Abstract

fetched live from OpenAlex

Wastewater treatment is a complicated process where sensors and equipment are operated at harsh conditions, and there are often long time delays in variables' response to disturbances. In this work, support vector machine is applied to diagnose fault. Because of the unbalanced distribution of the fault classes data quantity or importance, the risk functional R WLOO(α) with weight coefficient based on leave-one-out errors is presented; then Genetic Algorithms (GA) is used to globally optimize the risk functional R WLOO(α). Because of the size of the data is large, we present a simple algorithm of R WLOO(α) to reduce the amount of calculation. The improved SVM is used to classify dataset of WWTP, and the results indicate that compared with the standard SVM and BP neural network (NN), the improved one can gain higher classification accuracy.

Full frame distilled prediction

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.
