New research questions effectiveness of RLVR data decontamination methods

By PulseAugur Editorial · [1 sources] ·

A new paper published on arXiv evaluates the effectiveness and costs associated with data decontamination methods for Reinforcement Learning with Verifiable Rewards (RLVR) math corpora. The study audited sixteen corpora against six benchmarks, assessing eight decontamination policies using exact, lexical, and semantic matching. Results indicate that current semantic matching policies often lead to false removals of data, with one tested policy achieving 98.1% resolved precision and 98.2% candidate-frame recall, demonstrating a more favorable balance than alternatives.

    What Should We Remove? Evaluating the Reliability and Costs of RLVR Data Decontamination

    arXiv:2610.21229v1 Announce Type: new Abstract: Reinforcement learning with verifiable rewards (RLVR) math corpora are routinely screened for benchmark overlap, but the reliability and data-loss costs of cleaning policies remain underexamined. We audit sixteen open RLVR math corp…
