Question 1: Short answer

mediumAI-checkedGenerative Adversarial Networks

A CycleGAN translates a real image xx to the other domain and back, giving x^\hat{x}. Its cycle-consistency loss is λ\lambda times the mean absolute pixel difference, with λ=10\lambda = 10. For a toy 4-pixel image x=(0.5,−0.2,0.1,0.0)x = (0.5, -0.2, 0.1, 0.0) and reconstruction x^=(0.4,−0.2,0.3,0.1)\hat{x} = (0.4, -0.2, 0.3, 0.1), what is the loss?

a number, e.g. 0.5
