- 权重衰减:在机器学习和神经网络中,一种正则化技术,通过在损失函数中添加一个正则化项来减小权重的大小,以防止过拟合。
1 ?权值衰减 ...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。 2 ?权重衰减 ...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。

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。 - 2
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。 - 3
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。
