From f5f34bb068565bf9435ba5561aae1c9280db8bbe Mon Sep 17 00:00:00 2001 From: Pablo Tello Date: Tue, 22 Aug 2017 13:34:13 +0100 Subject: COMPMID-470: Neon Deconvolution. Implemented by up-sampling the input with zeros insertions between the input samples and convolving the Deconvolution kernels on the up-sampled result. The upsampling is performed by the function NEDeconvolutionLayerUpsample. Convolving is done by NEDirectConvolutionLayer.
