OpenAI math findings withdrawn over sign error that Astra failed to catch
A sign error caused three withdrawals in OpenAI's mathematical findings compilation, and asking Astra to audit the specified section did not catch it; human experts spotted the flawed proof strategy instead.
Gentle reminder that the sign error that caused 3 withdrawals in the mathematical findings compilation by @OpenAI could not be probed by just asking Astra to audit the article, even specifying the section. Indeed, the correction came from humans who found the entire proof strategy suspect. The proof strategy involves constructing "flexible" Lagrangians inside symplectic manifolds that are obstructed in Lagrangian Floer homology. This immediately fires up red flags in any experts' mind: loose Legendrians having vanishing Floer invariants. Cutting humans out of the loop gives way for proof-destroying errors of such magnitude to go unchecked. Now extrapolate such blunders to biotech research, where formal verifications aren't available (even in math, they had Lean, but sheer negligence made them assume a Bayesian epsitemology precludes major errors).
