自适应参数化ReLU是一种动态激活函数，对所有输入不是“一视同仁”，在2019年5月3日投稿至IEEE Transactions on Industrial Electronics，2020年1月24日录用，2020年2月13日在IEEE官网公布。

本文在调参记录20的基础上，将残差模块的个数，从27个增加到60个，继续测试深度残差网络ResNet+自适应参数化ReLU激活函数在Cifar10数据集上的表现。

自适应参数化ReLU函数被放在了残差模块的第二个卷积层之后，这与Squeeze-and-Excitation Networks或者深度残差收缩网络是相似的。其基本原理如下

Keras程序如下：

准确率到了95.12%，看来增加深度还是管用的。相较于调参记录20的94.17%高了接近1%。

如果深度再翻倍会怎么样呢？
