Abstract

fetched live from OpenAlex

With advances in technology, high volumes of a wide variety of valuable data of different veracity can be easily collected or generated at a high velocity in the current era of big data. Embedded in these big data are implicit, previously unknown and potentially useful information. Hence, fast and scalable big data science and engineering solutions that mine and discover knowledge from these big data are in demand. A popular and practical data mining task is to group similar data into clusters (i.e., clustering). To cluster very large data or big data, k-means based algorithms have been widely used. Although many existing k-means algorithms give quality results, they also suffer from some problems. For instance, there are risks associated with randomly selecting the k centroids, there is a tendency to produce roughly equal circular clusters, and the runtime complexity is very high. To deal with these problems, we present in this paper a big data science and engineering solution that applies heuristic prototype-based algorithm. Evaluation results show the efficiency and scalability of this solution.

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.
