摘要:

准确高效地预测聚合物性质对聚合物设计至关重要。传统实验工具和基于密度泛函理论(DFT)的聚合物性质评估模拟既昂贵又耗时。近年来,大量基于图的分子模型涌现,并在分子数据分析中展现出巨大潜力。尽管取得了显著进展,这些模型往往忽略数据内的高阶和多尺度信息。本文提出用于聚合物性质分析的分子拓扑深度学习(Mol-TDL)。该方法将高阶相互作用与多尺度特性融入拓扑深度学习架构,核心思路是将聚合物分子表示为一系列不同尺度的单纯复形,并据此构建单纯神经网络。来自不同尺度的聚合信息可实现更准确的聚合物分子性质预测。

英文摘要:

Accurate and efficient prediction of polymer properties is of key importance for polymer design. Traditional experimental tools and density function theory (DFT)-based simulations for polymer property evaluation, are both expensive and time-consuming. Recently, a gigantic amount of graph-based molecular models have emerged and demonstrated huge potential in molecular data analysis. Even with the great progresses, these models tend to ignore the high-order and mutliscale information within the data. In this paper, we develop molecular topological deep learning (Mol-TDL) for polymer property analysis. Our Mol-TDL incorporates both high-order interactions and multiscale properties into topological deep learning architecture. The key idea is to represent polymer molecules as a series of simplicial complices at different scales and build up simplical neural networks accordingly. The aggregated information from different scales provides a more accurate prediction of polymer molecular properties.
