Here's a good function header given the following:
I wrote the below code

    def rbm_fe(rbm_params, v, b):
        (weights, visbias, hidbias) = rbm_params
        vis_term = (b * tensor.dot(v, visbias))
        hid_act = (b * (tensor.dot(v, weights) + hidbias))
        fe = ((- vis_term) - tensor.sum(tensor.log((1 + tensor.exp(hid_act))), axis=1))
        return fe
    fe_a = rbm_fe(rbmA_params, v_sample, (1 - beta))
    fe_b = rbm_fe(rbmB_params, v_sample, beta)
    return (fe_a + fe_b)

What's a good function header?
