Comparative Analysis of Agent Evaluation Frameworks: Stability, Detection, and Discovery in Enterprise Analytics Agents
Story 19, from arXiv
A study compares three evaluation frameworks for LLM-based analytics agents, finding that trace-based evaluation offers the best balance of precision and recall, while adversarial red-teaming is better for uncovering novel risks.
Key points
- Three evaluation frameworks are compared: trace-based LLM judging, text-only LLM judging with red-teaming, and deterministic heuristics.
- Trace-based evaluation achieved the best precision-recall balance (F1=0.90) on known risks, while text-only evaluation had 5x more false alarms.
- Unknown risks were uncovered by combining functional testing and security red-teaming, with no overlap between the two.
- Stability of evaluation frameworks was found to be agent-independent, with 97% of configurations meeting the stability threshold.
- LLM-based evaluation frameworks can detect subtle errors that human reviewers miss.
- The study recommends using two frameworks: trace-based for functional assessment and adversarial red-teaming for security validation.
Why it matters
As enterprises deploy LLM-based analytics agents, reliable evaluation is critical to ensure correctness and security. This study provides actionable insights into which evaluation strategies are most effective for different types of risks.
Counterpoint
The study is limited to a controlled research setting with frozen execution traces, which may not fully represent real-world deployment scenarios.
