# tf.nn.relu leaky tf.nn.leaky_relu

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

tf.nn.leaky_relu
tf.nn.leaky_relu( features, alpha=0.2, name=None ) Defined in tensorflow/python/ops/nn_ops.py. Compute the Leaky ReLU activation function. “Rectifier Nonlinearities

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.
