摘要:

材料性能的预测对材料的设计和筛选具有重要意义,是一个关键问题。提出了一种全新的、通用的机器学习方法用于材料性能预测。作为一个有代表性的例子,聚合物的相容性被选择来证明我们的方法的有效性。具体而言,我们从相关文献中挖掘数据,建立一个特定的数据库,并给出一个预测的基础上的基本分子结构的共混聚合物,并作为辅助,共混组成。我们的模型在由数千个条目组成的数据集上获得了至少75%的准确率。我们证明了结构和性能之间的关系可以通过机器学习方法来学习和模拟。

英文摘要:

Prediction of material property is a key problem because of its significance to material design and screening. We present a brand-new and general machine learning method for material property prediction. As a representative example, polymer compatibility is chosen to demonstrate the effectiveness of our method. Specifically, we mine data from related literature to build a specific database and give a prediction based on the basic molecular structures of blending polymers and, as auxiliary, the blending composition. Our model obtains at least 75% accuracy on the dataset consisting of thousands of entries. We demonstrate that the relationship between structure and properties can be learned and simulated by machine learning method.
