Abstract

fetched live from OpenAlex

Data mining is the process of automatic classification of cases based on data patterns obtained from a dataset. A number of algorithms have been developed and implemented to extract information and discover knowledge patterns that may be useful for decision support. Once these patterns are extracted they can be used for automatic classification of case mixes. Although research has been conducted using diverse algorithms on small datasets (of about ten to fifteen attributes), in this paper, for the first time, we make use of a large database, namely, the interRAI Minimum Data Set for Mental Health (MDS-MH) containing over 455 attributes. Several data mining algorithms were used to classify clinical cases using MDS-MH data. The algorithms included Bayes methods, association rules, decision trees, and clustering. We compare these algorithms in various classification tasks and identify advantages and disadvantages of each algorithm with respect to their accuracy and use.

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.
