WebJun 8, 2024 · Our invertible glow-like modules express intra-unit affine coupling as a fusion of a densely connected block and Nyström self-attention. We refer to our architecture as DenseFlow since both cross-unit and intra-unit couplings rely on dense connectivity. WebIn the afﬁne coupling layer, channels in the same half never directly modify one another. Without mixing information across channels, this would be a severe restriction. Following Glow [1], we mix information across channels by adding an invertible 1x1 convolution layer before each afﬁne coupling layer. The W weights of these convolutions ...
