This technical note describes the recent updates of Graphormer, including architecture design modifications, and the adaption to 3D molecular dynamics simulation. The "Graphormer-V2" could attain better results on large-scale molecular modeling datasets than the vanilla one, and the performance gain could be consistently obtained on downstream tasks. In addition, we show that with a global receptive field and an adaptive aggregation strategy, Graphormer is more powerful than classic message-passing-based GNNs. Graphormer-V2 achieves much less MAE than the vanilla Graphormer on the PCQM4M quantum chemistry dataset used in KDD Cup 2021, where the latter one won the first place in this competition. In the meanwhile, Graphormer-V2 greatly outperforms the competitors in the recent Open Catalyst Challenge, which is a competition track on NeurIPS 2021 workshop, and aims to model the catalyst-adsorbate reaction system with advanced AI models.

翻译:本技术说明描述了石墨的最新更新,包括建筑设计修改和对3D分子动态模拟的调整。“Graphormer-V2”在大型分子模型数据集方面比香草类数据集取得比香草类数据集更好的效果,在下游任务方面可以持续地取得性能收益。此外,我们表明,有了全球可接受场和适应性聚合战略,石墨比传统的基于信息传递的GNNS更强大。石墨-V2比KDD杯2021使用的PCQM4M量子化学数据集中的香草石墨获得的MAE要低得多,后者在这一竞赛中赢得了第一位。与此同时,石墨-V2大大优于最近的“开胃挑战”中的竞争对手,这是NeurIPS 2021研讨会的竞争轨道,目的是用先进的AI模型模拟催化剂-adorbate反应系统。所有模型都可以在\url{https://github.com/microsoft/Graphor}上找到。
