Verifiers as Scoring Models vs. Binary Classifiers

Training a Reward Model as a Verifier

Choosing a Method for an LLM Reasoning Checker

A research team is tasked with creating a system to automatically evaluate the quality of reasoning paths generated by a language model. They are considering two primary strategies for their 'verifier' component:

Strategy 1: Develop a detailed algorithm with a set of pre-defined logical rules and patterns to check each step of the model's output during inference.

Strategy 2: Collect a large dataset of reasoning paths, have human experts label each path as 'high-quality' or 'low-quality', and then train a separate model on this labeled data.

Based on the predominant and most scalable approach for this task, which strategy should the team choose and why?

Verifiers as Binary Classifiers

The most common and scalable method for creating a system that validates a language model's reasoning involves developing a complex set of predefined, heuristic rules that check the model's output as it is being generated.
