Network architecture of cycleGAN. $G_{\theta }:\mathcal{Y}\mapsto \mathcal{X},H_{\phi }:\mathcal{X}\mapsto \mathcal{Y}$ are the generators responsible for inter-domain mapping. D_X, D_Y are discriminators, constructing ${\mathcal{L}}_{GAN}$. GAN loss is simultaneously optimized together with ${\mathcal{L}}_{c\mathit{y}cle}$
