Summary
This post from the Papers.Cool deep-dive series on zhichai.net highlights two notable AI papers. The first, X-RAY: Mapping LLM Reasoning Capability via Formalized and Calibrated Probes, dissects large language model reasoning using formalized probes. It reveals a 'cognitive asymmetry' in LLMs—they are robust to constraint refinement but fragile under solution-space reorganization—and can distinguish models that standard benchmarks cannot separate, going beyond simple correctness evaluation to explain why models succeed or fail. The second, PACE: A Personalized Adaptive Curriculum Engine for 9-1-1 Call-taker Training, uses contextual bandits to personalize training scenarios for emergency call-takers. Reported results include a 19.5% reduction in training time, decision time dropping from 11.58 minutes to 34 seconds (a 95% reduction), and 95.45% agreement with expert judgment. Together, the posts illustrate both AI interpretability research and AI-human collaboration applied to life-saving emergency response training.

Paper 1: X-RAY — When AI Learns to Self-Examine
Paper: X-RAY: Mapping LLM Reasoning Capability via Formalized and Calibrated Probes
Key findings:
- Uses formalized probes to "dissect" the reasoning process of LLMs
- Reveals a "cognitive asymmetry" in LLMs — robust to constraint refinement, but fragile when the solution space is reorganized
- Can distinguish between models that standard benchmarks fail to separate
Why it's interesting: It doesn't just evaluate whether an answer is right or wrong — it looks inside to understand *why* it is right or wrong.

Paper 2: PACE — An AI Coach on the Front Line of Life and Death
Paper: PACE: A Personalized Adaptive Curriculum Engine for 9-1-1 Call-taker Training
Core results:
- Uses contextual bandits to recommend personalized training scenarios
- 911 call-taker training time reduced by 19.5%; decision time cut from 11.58 minutes to 34 seconds (a 95% reduction)
- 95.45% agreement with expert judgment
Why it's interesting: The algorithm directly serves life-saving work — a model example of AI + human collaboration.
