来自俄罗斯 Mail.ru 集团、Insilico Medicine 医药公司、莫斯科物理技术学院的研究人员首次尝试利用神经网络研制新的药物。他们试图教会神经网络“思考”并创造出新的分子结构，进而生成一些新的有前景的药物成分。该研究结果发表在《Оncotarget》杂志上。

来自俄罗斯 Mail.ru 集团、Insilico Medicine 医药公司、莫斯科物理技术学院的研究人员首次尝试利用神经网络研制新的药物。他们试图教会神经网络“思考”并创造出新的分子结构，进而生成一些新的有前景的药物成分。该研究结果发表在《Оncotarget》杂志上。


目前人类已知由无机分子构成的物质有上亿种，而这些物质中仅有少量被用于医学。例如，药理学家对已使用多年的阿司匹林进行持续的研究，通过部分改变阿司匹林分子结构，降低其副作用或者提高药效，生产新的药品。

如何从上亿物质中筛选出具有疗效的物质？Insilico Medicine 医药公司及莫斯科物理技术学院的研究人员于 2016 年初开始尝试借助于神经网络完成这个任务，随着研究的深入，研究人员已不仅仅通过神经网络筛选药品成分，而且尝试教会神经网络制造出新的分子结构，从而创造出新的有效药物成分。

研究人员采用了一种竞争性自动编码构架，这是一种网络深入学习新途径的扩充，即用已知疗效的分子结构作为学习教具，将这些已知疗效的分子结构信息输入神经网络，在神经网络学习了大量的此类分子结构信息之后，神经网络开始自动尝试生成分子结构。

训练神经网络的五大算法

神经网络模型的每一类学习过程通常被归纳为一种训练算法。训练的算法有很多，它们的特点和性能各不相同。 问题的抽象 人们把神经网络的学习过程转化为求损失函数f的最小值问题。一般来说，损失函数包括误差项和正则项两部分。误差项衡量神经网络模型在训练数据集上的拟合程度，而正则项则是控制模型的复杂程度，防止出现过拟合现象。 损失函数的函数值由模型的参数（权重值和偏置值）所决定。我们可以把两部分参
