Bayesian Belief Network Analysis of a Large Eddy Simulated Ocean Turbulence Field
Bibliographic record
Abstract
An observational space Bayesian belief network analytical formulism is applied to a sub-grid modeled turbulent kinetic energy (tke) field emanating from ocean turbulence large eddy simulation (LES) data containing Langmuir cells but no breaking waves. The purpose of the analysis is to illustrate how statistical machine learning modeling can be used to understand the probabilistic structure of observational space which is needed in demonstrating how the allied latent space can be related statistically to it for the purpose of data generation. The Peter and Clark (PC)-algorithm-based Bayesian belief network (BBN) edge-nodal structure for the observational-space tke subdomains demonstrates a distinctive nonlocal connectivity pattern when the multidimensional scaling graph layout is invoked. When the Chow-Liu algorithm is used, a different tree-based connectivity in the network is revealed. In particular, a dominant parental root node occupies the far upper left region in the observational-space domain with many edge connections flowing toward the right. Quantification of linkage strength through the BBNs provides a way to understand the spatial covariance of observational space subdomains providing hints as to the physically relevant statistical inferential model.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
