PGVP is a simple diagnostic protocol that reliably distinguishes true periodic generalization from spurious curve fitting, ensuring models are structurally validated before deployment.
PGVP is a simple diagnostic protocol that reliably distinguishes true periodic generalization from spurious curve fitting, ensuring models are structurally validated before deployment.
The PGVP project (Periodic Generalization Verification Protocol) develops a diagnostic framework that detects when neural networks achieve near‑perfect accuracy in‑domain but collapse under periodic out‑of‑distribution shifts; it is led by independent researcher Mohamed Samir Abd Elrahman Selim in Cairo, Egypt, and has advanced to the stage of published experiments and open‑access dissemination showing that standard MLPs fail catastrophically while Fourier‑based models generalize reliably — see the permanent archive [https://doi.org/10.5281/zenodo.18576471], researcher profile [https://orcid.org/0009-0001-2930-3609], and Google Scholar record [https://scholar.google.com/citations?user=IrKSLv0AAAAJ].
By exposing spurious periodic generalization before deployment, PGVP directly reduces catastrophic AI risk: models that appear perfect in‑domain but collapse under structured shifts are precisely the ones that can trigger systemic failures in medicine, finance, or infrastructure. Detecting this failure mode early prevents brittle systems from being trusted in high‑stakes contexts, which in turn avoids cascading errors (misdiagnoses, economic miscalculations, safety‑critical malfunctions). The causal chain is clear — PGVP identifies unreliable generalization → unreliable models are flagged or rejected → only structurally validated models reach deployment → deployment risk is reduced → catastrophic or existential harms from advanced AI are mitigated.
