X-Blocks: Linguistic Blocks for AV Explanations
💡91% accurate LLM framework decodes AV explanation linguistics—vital for XAI in driving (68 chars)
⚡ 30-Second TL;DR
What Changed
Hierarchical X-Blocks framework analyzes explanations at context-syntax-lexicon levels
Why It Matters
Provides evidence-based principles for scenario-aware NLG in AVs, boosting trust and transparency. Dataset-agnostic design extends to other safety-critical AI domains like robotics.
What To Do Next
Apply RACE framework with open LLMs to classify explanations in your AV dataset.
Key Points
- •Hierarchical X-Blocks framework analyzes explanations at context-syntax-lexicon levels
- •RACE multi-LLM classifier hits 91.45% accuracy and 0.91 Cohen's kappa on DeepDrive-X
- •Log-odds with Dirichlet priors reveals scenario-specific vocabulary patterns
- •Dependency parsing extracts reusable grammar templates varying by predicate and causal types
