Leaky ReLu is nothing more than an improved version of the ReLU activation function. As mentioned in the previous section, using ReLU may “kill” some neurons in our neural network and these neurons may never become active again. Leaky ReLU was defined to solve this problem. Web使用Leaky ReLU的好处就是:在反向传播过程中,对于Leaky ReLU激活函数输入小于零的部分,也可以计算得到梯度(而不是像ReLU一样值为0),这样就避免了梯度方向锯齿问题。 α的分布满足均值为0,标准差为1的正态分布,该方法叫做随机Leaky ReLU(Randomized Leaky ReLU)。 rockaway hills ranch
