Researchers have developed a new on-the-fly multifidelity machine learning framework designed to optimize data generation for quantum chemistry calculations. This adaptive approach dynamically selects training samples at different fidelity levels, prioritizing lower-cost data until model accuracy is maximized before moving to more expensive, high-fidelity data. Benchmarked against existing methods, the adaptive framework significantly reduces data generation costs, achieving up to a 30-fold improvement over single-fidelity methods and a 5-fold improvement over standard multifidelity approaches, paving the way for more efficient and cost-aware machine learning in the field.
