移动边界截断随机逼近的收敛速度

Rate of Convergence of Truncated Stochastic Approximation Procedures with Moving Bounds

Teo Sharia, Lei Zhong

摘要:

本文研究了具有三个主要特征的随机逼近过程:随机移动界截断、矩阵值随机步长序列和动态变化的随机回归函数。我们研究收敛性和收敛速度。主要结果的补充推论建立各种各样的充分条件,主要重点是参数统计估计。通过实例和特殊情况说明了该理论。

英文摘要:

The paper is concerned with stochastic approximation procedures having three main characteristics: truncations with random moving bounds, a matrix valued random step-size sequence, and a dynamically changing random regression function. We study convergence and rate of convergence. Main results are supplemented with corollaries to establish various sets of sufficient conditions, with the main emphases on the parametric statistical estimation. The theory is illustrated by examples and special cases.
