本文来自于 NIPS 2021[1],是 diffusion model 在时间序列领域基石性的文章。虽然本文重点关注的是时间序列的 imputation 任务,但是该方法也可以用于interpolation和forecasting任务。本文使用了conditional score-based diffusion model,以可以观测到的值为条件,来得到空缺值的条件分布,模型示意图如下所示: 使用CSDI 做时间...
To overcome these obstacles, we propose a conditional score-based diffusion model specifically designed to generate CTh trajectories with the given baseline information, such as age, sex, and initial diagnosis. Our conditional diffusion model utilizes all available data during the training phase to ...

In this paper, we propose Conditional Score-based Diffusion models for Imputation (CSDI), a novel time series imputation method that utilizes score-based diffusion models conditioned on observed data. Unlike existing score-based approaches, the conditional diffusion model is explicitly trained for ...

Score-based Diffusion Models We will follow the usual construction of continuous dif- fusion process x(t), t ∈ [0, T ] with x(t) ∈ Rd [34]. Con- 12414 cretely, we want x(0) ∼ p0(x), where p0 = pdata, and x(T...
Score-based Diffusion Models Score-based Diffusion Models (SBDMs) [43, 45] are a kind of diffusion model based on score theory, which re- veals that the essence of diffusion models is to estimate the score function ∇xt log p(xt), where xt is noisy data. Dur-...
