Abstract

fetched live from OpenAlex

Data mining aims to search for implicit, previously unknown, and potentially useful pieces of information---such as sets of items that are frequently co-occurring together---that are embedded in data. The mined frequent sets can be used in the discovery of correlation or casual relations, analysis of sequences, and formation of association rules. Since its introduction, frequent set mining has been the subject of numerous studies. Most of these studies find all the frequent sets from transaction databases of precise data, in which items within each transaction are definitely known and precise. However, there are many real-life situations in which the user is interested in only some tiny portions of the entire frequent sets, and there are also many situations in which data in the transaction databases are uncertain. This calls for both (i) constrained frequent set mining (which finds frequent sets that satisfy user constraints indicating the user interest) and (ii) frequent set mining from uncertain data. In this paper, we propose a tree-based system that integrates these two kinds of frequent set mining. The resulting mining system avoids candidate generation; it pushes the user constraints inside the mining process, which avoids unnecessary computation. Consequently, the system effectively mines from transaction databases of uncertain data for only those frequent sets satisfying the user-specified constraints.

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.
