https://arxiv.org/pdf/2010.02502(Oct 2022 ICLR 2021)https://github.com/ermongroup/ddimAbstractDenoising diffusion probabilistic models (DDPMs) have achieved high quality image generation without adversarial training, yet they require simulating a Markov chain for many steps in order to produce a sample. To accelerate sampling, we present denoising diffusion implicit models (DDIMs), a more effici..

https://arxiv.org/pdf/2302.08215(Jun 2023 ICML 2023) 짜잔~ 종합선물세트 입니다~!f-divergence로 대동단결.옛다. 크리스마스 선물 받아랏~! 너무 당연한 이야기이지만, 목표를 어떻게 설정하느냐에 따라 인생은 완전히 달라진다.목적지 변경은 우리를 완전히 다른 방향으로 이끌기도 한다.objective function (loss function)에 따라서 model의 behavior가 달라지는 건 참 흥미진진하다.(좀 더 구체적으로는..- 어떠한 measure로 target distribution을 approximate할 것인가- metric에 따라 convergence하는 양상은 어떻게 달라지는가) 이 논문을 읽는데 왜케 행복하지? ㅜㅜ 이 논문을 읽기 위해..

https://arxiv.org/pdf/2112.00791(Jun 2022 ICML 2022)AbstractMachine learning is shifting towards general-purpose pretrained generative models, trained in a self-supervised manner on large amounts of data, which can then be applied to solve a large number of tasks. However, due to their generic training methodology, these models often fail to meet some of the downstream requirements (e.g., halluc..
