Detailed Description

The DeconvolutionLayer convolves the input with a bank of learned filtered, and (optionally) add biases, treating filters and convolution parameters in the opposite sense as ConvolutionLayer. This layer is initialized with the MyCaffe.param.ConvolutionParameter.

ConvolutionLayer computes each output value by dotting an input window with a filter; DeconvolutionLayer multiplies each input value by a filter elementwise, and sums over the resulting output windows. In other words, DeconvolutionLayer is ConvolutionLayer with the forward and backward passes reversed. DeconvolutionLayer reuses ConvolutionParameter for its parameters, but they take the opposite sense in ConvolutionLayer (so padding is removed from the output rather than added to the input, and stride results in upsampling rander than downsampling).

	)

The DeconvolutionLayer constructor.

Parameters

cuda	Specifies the CudaDnn connection to Cuda.
log	Specifies the Log for output.
p	Provides ConvolutionParameter convolution_param with DeconvolutionLayer options: num_output. The number of filters. kernel_size / kernel_h / kernel_w. The filter dimensions, given by kernel_size for square filters or kernel_h and kernel-w for rectangular filters. stride / stride_h / stride_w. (optional, default 1). The filter stride, given by stride_size for equal dimensions of stride_h and stride_w for different strides. By default the convolution is dense with stride 1. pad / pad_h / pad_w. (optional, default 0). The zero-padding for convolutions, given by pad for equal dimensions or pad_h and pad_w for different padding. Input padding is computed implicitly instead of actual padding. dilation (optional, default 1). The filter dilation, given by dilation_size for equal dimensions for different dilation. By default the convolution has dilation 1. group (optional, default 1). The number of filter groups. Group convolution is a method for reducing parameterization by selectively connecting input and output channels. The input and output channel dimensions must be divisible by the number of groups. For group = 1, the convolutionjf ilters input and output channels are separeated s.t. each group takes 1/group of the input channels and makes 1/group of the output channels. Concretely 4 input channels, 8 output channels, and 2 groups separate input chanels 1-2 and output channels 1-4 into the first group and input channels 3-4 and output channels 5-8 into the xecond group. bias_term (optional, default, true). Whether to have a bias. engine: convolution has Engine.CAFFE (matrix multiplication) and Engine.CUDNN (library kernels + stream parallelism) engines.
