SAHOO: Safeguarded Alignment for High-Order Optimization Objectives in Recursive Self-Improvement
It addresses alignment preservation during recursive self-improvement for AI systems, making it measurable and deployable, though it appears incremental as it builds on existing monitoring and control methods.
The paper tackles the problem of alignment drift in recursive self-improvement systems by introducing SAHOO, a framework with safeguards that achieved substantial quality gains, including 18.3% improvement in code tasks and 16.8% in reasoning, while preserving constraints.
Recursive self-improvement is moving from theory to practice: modern systems can critique, revise, and evaluate their own outputs, yet iterative self-modification risks subtle alignment drift. We introduce SAHOO, a practical framework to monitor and control drift through three safeguards: (i) the Goal Drift Index (GDI), a learned multi-signal detector combining semantic, lexical, structural, and distributional measures; (ii) constraint preservation checks that enforce safety-critical invariants such as syntactic correctness and non-hallucination; and (iii) regression-risk quantification to flag improvement cycles that undo prior gains. Across 189 tasks in code generation, mathematical reasoning, and truthfulness, SAHOO produces substantial quality gains, including 18.3 percent improvement in code tasks and 16.8 percent in reasoning, while preserving constraints in two domains and maintaining low violations in truthfulness. Thresholds are calibrated on a small validation set of 18 tasks across three cycles. We further map the capability-alignment frontier, showing efficient early improvement cycles but rising alignment costs later and exposing domain-specific tensions such as fluency versus factuality. SAHOO therefore makes alignment preservation during recursive self-improvement measurable, deployable, and systematically validated at scale.
