Abstract

fetched live from OpenAlex

Related research showed that traditional mathematical models have failed to simulate the traffic on the information highway. In contrast to traditional models, the traffic is self-similar or fractal inherently. The Hurst parameter is one very important parameter used to capture this behavior. Tianjin University is currently collaborating with University of Ottawa in the research of self-similarity. This paper summarizes the work done using variance-time plots to estimate the Hurst parameter of real network traffic. Apart from the ordinary conclusion that the network traffic is self-similar, we also made some interesting observations of the multi-fractal behaviour and the value of the Hurst parameter when the traffic is merged. We noted that variance-time plots are not reliable for empirical records with small sample sizes.

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.
