本文介绍哈工大团队提出的一种动态ReLU（Dynamic ReLU）激活函数，即自适应参数化ReLU激活函数，原本是应用在基于一维振动信号的故障诊断，能够让每个样本有自己独特的ReLU参数，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。
由于调参记录18依然存在过拟合，本文将自适应参数化ReLU激活函数中最后一层的神经元个数减少为1个，继续测试深度残差网络 自适应参数化ReLU激活函数在Cifar10数据集上的效果。
同时，迭代次数从调参记录18中的5000个epoch，减少到了500个epoch，因为5000次实在是太费时间了，差不多要四天才能跑完。
自适应参数化ReLU激活函数的基本原理如下：
