Figure shows a flow chart of our proposed approach that would be implemented for a calculation of the H-matrix. As usual the starting point is the restricted basis for the calculation of the H-matrix. at a minimum the excitation space would have to be severely limited. However, even with the evaluating the matrix elements by even the most efficient quadrature methods would be prohibitive in 24 dimensions. This fact notwithstanding, it does appear that the ML approach here will be powerful means to avoid calculating very small matrix elements. And, based on the empirical evidence given here and the discussion above, the number of elements increases rapidly with the number of degrees of freedom. Thus, the ML method proposed will become even more "needed" and effective as a means to deal with this rapid increase.
