Hypothesize, Evaluate, Refine: A Scientific Agent for PDE Discovery with Unknown Spatial Coefficient Fields
AI InsightHER-PDE is the first scientific-agent framework that jointly identifies PDE structure and nonparametric coefficient fields (unknown spatial fields). Unlike prior PDE discovery methods that assume known fields or discover only the operator, it leverages multiple trajectories from different excitations to prevent flexible fields from concealing structural error. This shifts law discovery in heterogeneous media from one-shot optimization to a hypothesize-evaluate-refine agentic loop.Key TakeawayPDE discovery shifts from fixed-field assumptions to joint identification of structure and unknown spatial fields.Why It MattersIn heterogeneous materials, subsurface fluids, and biological tissues, governing laws and medium fields are coupled; reliably recovering both extends the frontier of AI-driven scientific discovery.Who's Affected- AI ResearchersProvides a new paradigm of joint structural-parametric search for scientific discovery agents, transferable to other inverse problems.
- ResearchersPhysicists, materials and earth scientists can automatically discover governing equations in heterogeneous media from noisy data.
- IndustryFields relying on heterogeneous media modeling, such as composite design and hydrocarbon exploration, may shorten manual modeling cycles.
What's NextWatch for generalization to real experimental noise and 3D complex media, and whether joint identification becomes a new standard in PDE discovery benchmarks.Importance 75/100
