Abstract

Chemically accurate and comprehensive studies of the virtual space of all possible molecules are severely limited by the computational cost of quantum chemistry. We introduce a composite strategy that adds machine learning corrections to computationally inexpensive approximate legacy quantum methods. After training, highly accurate predictions of enthalpies, free energies, entropies, and electron correlation energies are possible, for significantly larger molecular sets than used for training. For thermochemical properties of up to 16k isomers of C7H10O2 we present numerical evidence that chemical accuracy can be reached. We also predict electron correlation energy in post Hartree-Fock methods, at the computational cost of Hartree-Fock, and we establish a qualitative relationship between molecular entropy and electron correlation. The transferability of our approach is demonstrated, using semiempirical quantum chemistry and machine learning models trained on 1 and 10% of 134k organic molecules, to reproduce enthalpies of all remaining molecules at density functional theory level of accuracy.

  • Δ-learning is typically computationally much more efficient than training an NNP directly using only data from a high-level method, because the correction (Δ-) surface is expected to be much smoother than the full potential energy surface.

    “Δ-learning is typically computationally much more efficient than training of an NNP directly using only data from a high-level method. The reason is that the correction- (Δ-) surface is expected to be much smoother than the full potential energy surface.”

    From A reactive neural network framework for water-loaded acidic zeolites (2024) · cites this paper as [33]

    The Conclusions (pp. 7–8) report that Δ-ML lowers the computational cost of high-level predictions and that the remaining deviations are smaller and possibly smoother. The Results (p. 3) also report that Δ-ML models outperform a baseline-free ML model trained directly on target energies. But the paper uses kernel ridge regression, not an NNP, and does not establish that training Δ-learning is typically more computationally efficient than training a high-level NNP or that its correction potential-energy surface is smoother than the full surface.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
