Limitations of pix2pix, DTN, DiscoGAN & CycleGAN? They produce single answer. They are deterministic models. Translates an image in one-to-one Paired set, One-to-One : pix2pix (CVPR2017) Unpaired set, One-to-One : DTN (ICLR2017), CycleGAN (ICCV2017) Paired set, One-to-Many : ???

Unpaired Image-to-Image Translation using Cycle-Consistent Adversarial Networks (CycleGAN) from UC Berkeley (pix2pix upgrade) & Learning to Discover Cross-Domain Relations with Generative Adversarial Networks (DiscoGAN) from SK T-Brain DiscoGAN & CycleGAN Almost Identical concept. DiscoGAN came 15 days earlier. Low resolution ($64 \times 64$) CycleGAN has better qualitative results ($256 \times

2. Unsupervised Cross-Domain Image Generation (DTN) published to ICLR2017 by Yaniv Taigman, Adam Polyak, Lior Wolf Learn $ G: S \rightarrow T $ of two related domains, $ S $ and $ T $ without labels! (labels of images are usually expensive) Baseline model $ D $ : discriminator, $ G $ : generator, $ f $ : context encoder. outputs feature. (128-dim) \begin{equation}
