SSM(State Space Model,状态空间模型)是一种用于描述时间序列数据的统计模型。它广泛应用于机器学习和统计学中,用于处理动态系统和时变过程。SSM可以捕捉系统状态随着时间的变化,以及观察到的数据与这些状态之间的关系。 SSM的基本构成 状态空间表示 状态空间模型由两个主要部分组成: 状态方程(State Equation):描述系统...
Example on Time-Varying CAPM Model 一点小小的数学练习,如何用State space model来改写一些常见的ARMA模型 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+b1y...
In addition to the state equations, a state space model also includes an output equation, which describes how the state vector is related to the output of the system. This allows the model to be used to predict the output of the system for a given set of inputs. Overall, state space ...
Put the following equations into state space form by determining matrices A, B, C, and D. ˙x=Ax+Bux˙=Ax+Bu y=Cx+Duy=Cx+Du Simulate a step response for each model and determine whether the system is stable or unstable. 1. First order differential equation ...
A continuous state-space Markov process, orstate-space model, allows for trajectories through a continuous state space. The underlying Markov process is typically unobserved. A supplemental observation equation describes the evolution of measurable characteristics of the system, dependent on the Markov pro...
The state–space model concerned is defined as: (1a)sit+1=fisit,θit,t+wit+1 (1b)yit=hisit,θit,t+vit In Eqn. (1a)si(t) denotes the state of systemiat timet, a vector-valued (hence bold-faced) latent (i.e., not directly observed) process. The difference equation (1a) expr...

These two equations are the core of the State Space Model. The two equations will be referenced throughout this guide. To make them a bit more intuitive, they are color-coded so you can quickly reference them. The state equation describes how the state changes (through matrix A) based on...
Structure of Neural State-Space Models A state-space model is a representation of a dynamic system that uses a state equation and an output equation. The state equation is a set of first-order ordinary differential equations (ODEs) or difference equations, which are often derived from first pri...
