Fassarar da ba a haɗa ta CycleGAN
CycleGAN yana koyon fassarar hotuna tsakanin wurare biyu na gani (kamar dawakai zuwa zebra, ko hotuna zuwa zane-zane) ba tare da buƙatar daidaitawa kafin-da-bayan misali nau'i-nau'i ba.

It matters because collecting paired training data is often impossible, and CycleGAN unlocks style transfer for messy real-world datasets.
