Joint discovery of governing partial differential equations from multi-source datasets by competitive optimization
arXiv:2606.30699v1 Announce Type: new Abstract: Discovering governing equations directly from observational data is a key step towards interpretable scientific machine learning. Current data-driven approaches typically operate on a single dataset, inherently limiting their performance when faced with restricted observations. In practice, multiple datasets are often available for the same physical system, distinguished only by distinct initial conditions or boundary configurations. Here, we present a competitive optimization framework designed to discover shared partial differential equations (
The proliferation of various scientific data sources and advancements in AI/ML techniques for scientific discovery are converging, creating an opportune moment for more sophisticated data integration methods.
This development could significantly accelerate scientific discovery and engineering innovation by enabling AI to uncover fundamental physical laws more robustly and efficiently from diverse datasets.
AI's ability to 'learn' governing equations from multiple, heterogeneous datasets will improve, leading to more accurate and generalizable scientific models across various domains.
