...数去学习sin（x）就绝不可能有好的成果。 我们还可以偏向性选择机器学习算法。比如我们可以给线性函数加权值衰减（weight decay） λ是为了偏向更小的权重事先选定的参数。当λ为零表示没有偏向。

...展示出，就算是简单的现代算法，不论是监督学习还是增强学习，就已经可以不以设计者的意愿行事了，且是以令人惊讶的方式。 让机器学习模型更稳定的传统技术，比如与权重衰减（weight decay）和dropout，通常不会对“对抗样本”造成实际的防御。

Decoupling weight decay 解耦权重衰减
Finally, several example simulations are made to compare our algorithms with traditional error back propagation, simple weight decay, and relative methods in other paper.
最后通过大量实例仿真将它们与纯误差驱动的方法、权退化法、其它文献中的相关方法进行了比较。
Sweet drinks such as soft drinks, cordial and flavored milk should not be offered to children as they decrease appetite and contribute to tooth decay and weight gain.
甜饮品如软饮料、甜香酒和风味牛奶等会减少食欲、加快牙齿腐蚀和肥胖，不应该给孩子食用。
The three original EdgeRank elements - Affinity, Weight and Time Decay - are still factors in News Feed ranking, but "other things are equally important," he says.
而这三个最基础的权重因素就是亲密度、权重、时间衰减。
