Manuscript for first EAGER grant paper on Bayesian inference driven force field parameterization using a multi-fidelity likelihood calculation algorithm
Test container to display in-progress machinery for using amortized inference to refit the 4-D C-C & C-H LJ parameters (to scale up) from the smirnoff99Frosst
forcefield. We are training solely on molar volume and heat of vaporization from cyclohexane.
