“Classifier-Free Diffusion Guidance”는 조건부 생성(conditional generation) Diffusion Model을 개선한 논문입니다. 이 논문이 발표되기 이전, 특정 클래스의 이미지를 생성하도록 모델을 유도하는 일반적인 방법은 별도의 이미지 분류기(Classifier)를 활용하는 ‘Classifier Guidance’였습니다. 이 방식은 효과적이었으나, Diffusion Model 외에 노이즈 낀 이...
2020년 발표된 “Denoising Diffusion Probabilistic Models” (DDPM)은 생성 모델 연구에 중요한 전환점을 제시한 논문입니다. 당시 Generative Adversarial Networks (GANs)는 훈련 불안정성과 모드 붕괴(mode collapse)와 같은 문제점에도 불구하고 높은 성능으로 인해 고품질 이미지 생성 분야에서 널리 사용되고 있었습니다. DDPM은 이러한 상황 속에서 Diffusion...
