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: ...
We have applied the state-space model to the Korean stock market under restrictions imposed by the present-value relation. Our main findings are (i) expected stock returns vary over time and have persistent and predictable component, (ii) expected dividend growth rates do not contain persistent ...
今天和大家分享的主题是“状态空间模型(State Space Model)”。说到状态空间模型,笔者最早接触到这一名字是在读Koop和Korobilis(2014)关于使用TVP-FAVAR模型构建金融状况指数(Financial Conditions Index,FCI)论文的时候,文中用了“State Function”和“Measurement Function”的叫法。后来发现之前学过的常AR模型、MA模型...
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。
Consider the state space model defined by equations (1)–(3). We have p.x 0:t |z 1:t / = p.x 0:t |y 1:t / p.y 1:t |z 1:t / dy 1:t : Thus if we obtain (through an SMC method described further) an approximation of the prob- ability distribution that is associate...
