Abstract

fetched live from OpenAlex

The University of Calgary has conducted a number of ground-penetrating radar (GPR) surveys at the Maya archaeological site of Ma'ax Na since 2001. In an attempt to assist archaeologists working at the site, our research has focussed on improving the quality of the GPR images, highlighting any anomalous features and discerning near-surface stratigraphy. Several 2-D lines and two 3-D grid surveys were acquired across a Maya plaza complex using Sensors and Software's Noggin@ and Smart Cart@ System with antennae frequency of 250 MHz. The hyperbolic fitting of curves to point diffractors indicates significant differences in velocities between field seasons. We attribute this to varying climatic conditions (dry in 2003, wet in 2002). Measured velocities in 2002 ranged from .072 - .lo6 mlns, while velocities ranging from 0.122 - 0.140 mlns were found in 2003. Standard seismic processing algorithms and programs were adapted to the GPR data. The application of a processing flow resullted in improved resolution and continuity of events on the GPR. records. A GPR synthetic radargram was generated based on archaeological information from an excavated pit. Interpretation of the GPR images across the plaza has highlighted a number of interesting features.

Full frame distilled prediction

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.
