JAF: Judge Agents for Continuous AI Improvement

A new approach to improve the reasoning abilities of AI agents has been presented in a recent arXiv paper. The framework, called JAF (Judge Agent Forest), introduces the use of judge agents that evaluate the responses generated by a primary agent, not in isolation, but in relation to a set of related queries.

The key idea is that by jointly analyzing the responses to similar queries, the judge agent can identify patterns and inconsistencies that would otherwise go unnoticed. This collective feedback allows the primary agent to improve its deliveries, learning from a broader perspective.

JAF Architecture and Operation

JAF is based on principles of belief propagation and ensemble learning. Overlaps between different contexts create a knowledge graph structure that facilitates the propagation of critique. Repeated and randomized evaluations generate a robust ensemble of context-sensitive judgments.

The framework uses a locality-sensitive hashing (LSH) algorithm to select relevant examples to use in the evaluation process. This algorithm integrates semantic embeddings, LLM-driven hash predicates, supervision from categorical labels, and other relevant information to create informative binary codes. These codes support efficient, interpretable, and relation-aware selection of diverse exemplars, further optimizing the exploration of CoT (Chain of Thought) reasoning paths.

Empirical Validation

The effectiveness of JAF has been validated through an empirical study on the triage of cloud misconfigurations in large-scale cloud environments. The results demonstrate that JAF can significantly improve the performance of AI agents in this complex task.
