A Novel Kernelized Classifier Based on the Combination of Partially Global and Local Characteristics.
Bibliographic record
Abstract
The Kernel Support Vector Machine (KSVM) has achieved promising classication performance. However, since it is based only on local information (Support Vectors), it is sensitive to directions with large data spread. On the other hand, Kernel Nonparametric Discrimi- nant Analysis (KNDA) is an improvement over the more general Kernel Fisher Discriminant Analysis (KFD), where the normality assumption from KFD is relaxed. Furthermore, KNDA incorporates the partially global information in the Kernel space, to detect the dominant nor- mal directions to the decision surface, which represent the true data spread. However, KNDA relies on the choice of the -nearest neighbors ( NN 's) on the decision boundary. This paper introduces a novel Combined KSVM and KNDA (CKSVMNDA) model which controls the spread of the data, while maximizing a relative margin separating the data classes. This model is considered as an improvement to KSVM by incorporating the data spread information represented by the dominant normal directions to the decision boundary. This can also be viewed as an extension to the KNDA where the support vectors improve the choice of -nearest neighbors (

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.
