The transpose of conv2d
.
tf.nn.conv2d_transpose(
value=None, filter=None, output_shape=None, strides=None, padding='SAME',
data_format='NHWC', name=None, input=None, filters=None, dilations=None
)
This operation is sometimes called "deconvolution" after Deconvolutional
Networks,
but is really the transpose (gradient) of conv2d
rather than an actual
deconvolution.
Args |
value
|
A 4-D Tensor of type float and shape
[batch, height, width, in_channels] for NHWC data format or
[batch, in_channels, height, width] for NCHW data format.
|
filter
|
A 4-D Tensor with the same type as value and shape
[height, width, output_channels, in_channels] . filter 's
in_channels dimension must match that of value .
|
output_shape
|
A 1-D Tensor representing the output shape of the
deconvolution op.
|
strides
|
An int or list of ints that has length 1 , 2 or 4 . The
stride of the sliding window for each dimension of input . If a single
value is given it is replicated in the H and W dimension. By default
the N and C dimensions are set to 0. The dimension order is determined
by the value of data_format , see below for details.
|
padding
|
A string, either 'VALID' or 'SAME' . The padding algorithm.
See the "returns" section of tf.nn.convolution for details.
|
data_format
|
A string. 'NHWC' and 'NCHW' are supported.
|
name
|
Optional name for the returned tensor.
|
input
|
Alias for value.
|
filters
|
Alias for filter.
|
dilations
|
An int or list of ints that has length 1 , 2 or 4 ,
defaults to 1. The dilation factor for each dimension ofinput . If a
single value is given it is replicated in the H and W dimension. By
default the N and C dimensions are set to 1. If set to k > 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 if a 4-d tensor
must be 1.
|
Returns |
A Tensor with the same type as value .
|
Raises |
ValueError
|
If input/output depth does not match filter 's shape, or if
padding is other than 'VALID' or 'SAME' .
