Abstract

fetched live from OpenAlex

When provided with enough labelled training examples, a supervised learning algorithm can learn reasonably accurately. However, creating sufficient labelled data to train accurate classifiers is time consuming and expensive. On the other hand, unlabelled data is usually easy to obtain. This research introduces a novel approach, Guelph Cluster Class (GCC), which improves the task of classification with the use of unlabelled data. The novelty of this approach lies in the use of an unsupervised network, 'Self-Organizing Map', to select natural clusters in labelled and unlabelled data. Sub-classes (made by labelled data) are used to assign labels to unlabelled patterns to produce ' self-labelled' data. The performance of several variants of the GCC system have been obtained by running a 'Back-Propagation' network on labelled and self-labelled data. Results of experiments on several benchmark datasets demonstrate an increasing power for the classification procedure even when the number of labelled data is very small.

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.
