【不可忽视的这一种】Dynamic ReLU：自适应参数化 ReLU（调参记录 6）
自适应参数化 ReLU 是一种动态 ReLU（Dynamic ReLU），于 2019 年 5 月 3 日投稿至 IEEE Transactions on Industrial Electronics，于 2020 年 1 月 24 日录用， 于 2020 年 2 月 13 日在 IEEE 官网公布 。
本文冒着过拟合的风险，将卷积核的个数增加成 32 个、64 个和 128 个，继续测试自适应参数化 ReLU 在 Cifar10 上的效果。
自适应参数化 ReLU 的基本原理如下图所示：
Keras 代码如下：
