SGM 在扩散模型大家庭中算是一个重要的思想,也涉及很多复杂的东西,如有写得不准确的地方还请指出。 本人数学不好,尽量避免复杂公式和各种证明 (´。_。`) 标准布朗运动 SGM(Score-based Generative Model) 说来话长,至于有多长,一直可以追溯到布朗运动(啊对,就是初高中物理课上学的那个……) 现在,假设我们...
Score-based generative models (SGMs) have recently emerged as a promising class of generative models. However, a fundamental limitation is that their inference is very slow due to a need for many (e.g., 2000) iterations of sequential computations. An intuitive acceleration method is to reduce ...
Score-based generative modeling through stochastic differential equations[J]. arXiv preprint arXiv:2011.13456, 2020 (ICLR2021). openreview.net/pdf? score-based generateive model(SGM)在一开始的时候就有引入condition的概念了,这里根据贝叶斯公式把这件事情定义成逆向问题,即inverse problem。 首先回顾一下SGM...

Here, we propose the Latent Score-based Generative Model (LSGM), a novel approach that trains SGMs in a latent space, relying on the variational autoencoder framework. Moving from data to latent space allows us to train more expressive generative models, apply SGMs to non-continuous data, and...
Antibody-SGM, a Score-Based Generative Model for Antibody Heavy-Chain Design 来自 国家科技图书文献中心 喜欢 0 阅读量: 3 作者:X Xie,PA Valiente,JS Lee,J Kim,PM Kim 摘要: Traditional computational methods for antibody design involved random mutagenesis followed by energy function assessment for ...
LSGM trains a score-based generative model (a.k.a. a denoising diffusion model) in the latent space of a variational autoencoder. It currently achieves state-of-the-art generative performance on several image datasets.RequirementsLSGM is built in Python 3.8 using PyTorch 1.8.0. Please use the...
Medical image reconstruction with pre-trained score-based generative models (SGMs) has advantages over other existing state-of-the-art deep-learned reconstruction methods, including improved resilience to different scanner setups and advanced image distribution modeling. SGM-based reconstruction has recently...
With the great success of generative models such as StyleGAN [16] and the diffusion model [17] in recent years, text-guided image editing has become a hot topic. While text-guided image editing based on the diffusion model achieves particularly high performance, the user must expend effort ...
