摘要:

在量子力学中,范数平方波函数可以被解释为描述粒子在给定位置或动量下被测量的可能性的概率密度。这种统计特性是微观世界的核心。与此同时,材料的机器学习反求设计引起了人们的广泛关注,并产生了各种物质工程智能系统。在这里,受量子理论的启发,我们提出了一种概率深度学习范式,用于功能元结构的逆向设计。我们的概率密度为基础的神经网络(PDN)可以准确地捕捉所有合理的元结构,以满足所需的性能。概率密度分布中的局部最大值对应于最可能的候选者。我们通过为每个目标透射谱设计多个元结构来验证这种方法,以丰富设计选择。

英文摘要:

In quantum mechanics, a norm squared wave function can be interpreted as the probability density that describes the likelihood of a particle to be measured in a given position or momentum. This statistical property is at the core of the microcosmos. Meanwhile, machine learning inverse design of materials raised intensive attention, resulting in various intelligent systems for matter engineering. Here, inspired by quantum theory, we propose a probabilistic deep learning paradigm for the inverse design of functional meta-structures. Our probability-density-based neural network (PDN) can accurately capture all plausible meta-structures to meet the desired performances. Local maxima in probability density distribution correspond to the most likely candidates. We verify this approach by designing multiple meta-structures for each targeted transmission spectrum to enrich design choices.
