Abstract

fetched live from OpenAlex

Due to the diversity of sources, a large amount of data is being produced and also has variousproblems including mislabeled data, missing values, imbalanced class labels, noise and highdimensionality. In this research article, we proposed a novel framework to address highdimensionality issue with feature reduction to increase the classification performance of variouslazy learners, rule-based induction, bayes, and tree-based models. In this research, we proposedrobust Quarter Feature Selection (QFS) framework based on Symmetrical Uncertainty AttributeEvaluator. Our proposed technique analyzed with Six real world datasets. The proposedframework , divide whole data space into 4 sets (Quarters) of features without duplication. Eachsuch quarter has less than or equals 25 % features of whole data space. Practical results recordedthat, one of the quarter, sometimes more than one quarter recording improved accuracy than thealready available feature selection methods in the literature. In this research, we used filter-basedfeature selection methods such as GRAE, IG, CHI-SQUARE (CHI 2), Relief to compare thequarter of features produced by proposed technique.

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.
