Abstract
This study compares the relative efficiencies (accuracy and computation time) of three versions of the hybrid CK/statistical narrow band method (SNB-CK) for characterizing radiative exchanges in enclosures containing a mixture of non-gray gases (CO2 and H2O). One of these versions, which is characterized by a selective regrouping of bands, leads to very good results while the computation time is significantly decreased with respect to the original SNB-CK version. Complex 2D cases, close to real combustion chambers, are analysed. These cases include irregular geometry and non-uniform concentration and temperature fields. The radiative transfer equation is solved by the discrete ordinates method. The importance of the presence of CO as a third component is also assessed.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
