PREVISOR SVR-LSSVR WAVELET NA PROJEÇÃO DE SÉRIES TEMPORAIS
Bibliographic record
Abstract
Na literatura, e bem conhecido que o s metodos preditivos (ou previsores) support vector regression (SVR) e least square support vector regression (LSSVR) consistem em alternativas eficientes na projecao de series temporais (estocasticas) e que a decomposicao wavelet oferece vantagens atrativas no processo preditivo. Assim o sendo, utilizando programacao nao linear e combinacao linear de previsoes, propoe-se neste artigo um previsor hibrido que integra as seguintes abordagens: SVR, LSSVR e decomposicao wavelet. A fim de ilustra-lo, e utilizada a serie temporal Canadian lynx. Os resultados alcancados pelo previsor hibrido proposto alcancou maior nivel de acuracia que dezoito metodos competitivos.

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.
