Abstract

fetched live from OpenAlex

A polar projection-based algorithm is proposed to reduce the computational complexity associated with dimension reduction in unsupervised learning. This algorithm employs K-means clustering. A new distance metric is developed to account for peak consumption in cluster consumer load profiles. It is used to cluster the load profiles according to both total and peak consumption. To accelerate the clustering process, a stochastic-based approach is developed to reduce the search space to find the cluster centers. Numerical results are presented which show a significant reduction in computational complexity using both polar-based and stochastic-based clustering compared to conventional approaches. Further, the estimation error is low.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
