CIGA+ : an Algorithm for Computing a Concise Set of Frequently closed Item Sets
Bibliographic record
Abstract
Since the output of a data mining task can be very large even for a reasonably small data set, the objective of the present paper is to describe an approach which reduces the data mining output and hence the execution time by approximating the set of frequent closed itemsets. More precisely, an algorithm called CIGA+ (Closed Itemset Generation and Approximation) is proposed and aims at partial or complete generation of frequent closed itemsets ( FCIs ) based on the construction and exploration of a dependency graph. The degree of approximation (eventually null) depends upon the value assigned to two parameter thresholds : cooccurrence frequency between two individual items and tolerance. Experimental analysis of our approach illustrates its cost-effectiveness and its potential for efficient association rule mining. Moreover, a comparative study with an existing and efficient algorithm for mining FCIs shows that CIGA+ has good performances even for large and dense data sets.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
