Implements the Sigmoid Linear Unit (SiLU) or swish function
Parameters:
vector (np.array): A numpy array consisting of real
values.
vector (np.ndarray): A numpy array consisting of real values
Returns:
swish_vec (np.array): The input numpy array, after applying
swish.
swish_vec (np.ndarray): The input numpy array, after applying swish
Examples:
>>> sigmoid_linear_unit(np.array([-1.0, 1.0, 2.0]))
