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 。
在之前的调参记录 18 中，是将深度残差网络 ResNet 中的所有 ReLU 都替换成了自适应参数化 ReLU（Adaptively Parametric ReLU，APReLU）。
由于 APReLU 的输入特征图与输出特征图的尺寸是完全一致的，所以 APReLU 可以被嵌入到神经网络的任意部分。
本文将 APReLU 放在每个残差模块的第二个卷积层之后。这种结构与 Squeeze-and-Excitation Network 是非常相似的，其区别在于 APReLU 额外地包含了非线性变换。
同时，迭代次数也从 5000 个 epoch 减少到了 500 个 epoch。时间耗不起。
APReLU 激活函数的原理如下图所示：
整体代码如下：

Test loss: 0.3449158281087875
Test accuracy: 0.941700000166893相较于调参记录 18 的 94.28%，这次的测试准确率低了一点。
但是，值得指出的是，这次只训练了 500 个 epoch，而调参记录 18 训练了 5000 个 epoch。通过观察 loss 可以发现，其实这次的 loss 下降得更快。
