A meta-learning approach for selectivity prediction in asymmetric catalysis - Nature Communications The need for large amount of experimental data can present a bottleneck for implementing machine learning models. Here, the authors propose a meta-learning workflow that can harness the literature-der...

Singh & Hernández-Lobato introduce meta-learning for predicting enantioselective outcomes in catalytic hydrogenations. Their approach quickly adapts to new reactions—often outdoing standard ML—using only minimal data. A leap forward in asymmetric catalysis. www.nature.com/articles/s41...
