How to implement PReLU activation in Tensorflow?
<p>The <a href="https://arxiv.org/pdf/1502.01852v1.pdf" rel="noreferrer">Parametric Rectified Linear Unit</a> (PReLU) is an interesting and widely used activation function. It seems that Tensorflow (<a href="https://github.com/tensorflow/tensorflow/blob/r0.11/tensorflow/python/ops/nn.py#L17" rel="noreferrer">reference link</a>) does not provide PReLU. I know that the higher level libraries, such as <a href="https://keras.io/activations/#on-advanced-activations" rel="noreferrer">Keras</a> and <a href="http://tflearn.org/activations/#prelu" rel="noreferrer">TFLearn</a>, has the implementation of it.</p>

<p>I would like to know how to implement <strong>PReLU</strong> in <strong>Tensorflow</strong>?</p>
