Menghitung gradien konvolusi mendalam sehubungan dengan masukan.
Ringkasan
Argumen:
- ruang lingkup: Objek Lingkup
- input_sizes: Vektor bilangan bulat yang mewakili bentuk
input
, berdasarkan data_format
. Misalnya, jika data_format
adalah 'NHWC' maka input
adalah tensor [batch, height, width, channels]
4-D. - filter: 4-D dengan bentuk
[filter_height, filter_width, in_channels, depthwise_multiplier]
. - out_backprop: 4-D dengan bentuk berdasarkan
data_format
. Misalnya, jika data_format
adalah 'NHWC' maka bentuk out_backprop adalah [batch, out_height, out_width, out_channels]
. Gradien menentukan keluaran konvolusi. - langkah: Langkah jendela geser untuk setiap dimensi masukan konvolusi.
- padding: Jenis algoritma padding yang akan digunakan.
Atribut opsional (lihat Attrs
):
- data_format: Menentukan format data input dan output data. Dengan format default "NHWC", data disimpan dalam urutan: [batch, tinggi, lebar, saluran]. Alternatifnya, formatnya bisa berupa "NCHW", urutan penyimpanan data: [batch, saluran, tinggi, lebar].
- 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 sesuai data_format
. Misalnya, jika data_format
adalah 'NHWC', bentuk keluarannya adalah [batch, in_height, in_width, in_channels]
. Gradien menulis masukan konvolusi.

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`. For example, if `data_format` is 'NHWC', output shape is `[batch, in_height, in_width, in_channels]`.
