tf.keras.ops.conv_transpose

General N-D convolution transpose.

tf.keras.ops.conv_transpose( inputs, kernel, strides, padding='valid', output_padding=None, data_format=None, dilation_rate=1 )

Also known as de-convolution. This ops supports 1D, 2D and 3D convolution.

inputs Tensor of rank N+2. inputs has shape (batch_size,) + inputs_spatial_shape + (num_channels,) if data_format="channels_last", or (batch_size, num_channels) + inputs_spatial_shape if data_format="channels_first".
kernel Tensor of rank N+2. kernel has shape [kernel_spatial_shape, num_output_channels, num_input_channels], num_input_channels should match the number of channels in inputs.
strides int or int tuple/list of len(inputs_spatial_shape), specifying the strides of the convolution along each spatial dimension. If strides is int, then every spatial dimension shares the same strides.
padding string, either "valid" or "same". "valid" means no padding is applied, and "same" results in padding evenly to the left/right or up/down of the input such that output has the same height/width dimension as the input when strides=1.
output_padding int or int tuple/list of len(inputs_spatial_shape), specifying the amount of padding along the height and width of the output tensor. Can be a single integer to specify the same value for all spatial dimensions. The amount of output padding along a given dimension must be lower than the stride along that same dimension. If set to None (default), the output shape is inferred.
data_format A string, either "channels_last" or "channels_first". data_format determines the ordering of the dimensions in the inputs. If data_format="channels_last", inputs is of shape (batch_size, ..., channels) while if data_format="channels_first", inputs is of shape (batch_size, channels, ...).
dilation_rate int or int tuple/list of len(inputs_spatial_shape), specifying the dilation rate to use for dilated convolution. If dilation_rate is int, then every spatial dimension shares the same dilation_rate.

A tensor of rank N+2, the result of the conv operation.
