Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The Shift Toward Open and Reproducible AI Research," Under Review, 2026. doi: 10.48550/arXiv.2606.16974..

| Research Type | Experimental | An illustration of the importance of the infinite-dimensional perspective is provided in Figure 1, which demonstrates that respecting the function space geometry can result in orders of magnitude improvement. Training curves for a PINN for a 2-dimensional Poisson equation; the first order optimizers (Adam and Gradient Descent) plateau, the second-order optimizers (ENGD and Newton) perform much better, but the function-space inspired optimizer (ENGD) reaches the highest accuracy by several orders of magnitude. |
