SS-ESOAP: Self-Scaled Adaptive Preconditioning for Physics-Informed Learning
AI InsightSS-ESOAP augments SOAP preconditioning with a scalar secant-energy correction and adaptive basis update, targeting ill-conditioned PINN objectives. It achieves the lowest final residual on 6 of 8 PDE benchmarks, improving convergence accuracy over SOAP without global state overhead.Key TakeawayCompared to SOAP, adds scalar secant correction and adaptive basis update, improving PDE benchmark accuracy.Why It MattersPINN training suffers from ill-conditioning; this method improves accuracy while retaining SOAP scalability, potentially advancing physics-informed learning for scientific computing.Who's Affected- AI ResearchersGain a SOAP-drop-in optimizer variant with improved accuracy for PDE-related tasks.
- DevelopersCan integrate SS-ESOAP into existing PINN frameworks, reducing tuning overhead.
- IndustryScientific computing and engineering simulation benefit from more efficient physics-informed training.
