Comprehensive pKa Data Augmentation from Limited Real Data through an Engineered Models-Quantum Framework
Researchers have developed a quantum-assisted framework to augment pKa data, addressing the scarcity of tail-region samples in molecular datasets. This approach utilizes extensively optimized machine-learning models for large-scale regression-based pKa prediction and then employs quantum annealing on simulated and physical machines to generate molecules with sparse pKa properties. The method aims to improve molecular modeling and facilitate the discovery of functional molecules with broad-spectrum pKa characteristics, overcoming limitations of traditional continuous latent space VAE-RNN methods.
