Abstract

fetched live from OpenAlex

Many digital signal processing algorithms are based on mono-scale analysis. Since the reshuffling of any data value does not change the probability distribution, the sense of correlation or covariance in the data is lost, especially when dealing with self-affine time series. An alternative approach is to use poly-scale analysis. This paper describes two poly-scale algorithms: the length fractal dimension and variance fractal dimension and evaluates their accuracy and precision. First, we generate white Gaussian noise and fractal Brownian motion using the concepts of fractional Brownian motion and the discrete Fourier transform. Next, we evaluate the performance of these measures. Since many processes are nonstationary, we also present a stationarity-frame detection technique based on the One-Way ANOVA and Bartlett tests. Our results show that these poly-scale techniques can always be used as reliable tools for different purposes in self-affine data analysis.

Teacher imitation

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.
