1991年的一篇经典文章“Approximation Capabilities of Multilayer Feedforward Networks”对此做了详细的介绍和讨论,本文对该文章做一个解读。 概述 如果我们将网络结构认为是从 Rk→Rl 的一个映射,则神经网络的逼近性质就是在研究任意的映射能够被该网络逼近的有多好。在这里,不同的任务需要采用不同的度量来刻画逼近...

“Multilayer feedforward networks areuniversal approximators”Kur Hornik, Maxwell Stinchcombe and Halber White(1989)Presenter: Sonia Todorova
This paper rigorously establishes that standard multilayer feedforward networks with as few as one hidden layer using arbitrary squashing functions are capable of approximating any Borel measurable function from one finite dimensional space to another to any desired degree of accuracy, provided sufficiently...
