N厂沛纳海ETA6947机芯怎么样

在以前的参数记录18中，深度误差网络ResNet中的所有ReLU都被自适应参数化ReLU(自适应参数化ReLU，APReLU)所取代。

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：

自适应参数化ReLU激活函数

整体代码如下：

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。
