Inverting the Shield: Systematically Generating Safety Tests from Policy Specifications
TL;DR
Existing safety evaluation methods for Large Language Models (LLMs) are limited by expert knowledge and lack systematic guarantees. POLARIS, a new framework, converts natural-language policy specifications into First-Order Logic (FOL) representations, enabling systematic safety testing.
✦ Why It Matters
Engineers can leverage POLARIS to enhance the safety testing of AI systems systematically and effectively.
Key Takeaways
- Utilize POLARIS for systematic safety testing of LLMs.
- Transform natural-language policies into formal logic for better traceability.
- Explore the Semantic Policy Graph to identify violation patterns.
- Achieve higher policy coverage compared to traditional safety evaluation methods.
How It Works
POLARIS begins by converting unstructured natural-language policies into First-Order Logic (FOL), which allows for precise formalization of rules. This process creates a Semantic Policy Graph, where each node represents a policy rule and edges represent potential violations.
By traversing this graph, POLARIS systematically identifies complex violation scenarios and generates corresponding test cases in natural language, ensuring that safety evaluations are both comprehensive and reproducible.
