A Functional Data Classification Model Utilizing Functional Mahalanobis Distance and Regenerative Kernel Methods
Bibliographic record
Abstract
The classification of functional data is an important research direction in modern data mining. In this paper, we propose a similarity measurement method for functional data based on functional Mahalanobis distance and regenerative kernel theory, considering the scenario where the predictor variable is a random function and the response variable is a categorical scalar. This method is then applied to functional kernel principal component analysis. During the classification phase, classic algorithms such as support vector machines and random forests can be combined to accomplish the task of classifying functional data. In empirical analysis, compared to the regenerative kernel based on Euclidean distance and the Euclidean distance regenerative kernel based on B-spline basis functions, the proposed method achieves better classification results. Furthermore, this similarity measurement can also be utilized in other machine learning algorithms based on regenerative kernel theory, thereby developing corresponding analysis methods for functional data.

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.
