Prediction of non-stationary functional data: Universal Kriging in a Hilbert space
Bibliographic record
Abstract
In an increasing number of studies, collected data are curves; when functional data are spatially dependent, the problem of prediction assumes a key role. In this work we deal with spatially distributed functional data proposing an extension of some geostatistical tools to non-stationary functional random fields, with a Functional Data Analysis approach. An extension of the Universal Kriging method to elements of a Hilbert space is proposed, in a coherent frame of definitions and assumptions. \nConsistently with these new theoretical results, a method for prediction of non-stationary spatial dependent functional data is proposed and then developed in three steps: model selection for the drift term, decomposition of the original process into a deterministic term (the drift) and a residual stochastic process, Universal Kriging prediction. \nThe proposed procedure is applied to daily mean temperatures curves observed in 35 meteorological stations located in Canada's Maritimes Provinces.

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.
