Abstract
Text document classification (TDC) is an approach used for the classification of any kind of document for the target category or out.Text classification algorithms have come across significant challenges recently as a result of the exponential expansion of digital text documents; the large volume of words in each document reduces the effectiveness of these existing text classifiers.A key method for improving classification accuracy and getting rid of redundant data is referred to as feature selection (FS).In this work, several phases have been conducted to test and equip the proposed model.Initially, the applied machine learning algorithms were tested and trained using the Reuters-21578 dataset.Second, data cleaning, label encoding, tokenizing, text cleaning, and last TF-IDF vectorization were done to prepare the dataset.Thirdly, four distinct machine learning algorithms, Extreme Gradient Boosting (XGBoost), K-Nearest Neighbor (KNN), Random Forest (RF), and Decision Tree (DT) were used to build a brand-new machine learning-based text document classification model (ML-TDCM) for document classification.Finally, several metrics, including F1 score, accuracy, precision, and recall, were used to assess the proposed model.With a 91% classification accuracy, XGBoost turned out to be the best-performing algorithm among the others.The obtained results were also matched with results obtained in past studies, verifying the performance of the suggested models and so defining them as possible methods to be applied in the next work concerning document categorization.

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
