A dynamic regularized Gaussian radial basis function network for nonlinear, nonstationary time series prediction
Bibliographic record
Abstract
A dynamic network of regularized Gaussian radial basis functions (GaRBF) is described for the one-step prediction of nonlinear, nonstationary autoregressive (NLAR) processes governed by a smooth process map and a zero-mean, independent additive disturbance process of bounded variance. For N basis functions, both full-order and reduced-order updating algorithms are introduced, having computational complexities of O (N/sup 3/) and O (N/sup 2/), respectively, per time step. Simulations on a 10,000 point, 8-bit quantized 64 k bps rate speech signal show that the proposed dynamic algorithm has a prediction performance comparable and, in some cases, superior to that of AT&T's LMS-based speech predictor designed for the ITU-T G.721 standard on the 32 kbps ADPCM of speech. The results indicate that the proposed dynamic regularized GaRBF predictor provides a useful tradeoff between its minimal need for prior knowledge of the speech data characteristics and its consequently heavier computational burden.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
