tf.nn.conv2d_backprop_input
Computes the gradients of convolution with respect to the input.
tf.nn.conv2d_backprop_input( input_sizes, filter=None, out_backprop=None, strides=None, padding=None, use_cudnn_on_gpu=True, data_format='NHWC', dilations=[1, 1, 1, 1], name=None, filters=None )
Args | ||
---|---|---|
input_sizes | A Tensor of type int32 . An integer vector representing the shape of input , where input is a 4-D [batch, height, width, channels] tensor. | |
filter | A Tensor . Must be one of the following types: half , bfloat16 , float32 , float64 . 4-D with shape [filter_height, filter_width, in_channels, out_channels] . | |
out_backprop | A Tensor . Must have the same type as filter . 4-D with shape [batch, out_height, out_width, out_channels] . Gradients w.r.t. the output of the convolution. | |
strides | A list of ints . 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. | |
padding | Either the string "SAME"or "VALID"indicating the type of padding algorithm to use, or a list indicating the explicit paddings at the start and end of each dimension. When explicit padding is used and data_format is "NHWC", this should be in the form [[0, 0], [pad_top, pad_bottom], [pad_left, pad_right], [0, 0]]. When explicit padding used and data_format is "NCHW", this should be in the form [[0, 0], [0, 0], [pad_top, pad_bottom], [pad_left, pad_right]]. </td> </tr><tr> <td> use_cudnn_on_gpu</td> <td> An optional bool. Defaults to True. </td> </tr><tr> <td> data_format</td> <td> An optional stringfrom: "NHWC", "NCHW". Defaults to "NHWC". 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]. </td> </tr><tr> <td> dilations</td> <td> An optional list of ints. Defaults to [1, 1, 1, 1]. 1-D tensor of length 4. The dilation factor for each dimension of input. 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 must be 1. </td> </tr><tr> <td> name</td> <td> A name for the operation (optional). </td> </tr><tr> <td> filters` | Alias for filter. |
Returns | |

A Tensor . Has the same type as filter . |
