摘要
在材料科学领域,仅通过基于物理的模型来精确计算粘度、熔点和玻璃化转变温度等属性具有挑战性。数据驱动的机器学习(ML)也给构建 ML 模型带来了挑战,尤其是在数据有限的材料科学领域。为了解决这个问题,我们整合了分子动力学(MD)模拟中的物理信息描述符,以提高 ML 模型的准确性和可解释性。我们目前的研究重点是利用 MD 描述子准确预测液体系统的粘度。在这项工作中,我们从科学文献、出版物和在线数据库中整理出一个包含 4000 多种小型有机分子粘度的综合数据集。通过该数据集,我们开发出了基于描述符和图神经网络的定量结构-性质关系(QSPR)模型,用于预测各种粘度下与温度相关的粘度。QSPR 模型显示,包含 MD 描述因子可提高对实验粘度的预测,特别是在少于一千个数据点的小数据集规模下。此外,特征重要性工具显示,MD 描述子捕捉到的分子间相互作用对粘度预测最为重要。最后,QSPR 模型可以准确捕捉六种电池相关溶剂的粘度与温度之间的反比关系,其中一些溶剂未包含在原始数据集中。我们的研究突显了将 MD 描述因子纳入 QSPR 模型的有效性,这将提高单独使用基于物理的模型或在可用数据有限的情况下难以预测的特性的准确性。
Advancing material property prediction: using physics-informed machine learning models for viscosity
In materials science, accurately computing properties like viscosity, melting point, and glass transition temperatures solely through physics-based models is challenging. Data-driven machine learning (ML) also poses challenges in constructing ML models, especially in the material science domain where data is limited. To address this, we integrate physics-informed descriptors from molecular dynamics (MD) simulations to enhance the accuracy and interpretability of ML models. Our current study focuses on accurately predicting viscosity in liquid systems using MD descriptors. In this work, we curated a comprehensive dataset of over 4000 small organic molecules’ viscosities from scientific literature, publications, and online databases. This dataset enabled us to develop quantitative structure–property relationships (QSPR) consisting of descriptor-based and graph neural network models to predict temperature-dependent viscosities for a wide range of viscosities. The QSPR models reveal that including MD descriptors improves the prediction of experimental viscosities, particularly at the small data set scale of fewer than a thousand data points. Furthermore, feature importance tools reveal that intermolecular interactions captured by MD descriptors are most important for viscosity predictions. Finally, the QSPR models can accurately capture the inverse relationship between viscosity and temperature for six battery-relevant solvents, some of which were not included in the original data set. Our research highlights the effectiveness of incorporating MD descriptors into QSPR models, which leads to improved accuracy for properties that are difficult to predict when using physics-based models alone or when limited data is available.
