Abstract
Kernel machines have been successfully applied to many engineering problems requiring pattern recognition and regression. Kernel machines are a family of machine learning algorithms including support vector machines (SVM) [1], kernel least mean squares adaptive filter (KLMS) [2], and kernel recursive least squares (KRLS) adaptive filter [3] to name a few. In this paper we present the partitioned kernel machine algorithm for use in online learning in virtual environments. The PKM algorithm enhances the accuracy of the computationally efficient KLMS algorithm. The PKM algorithm is an iterative update procedure that focuses on a subset of the stored vectors in the kernel machine buffer. We use a similarity measure for the selection of kernel machine vectors that allow more common vectors to be updated more frequently, and outlier vectors to be updated less frequently. We validate the increased accuracy of our novel algorithm in two separate experimental settings.

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
