Abstract

fetched live from OpenAlex

Vector parabolic equation (VPE) methods have been widely applied to model wave propagation in guiding structures with high accuracy and computational efficiency. A detailed specification of the modeled environment is required. However, considerable uncertainty can exist in the description of the environment. This paper presents a non-intrusive formulation of polynomial chaos expansion (PCE) method to quantify the uncertainties in VPE-based channel models for tunnel environments. The performance is validated against Monte Carlo simulations and measurements.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
