Abstract
The swift expansion of online textual data has rendered text classification increasingly vital in information management. Despite the prevalent usage of the chi-square test in text classification, there has been a scarcity of thorough research regarding its specific uses in recent years. Therefore, it is vital to encapsulate the research about the use of the chi-square test in text classification throughout the last five years. This report reviews the application of the chi-square statistic in Arabic text classification, social media data analysis, and medical literature classification and analyses its effectiveness in feature selection and enhancing classification performance. By reviewing and analyzing the academic literature, this report summarizes the application of improved chi-square feature selection methods to different text data types. It explores the effectiveness of these methods in improving classification accuracy. The findings indicate that chi-square has significant advantages in text classification in different domains, especially when dealing with complex linguistic texts and user-generated content.

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 it
