摘要:

我们提出了面向化学分类任务的elEmBERT模型,该模型基于多层编码器架构等深度学习技术构建。我们在有机、无机及晶体化合物数据集上验证了该方法的应用潜力,具体使用包含晶体性质与药物设计相关任务的Matbench(材料基准)和Moleculenet(分子基准)基准数据集开发并测试模型。我们还对化合物的向量表示进行分析,揭示结构数据中的潜在模式。该模型展现出卓越的预测能力,且普遍适用于分子与材料数据集,例如在Tox21数据集上取得了96%的平均精度,较此前最优结果提升了10%。

英文摘要:

We introduce the elEmBERT model for chemical classification tasks. It is based on deep learning techniques, such as a multilayer encoder architecture. We demonstrate the opportunities offered by our approach on sets of organic, inorganic and crystalline compounds. In particular, we developed and tested the model using the Matbench and Moleculenet benchmarks, which include crystal properties and drug design-related benchmarks. We also conduct an analysis of vector representations of chemical compounds, shedding light on the underlying patterns in structural data. Our model exhibits exceptional predictive capabilities and proves universally applicable to molecular and material datasets. For instance, on the Tox21 dataset, we achieved an average precision of 96%, surpassing the previously best result by 10%.
