为了更好地让 SSM 捕捉长序列时序关系,文章[4]中使用了固定初始化的矩阵 A,称为 HiPPO Theory,并且提出了基于 SSM 的 Structured State Space sequence model (S4) 模型。本文中的 diffusion model 采取的就是 S4 模型。 本文中最重要的贡献在于提出了Structured State Space Diffusion(SSSD) 架构,在这里简化为...
To address the above issues, this study proposes a spatio-temporal degradation model named spatio-temporal graph structured state space sequence model (ST-GS4D) to effectively extract degradation features for RUL prediction. The ST-GS4D is an innovative prediction framework that integrates structured...

The continuous-time state-space model structure is defined by the following equation: ˙x(t)=Fx(t)+Gu(t)+∼Kw(t)y(t)=Hx(t)+Du(t)+w(t)x(0)=x0 Construct the parameter matrices and initialize the parameter values using the nominal parameter values. ...
This position paper argues for the use of structured generative models (SGMs) for the understanding of static scenes. This requires the reconstruction of a 3D scene from an input image (or a set of multi-view images), whereby the contents of the image(s) are causally explained in terms of...
We formulate and develop the Structured Prediction Cascade architecture: a sequence of increasingly complex models that progressively filter the space of possible outputs. The key principle of our approach is that each model in the cascade is optimized to accurately filter and refine the structured ...
We also show experimentally that each aspect of our expressive CRM model space makes a positive contribution to the learned models on yeast and fly data./p pConclusion/p pStructural aspects are an important part of CRMs, both in terms of interpreting them biologically and learning them ...
The axial resolution of three-dimensional structured illumination microscopy (3D SIM) is limited to ∼300 nm. Here we present two distinct, complementary methods to improve axial resolution in 3D SIM with minimal or no modification to the optical sy
