π’ Check out 'Simpler Diffusion' led by @emiel_hoogeboom! Sigmoid loss is great for pixel diffusion in several ways, plus new architecture improvements and more :).
Is pixel diffusion passΓ©? In 'Simpler Diffusion' ( https://t.co/jE0W5qNJaG) , we achieve 1.5 FID on ImageNet512, and SOTA on 128x128 and 256x256. We ablated out a lot of complexity, making it truly 'simpler'. w/ @tejmensink @JonathanHeek @KayLamerigts @RuiqiGao @TimSalimans
