Prediction of 1H NMR chemical shifts using neural networks.

TL;DR: Counterpropagation neural networks were applied to the fast prediction of 1H NMR chemical shifts of CHn groups in organic compounds, and some stereochemical effects could be correctly predicted.
Journal ArticleDOI

Machine Learning Methods to Predict Density Functional Theory B3LYP Energies of HOMO and LUMO Orbitals.

TL;DR: Inclusion of the orbital energy calculated by PM7 as an additional descriptor significantly improved the quality of estimations (reducing the MAE in >30%) and the impact of the quantum chemical calculation protocol was assessed with a subset of compounds.
Journal ArticleDOI

Estimation of melting points of pyridinium bromide ionic liquids with decision trees and neural networks

TL;DR: In this paper, regression trees were built with an initial pool of 1085 molecular descriptors calculated by DRAGON software for 126 pyridinium bromides, to predict the melting point.
