Unsupervised  one-to-many image translation
We perform completely unsupervised one-sided image to image translation between a source domain and a target domain such that we preserve relevant underlying shared semantics.In particular, we are interested in a more difficult case than those typically addressed in the literature, where the source and target are far" enough that reconstruction-style or pixel-wise approaches fail.We argue that transferring said relevant information should involve both discarding source domain-specific information while incorporate target domain-specific information, the latter of which we model with a noisy prior distribution.In order to avoid the degenerate case where the generated samples are only explained by the prior distribution, we propose to minimize an estimate of the mutual information between the generated sample and the sample from the prior distribution.We discover that the architectural choices are an important factor to consider in order to preserve the shared semantic between and.We show state of the art results on the MNIST to SVHN task for unsupervised image to image translation.
We train an image to image translation network that take as input the source image and a sample from a prior distribution to generate a sample from the target distributionThis paper formalizes the problem of unsupervised translation and proposes an augmented GAN framework which uses the mutual information to avoid the degenerate caseThis paper formulates the problem of unsupervised one-to-many image translation and addresses the problem by minimizing the mutual information.
