For an overview of supported state-space model forms and to learn how to create a model in MATLAB®, seeCreate Continuous State-Space Models for Economic Data Analysis. After creating a standard or diffuse model, you can, for example, estimate any unknown parameters using time series data, ...
State Space Models(SSM)“状态空间模型”一词广泛涵盖涉及潜在状态的任何循环过程,并已用于描述跨多个学科的各种概念。 基于物理举个例子:由常规物理规律可以研究系统的三个维度:系统输入、系统输出和状态量,给定 u(t) 为系统输入即拉力, y(t) 为系统输出即位移量,该系统的状态可以有位移、速度、加速度等等更深...
State-space models with free, canonical, and structured parameterizations; equivalent ARMAX and output-error (OE) models State-space modelsare models that use state variables to describe a system by a set of first-order differential or difference equations, rather than by one or morenth-order di...
State-space models provide a scalable approach to modeling MIMO systems - those with multiple inputs and outputs. We define for state-space models many of the familiar concepts from transfer function modeling, such as poles and transfer functions. Further, it is shown how many of the techniques...
这篇文章[1]采用了 conditional diffusion model 来做时间序列的 imputation 以及 forecasting 任务。本文的亮点在于,diffusion model 的网络结构不再是 CSDI[2] 中的transformer 结构,而是 structured state-space model(SSM)。我们可以把这种结构理解为 RNN、一维 CNN 以及transformer 的平替结构,都是 seq-to-seq 模...
State-space Models Adrian Wills ∗ and Brett Ninness Abstract This chapter examines the estimation of multivariable linear models for which the parameters vary in a time-varying manner that depends in an affine fashion on a known or otherwise measured signal. These locally linear models which ...
State space models, also termed dynamic models, relate time series observations or longitudinal data { y t } to unobserved "states" 伪 t by an observation model for y t given 伪 t . The states, which may be, e.g., unobserved trend and seasonal components or time-varying covariate ...

状态空间模型（SSM）是广泛应用于各类循环过程的模型，尤其在涉及潜在状态领域有着广泛应用。物理中一个简单的例子，如弹簧-质量-阻尼系统（SMD），可以清晰展示SSM的核心。系统输入为拉力，系统输出为位移量。在该系统中，位移、速度、加速度等是系统的状态，能够反映更深层次的潜在特征。SSM通常通过两个...
