摘要:

神经网络的逼近能力是否有理论保证?这个问题的答案是“神经网络的通用逼近定理“。该定理指出,在适当的设置下,神经网络在一定的函数空间中是稠密的。本文对前向神经网络的普适逼近定理、逼近速度问题(中间单元数与逼近误差的关系)以及日本的Barron空间作了全面的解释。

英文摘要:

Is there any theoretical guarantee for the approximation ability of neural networks? The answer to this question is the "Universal Approximation Theorem for Neural Networks". This theorem states that a neural network is dense in a certain function space under an appropriate setting. This paper is a comprehensive explanation of the universal approximation theorem for feedforward neural networks, its approximation rate problem (the relation between the number of intermediate units and the approximation error), and Barron space in Japanese.
