DECS NRP Detector
This repository contains the NRP (Necessary Reasoning Prefix) detector model used in the DECS algorithm, as presented in the paper Overthinking Reduction with Decoupled Rewards and Curriculum Data Scheduling.
The NRP detector is designed to determine whether a given reasoning chunk contains the ground truth signal, enabling surgically precise token-level rewards to reduce "overthinking" in reasoning models.
