paddings: Jika
padding adalah "EXPLICIT" , daftar jumlah padding eksplisit. Untuk dimensi ke-i, jumlah padding yang disisipkan sebelum dan sesudah dimensi masing-masing adalah explicit_paddings[2 * i] dan explicit_paddings[2 * i + 1] . Jika padding bukan "EXPLICIT" , explicit_paddings harus kosong. - data_format: Menentukan format data input dan output data. Dengan format default "NHWC", data disimpan dalam urutan: [batch, in_height, in_width, in_channels]. Alternatifnya, formatnya bisa berupa "NCHW", urutan penyimpanan data: [batch, in_channels, in_height, in_width].
- dilatasi: tensor 1-D dengan panjang 4. Faktor dilatasi untuk setiap dimensi
input . Jika diatur ke k > 1, akan ada k-1 sel yang dilewati di antara setiap elemen filter pada dimensi tersebut. Urutan dimensi ditentukan oleh nilai data_format , lihat di atas untuk detailnya. Pelebaran dalam dimensi batch dan kedalaman harus 1.
Pengembalian:
-
Output : 4-D dengan bentuk [batch, in_height, in_width, in_channels] . Gradien menulis masukan konvolusi.

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/r1.15/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/r1.15/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): 4-D with shape `[batch, in_height, in_width, in_channels]`. Gradient w.r.t. the input of the convolution.\n\n\u003cbr /\u003e\n\n| ### Constructors and Destructors ||\n|---|---|\n|
