You can create a standard, diffuse, or Bayesian linear or nonlinear state-space model using ssm, dssm, bssm, or bnlssm, respectively. For an overview of supported state-space model forms and to learn how to create a model in MATLAB®, see Create Continuous State-Space Models for Econom...
让我们逐步了解一般技术,以了解这些矩阵如何影响学习过程。 假设我们有一些输入信号x(t),该信号首先乘以矩阵 B,该矩阵描述了输入如何影响系统。 更新后的状态(类似于神经网络的隐藏状态)是一个包含环境核心“知识”的潜在空间。我们将状态与矩阵 A相乘,矩阵 A描述了所有内部状态如何连接,因为它们代表了系统的底层动态。

Here we do a little more practices on how to build the State Space models for ARMA time series models. 1. Give one way to represent the AR(2) model in the state space form. yt=a+b1yt−1+b2yt−2+ηtηt∼iid:N(0,σ2)αt=Tαt−1+c+Rηtαt=[ytyt−1],T=[b1b21...
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...
为了解决上面的问题,作者提出了一种新的选择性 SSM(Selective State Space Models,简称 S6 或 Mamba)。这种模型通过让 SSM 的矩阵 A、B、C 依赖于输入数据,从而实现了选择性。这意味着模型可以根据当前的输入动态地调整其状态,选择性地传播或忽略信息。 Mamba 集成了 S4 和 Transformer 的精华,一个更加高效(S4...
State-space representations of LTI modelsThe representation of a model in state-space is not unique. Coordinate transformation yields state-space models with different matrices but identical dynamics. State coordinate transformation can be useful for achieving minimal realizations of state-space models, or...

Stata’s newsspacecommand makes it easy to fit a wide variety of multivariate time-series models by casting them as linear state-space models, including vector autoregressive moving-average (VARMA) models, structural time-series (STS) models, and dynamic-factor models. ...
Linear Time Invariant (LTI) state space models are a linear representation of a dynamic system in either discrete or continuous time. Putting a model into state space form is the basis for many methods in process dynamics and control analysis. Below is the continuous time form of a model in...
