CycleGAN

Cycle Consistent GAN

• G
  • $x \rightarrow y$
• F
  • $y \rightarrow x$
• Aims to bridge gap across domains
  • Zebras-horses
  • Audi-BMW
• Learn bidirectional mapping function
• Transitivity regularises training
• $x \rightarrow y'$
  • $y' \rightarrow x''$
    • $x == x''$
    • Cycle consistency
• Requires two datasets
  • One for each domain
  • Not directly paired
    • Unlike edge map $\rightarrow$ bag
