Abstract
In recent years, data security in organizational information systems has become a serious concern. Many attacks are becoming less detectable by firewall and antivirus software. To improve security, intrusion detection systems (IDSs) are used to detect anomalies in network traffic. Currently, IDS technology has performance issues regarding detection accuracy, detection times, false alarm notifications, and unknown attack detection. Several studies have applied machine-learning approaches as solutions. This study used an ensemble learning approach that integrates the benefits of each single detection algorithms. We made comparisons with seven single classifiers to identify the most appropriate basic classifiers for ensemble learning. The experiment shows logistics regression, decision trees, and gradient boosting are chosen for our ensemble model. The Communications Security Establishment and Canadian Institute for Cybersecurity 2018 (CSE-CIC-IDS2018) dataset was used to evaluate the proposed model. Spearman's rank correlation coefficient facilitated the identification of the data features that might not be used. The experiment results showed that 23 of the 80 features were selected, and the model achieved the following scores: final accuracy, 98.8%; precision, 98.8%; recall, 97.1%; and F1, 97.9%.

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
