softmax函数的硬件实现

softmax作用

首先我们简单的介绍一下我们使用softmax的用处，以及softmax的函数形式。softmax在维基百科上面的解释是：“softmax function is a generalization of the logistic function that maps a length-p vector of real values to a length-K vector of values”简单的说它是一种适用于多分类的损失函数。公式表示如下：

我们可以看到，要使用硬件去实现softmax函数首先必须硬件实现exp(x)。实现指数函数的思路是什么呢？首先，我们可以使用泰勒级数展开，那么为了保持一定的精度我需要使用很多的乘法器所以每一个指数函数都需要耗费大量的时钟周期，所以说我们还是选择比较简单的分段线段拟合比较好。下面提供我的思路：我使用分段的线段去拟合softmax函数，当然在硬件实现之前我做了很多关于阈值还有精度对神经网络训练精度的实验发现缩小softmax的输入压缩到一定的阈值比如(-10,10)发现对训练正确率的影响很小。那么我可以使用一个ROM来存储线段的K，B，在计算的时候每一个指数函数我都只需要一个乘法器就能计算。这样大大提高了计算速度。（需要注意的是：我们的硬件结构计算全部使用的是十六位浮点型数据，做乘除法的时候只需要调用IP核就行了）
