SSM指的是结构化状态空间序列模型(Structured state space sequence models,S4)是最近一类用于深度学习的序列模型,与 RNN、CNN 和经典状态空间模型有广泛联系。它们受到一个特殊连续系统的启发,该系统通过隐含的潜在状态h(t)∈RN,映射一个一维函数或序列x(t)∈R↦y(t)∈R。 S4模型可由四个参数(Δ,A,B,C)...
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 SSSDS4 。并提出了针对于两种已有方法的 S4 改进版,分别是 non-autoregressive SaShiMi[5] 架构SSSDSA 以及使用 S4 改进后的 CSDI 架构[6] CSDIS4。 SSSDS4 架构如下...
fMRI-S4 capture short- and long- range temporal dependencies in the signal using 1D convolutions and the recently introduced state-space models S4. The proposed architecture is lightweight, sample-efficient and robust across tasks/datasets. We validate fMRI-S4 on the tasks of diagnosing major ...

State Space Models (SSMs) have emerged as promising alternatives for sequence modeling paradigms, especially with the advent of S4 and its variants, such as S4nd, Hippo, Hyena, Diagonal State Spaces (DSS), Gated State Spaces (GSS), Linear Recurrent Unit (LRU), Liquid-S4, Long-Conv, Mega,...
In the LH recordings, as described above, two-class and three-class (one-versus-rest multiclass classification72) models were computed using a nonlinear radial basis or linear kernel (depending on the dimensionality of the feature space). Linear SVMs were used to classify the population activity...

A new mixing state module is established based on this finding and successfully applied in global and regional models, which increases the accuracy of aerosol climate effect estimations. Our theoretical framework links observations with model simulations in both mixing state description and light ...
For a model with a finite state space, test cases would be generated directly from this machine, without needing further adjustment. However, since the test space of this sample model is infinite, it must be sliced in the Cord script before generating tests. The static model template provides...
