Abstract

fetched live from OpenAlex

In this paper, we propose a novel multiple model prediction approach using a genetic algorithm (GA). The motivation relies on the fact that many real-life time series cannot be accurately described by a single dynamic model because these time series are composed of more than one underlying regimes along the time scale. Based on a hidden Markov process, the proposed multiple model (MM) is able to capture the temporal relationship among the underlying regimes. A genetic algorithm is employed to train the multiple model and to obtain an optimal segmentation of the time series. Combined with a nonlinear prediction method, this named GA MM predictor is also proposed to identify systems with input signals composed of multiple chaotic dynamics. Applied to a newly developed time division multiuser chaotic communication system, the GA MM approach provides satisfactory channel equalization performance even when the measurement noise is strong.

Not 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.
