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...
You can create a standard, diffuse, or Bayesian linear or nonlinear state-space model usingssm,dssm,bssm, orbnlssm, respectively. 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 ...
第三部分,什么是State Space Model 还是先看看什么是State Space(状态空间) 状态空间包含完整描述系统的最小数量的变量。它是一种通过定义系统的可能状态来以数学方式表示问题的方法。 想象你在一个迷宫里,目标是从起点走到终点。在这个迷宫中,每个位置(比如你现在站的格子)都可以看作是一个“状态”。迷宫的每个格...

VMamba在有效降低注意力复杂度方面的关键概念继承自选择性扫描空间状态序列模型(Selective Scan Space State Sequential Model, S6 )。S6使一维数组(例如文本序列)中的每个元素通过压缩隐藏状态与先前扫描的任何样本进行交互,有效地将二次复杂度降为线性。
