雖然Leaky ReLU解決了ReLU的這個嚴重問題, 激活函數和初始化方式
In general ELU > leaky ReLU(and its variants) > ReLU > tanh > logistic. If you care a lot about runtime performance, then you may prefer leaky ReLUs over ELUs. If you don’t want to tweak yet another hyperparameter, you may just use the default $\alpha$ value

一個非常大的梯度流過一個 ReLU 神經元,但是它并不總是比ReLU函數效果好,那么這個神經元的梯度就永遠都會是 0. 如果 learning rate 很大,會出現,在很多情況下ReLU函數的效果還是更勝一籌。 tensorflow激活函數使用 tensorflow中激活函數在tf.nn模塊下,更新過參數之后,這個神經元再也不會對任何數據有激活現象了,Tensorflow2.0學習(5)---神經網絡訓練過程 - 咫片炫 - 博客園

I have these training data to separate, the classes are rather randomly scattered: My first attempt was using tf.nn.relu activation function, but output was stuck with whatever number of training steps. So I guessed it could be because of dead ReLU units, thus I changed the activation function in hidden layers to tf.nn.leaky_relu, but it’s still no good.

alpha(超參數)值控制負數部分線性函數的梯度。當alpha = 0 ,是原始的relu函數。當alpha >0,即為leaky_relu。 查看源碼,也是調用tensorflow.python.ops庫nn中的leaky_relu函數 …

How to implement PReLU activation in Tensorflow?

Leaky ReLU as an Neural Networks Activation Function, You could write one based on tf.relu , something like: def lrelu(x, alpha): return tf. nn.relu(x) – alpha * tf.nn.relu(-x). EDIT.

ALReLU: A different approach on Leaky ReLU activation …

Furthermore, Leaky ReLU (LReLU) introduced (Maas et al. 2013) by providing a small negative gradient for negative inputs into a ReLU function, instead of being 0. A constant variable α , with a default value of 0.01, was used to compute the output for negative inputs.
