…Prevailing RLHF approaches reduce this structure to scalar or pairwise labels, collapsing nuanced preferences into opaque parametric proxies and exposing vulnerabilities to reward hacking . While recent Rubrics-as-Reward (RaR) methods attempt…
…By cascading these adaptive efficiency metrics with a strict correctness gate, our approach effectively avoids the brevity bias associated with absolute penalties and mitigates reward hacking. Extensive experiments on long-horizon benchmarks…
…This reuses the existing answer checker with no auxiliary judge, and, being a difference rather than an absolute probe score, is naturally robust to probe-hacking . The second is the outcome advantage…
…Ultimately, we argue that AI safety audits must evolve to measure real-world leakage propensity, not just worst-case hacks, to give us a true, comprehensive picture of this phenomenon. This is…
…overall, trb seems like a principled bridge rather than a hack, and i can see it being handy for other on-policy setups where teacher signals are noisy early on. Get this…
…i'd love to see an ablation on gating strength across data scales to confirm it's the main driver rather than a stability hack. the arXivLens breakdown helped me parse the…
