论文摘要
深度神经网络(DNN)的理论分析可以说是机器学习中最具挑战性的研究方向之一(ML),因为科学家要求从科学家那里奠定新颖的统计学习基础,以在实践中解释其行为。尽管最近在这项工作中取得了一些成功,但使用来自ML社区以外的其他科学领域的工具可以分析DNN的问题尚未得到应有的关注。在本文中,我们探讨了DNNS与游戏理论(GT)之间的相互作用,并展示一个人在分析前者时如何从后者的经典可用结果中受益。特别是,我们考虑了广泛研究的拥堵游戏类,并说明了它们与线性和非线性DNN的内在相关性以及其损失表面的性质。除了从文献中检索最先进的结果外,我们认为我们的工作提供了一种非常有前途的新颖工具,可以通过提出具体的开放问题来分析DNN和支持这一主张,这些问题可以显着提高我们对DNN的理解。
The theoretical analysis of deep neural networks (DNN) is arguably among the most challenging research directions in machine learning (ML) right now, as it requires from scientists to lay novel statistical learning foundations to explain their behaviour in practice. While some success has been achieved recently in this endeavour, the question on whether DNNs can be analyzed using the tools from other scientific fields outside the ML community has not received the attention it may well have deserved. In this paper, we explore the interplay between DNNs and game theory (GT), and show how one can benefit from the classic readily available results from the latter when analyzing the former. In particular, we consider the widely studied class of congestion games, and illustrate their intrinsic relatedness to both linear and non-linear DNNs and to the properties of their loss surface. Beyond retrieving the state-of-the-art results from the literature, we argue that our work provides a very promising novel tool for analyzing the DNNs and support this claim by proposing concrete open problems that can advance significantly our understanding of DNNs when solved.
