VGB Algorithm Fixes Catastrophic Error Compounding in Long-Form Generation
arena · x · 2026-08-22
Standard inference-time sampling methods (e.g., rejection sampling, best-of-n) can fail catastrophically during long generations due to compounding errors, even with a near-perfect verifier.
@AShettyV discusses VGB (Value-Guided Backtracking), a provably more robust fix rooted in sampling theory that addresses these errors.
