What papers say
Verbatim critique sentences, each from a paper that cites Monte Carlo estimation as a baseline.
“MC estimation typically evaluates only final outcomes, ignoring explicit assessment of intermediate step correctness, which misaligns the supervision signal with the objective of step-wise reasoning accuracy”
— GroundedPRM: Tree-Guided and Fidelity-Aware Process Reward Modeling for Step-Level Reasoning“While Monte Carlo (MC) scores are used as step-wise gold labels, they also introduce substantial noise into the training process.”
— Exploring Generative Process Reward Modeling for Semi-Structured Data: A Case Study of Table Question Answering“they often demand significant computational resources and may produce noisy or unreliable labels, which can degrade model performance”
