Learning Randomized Reductions

arXiv:2412.18134v4 Announce Type: replace Abstract: Randomized self-reductions (RSRs) express $f(x)$ using $f$ evaluated at random correlated points, enabling self-correcting programs, instance-hiding protocols, and applications in complexity theory and cryptography. Yet discovering RSRs has required manual expert derivation for over 40 years, limiting their practical use. We present Bitween for automated RSR learning. First, we formalize RSR learning with sample complexity analysis under correlated sampling. Second, we develop Vanilla Bitween, which integrates multiple backends (linear regres

Why this matters
Why now

The accelerating pace of AI development and the increasing complexity of AI systems necessitate automated methods for discovering fundamental algorithmic structures like Randomized Self-Reductions.

Why it’s important

Automating the discovery of Randomized Self-Reductions (RSRs) promises to unlock new capabilities in cryptography, complexity theory, and self-correcting programs, which have been historically bottlenecked by manual derivation.

What changes

The ability to automatically learn RSRs will transition this field from artisanal, expert-driven derivation to scalable, AI-driven discovery, greatly expanding its practical applications.
