不行吧,LeakyReLU是不是每个单元的梯度独立随机的?

leaky_relu 我看了下资料和Paddle源码,alpha都是常量呢。麻烦老师详细指点下呢? 倒是有那种randomizd leakyrelu。

不好意思,写错了。是RRelu应该每个单元的梯度独立随机吧

嗯 您说的对,RRelu前向和梯度都是单个单元进行的, 上述代码也是假定的某个单独单元计算逻辑,这里表述得或许不太恰当, 老师,您看这里该怎么写? 去掉这部分内容可以吗, 或者只描述测试阶段的?

LeakyReLU是整层梯度都一样的,不是每个单元(元素),所以这样的模拟并不等价

@zhiboniu 嗯 您说的对,训练阶段不使用leakyrelu, 改成了组合API,辛苦看下。
# 二、飞桨现状 | ||
飞桨目前不支持此功能,但可以基于内置API的方式实现。训练阶段可用paddle.nn.functional.prelu进行模拟,测试阶段可用paddle.nn.functional.leaky_relu模拟。 | ||

这部分说明是组合API的方式,下面5实现方案部分是新增OP的方式。这里内容修改一下吧,注意文档一致性。
下面这段组合实现的代码可以作为一段原理说明保留。

增加paddle.nn. RRelu设计文档。
