Description:
 def LReLU_function( signal, derivative=False, leakage = 0.01 ):
 """ Leaky Rectified Linear Unit """

    if derivative:
        # Return the partial derivation of the activation function
        return np.clip(signal > 0, leakage, 1.0)
    else:
        # Return the activation signal
        output = np.copy( signal )
        output[ output < 0 ] *= leakage
        return output
