 where :math:`V_2(r_{ij})` and :math:`V_3 (r_{ij},r_{ik},r_{jk})` are the two- and three-body interactions, respectively. For the two-body the summation is over all neighbours J and for the three-body the summation is over all neighbors J and K of atom I within a cutoff distance determined from the potential files. :math:`B_n(r_{ij})` are the cubic bspline basis, :math:`c_n` and :math:`c_{l,m,n}` are the machine-learned interaction parameters and :math:`N`, :math:`N_l`, :math:`N_m`, and :math:`N_n` denote the number of basis functions per spline or tensor spline dimension.
