For the calculation of large/medium clusters, first-principles calculations have heavy computational burden, while the traditional force-field methods are not accurate enough. In recent years, the rising tide of machine learning began to penetrate into various academic disciplines including chemistry. The method based on machine learning may provide a new way between first-principles approach and traditional force-field model. The development of cluster potential energy model based on machine learning is expected to provide a new tool for the theoretical and computational research of clusters. 查看全文查看/发表评论下载PDF阅读器 相关附件：图1图2TOC封面版权转让声明书 -->
