摘要:

迁移学习的成功已经推广了一些方法,这些方法涉及从大量数据源中预训练模型,然后针对特定任务进行微调。虽然这种方法已经成为自然语言处理等领域的标准,但化学迁移学习方法的实施和评估仍处于早期阶段。在这项工作中,我们展示了在包含270万个水簇的分子数据库上训练的图神经网络(GNN)的下游任务的微调。使用Graphcore IPU作为训练分子GNN的AI加速器,将训练时间从0.5M集群上的2.7天减少到2.7M集群上的1.2小时。在单个GPU上,微调分子动力学下游任务的预训练模型和转移到不同的势能表面分别只需8.3小时和28分钟。

英文摘要:

The demonstrated success of transfer learning has popularized approaches that involve pretraining models from massive data sources and subsequent finetuning towards a specific task. While such approaches have become the norm in fields such as natural language processing, implementation and evaluation of transfer learning approaches for chemistry are in the early stages. In this work, we demonstrate finetuning for downstream tasks on a graph neural network (GNN) trained over a molecular database containing 2.7 million water clusters. The use of Graphcore IPUs as an AI accelerator for training molecular GNNs reduces training time from a reported 2.7 days on 0.5M clusters to 1.2 hours on 2.7M clusters. Finetuning the pretrained model for downstream tasks of molecular dynamics and transfer to a different potential energy surface took only 8.3 hours and 28 minutes, respectively, on a single GPU.
