2.5-D Decomposition for LLM-Based Spatial Construction
Paul Whitten, Li-Jen Chen, Sharath Baddam - accepted to NAECON 2026

A neuro-symbolic pipeline where the LLM plans in the 2D horizontal plane while a deterministic executor computes vertical placement, removing a whole class of errors by design.

Explainability Methods for Hardware Trojan Detection: A Systematic Comparison
Paul Whitten, Francis Wolff, Chris Papachristou - accepted to the Journal of Electronic Testing (Springer Nature)

A systematic comparison of three categories of explainability for gate-level hardware trojan detection on the Trust-Hub benchmark: domain-aware property-based analysis, model-agnostic case-based reasoning, and model-agnostic feature attribution (LIME, SHAP, gradient).
