k_hard_sigmoid

Faster than sigmoid.
Returns <code>0.</code> if <code>x &lt; -2.5</code>, <code>1.</code> if <code>x &gt; 2.5</code>.
In <code>-2.5 &lt;= x &lt;= 2.5</code>, returns <code>0.2 * x + 0.5</code>.

Interface to 'Keras' <https://keras.io>, a high-level neural
networks 'API'. 'Keras' was developed with a focus on enabling fast experimentation,
supports both convolution based networks and recurrent networks (as well as
combinations of the two), and runs seamlessly on both 'CPU' and 'GPU' devices.

k_hard_sigmoid function

This function is part of a set of Keras backend functions that enable
lower level access to the core operations of the backend tensor engine
(e.g. TensorFlow, CNTK, Theano, etc.).
