Currently, we are using weighted_pick to select outputs:

def weighted_pick(weights):
            t = np.cumsum(weights)
            s = np.sum(weights)
            return(int(np.searchsorted(t, np.random.rand(1)*s)))

Should we also add beam search as an option?

See beam search implementations in Tensorflow tensorflow/tensorflow#654!
