摘要:

我们描述了一个完全数据驱动的模型,该模型学习执行逆合成反应预测任务,该任务被视为序列到序列映射问题。端到端训练模型具有由两个递归神经网络组成的编码器-解码器架构,该架构先前在解决其他序列到序列预测任务(如机器翻译)方面取得了巨大成功。该模型基于来自美国专利文献的50,000个实验反应示例进行训练,这些示例涵盖了药物化学家常用的10种广泛的反应类型。我们发现,我们的模型执行与基于规则的专家系统基线模型,并克服了某些限制与基于规则的专家系统和任何机器学习方法,包含一个基于规则的专家系统组件。我们的模型提供了一个重要的第一步,解决具有挑战性的问题,计算逆合成分析。

英文摘要:

We describe a fully data driven model that learns to perform a retrosynthetic reaction prediction task, which is treated as a sequence-to-sequence mapping problem. The end-to-end trained model has an encoder-decoder architecture that consists of two recurrent neural networks, which has previously shown great success in solving other sequence-to-sequence prediction tasks such as machine translation. The model is trained on 50,000 experimental reaction examples from the United States patent literature, which span 10 broad reaction types that are commonly used by medicinal chemists. We find that our model performs comparably with a rule-based expert system baseline model, and also overcomes certain limitations associated with rule-based expert systems and with any machine learning approach that contains a rule-based expert system component. Our model provides an important first step towards solving the challenging problem of computational retrosynthetic analysis.
