基于机器学习的分子原子化能快速精确建模

Fast and Accurate Modeling of Molecular Atomization Energies with Machine Learning

Matthias Rupp, Alexandre Tkatchenko, Klaus-Robert Müller, O. Anatole von Lilienfeld

摘要:

我们引入了一个机器学习模型来预测一组不同的有机分子的原子化能量,仅基于核电荷和原子位置。求解分子薛定谔方程的问题被映射到一个非线性统计回归问题的复杂性降低。回归模型进行训练,并与混合密度泛函理论计算的原子化能量进行比较。对七千多个有机小分子进行交叉验证,得出的平均绝对误差约为10 kcal/mol。证明了该方法对分子原子化势能曲线预测的适用性。

英文摘要:

We introduce a machine learning model to predict atomization energies of a diverse set of organic molecules, based on nuclear charges and atomic positions only. The problem of solving the molecular Schrödinger equation is mapped onto a non-linear statistical regression problem of reduced complexity. Regression models are trained on and compared to atomization energies computed with hybrid density-functional theory. Cross-validation over more than seven thousand small organic molecules yields a mean absolute error of ~10 kcal/mol. Applicability is demonstrated for the prediction of molecular atomization potential energy curves.
