CCB – If that were combined with Chemper-proposed patterns, you might get more reasonable guesses at types
CIB – Agree
DM – GB parameters are a nice toy system, but I’ll be more convinced by bonds. Though I understand that single-atom parameters are easier since there are less degrees of freedom
CIB – Like that this is a good proof of principle. And it’s good that the current direction will hit the “complexity explosion” and naturally need to integrate Chemper to constrain the space of possible SMIRKS eloborations.
DM – TG and I have been looking at separating into gaussians, and using molecules which are in the non-overlapping part of the gaussians to develop types.
CCB – I think Chemper could handle problems at this scale.
CIB – Maybe we could test these proposed solutions by seeing if they could reproduce HJ’s work/decisions over the last year.
CCB – Agree

Physics-based typing with Atoms-in-Molecules and Gaussian mixtures
CIB – I saw Bader talk a few times about his invention of the AIM approach. One interesting thing in the decomposition scheme. You’re trying to bring value by bringing quantum descriptors instead of cheminformatics descriptors. We used the same sort of thing with WBOs (filling in a shortfall of cheminformatics representations using QM information). You’re also looking to bridge the physics and chemistry using clustering schemes. Having tried to do this sort of thing before, I’ve found lots of pitfalls. Could we find a simple toy system for this sort of thing? Maybe JF’s set?
TH – Agree. I was planning to start with LJ type distinction, but I could do GB or charge like JF.
JW – Shared test sets and benchmarking infrastructure?
JF – I agree that it would be efficient in the long run for us to standardize on standard infrastructure and datasets.
