Abstract
Network intrusion detection systems (NIDS) face the growing difficulty posed by increasingly sophisticated and unseen attacks, which represent a dangerous threat due to their ability to exploit vulnerabilities that have not yet been identified. These attacks are inherently difficult to detect with conventional NIDS because such systems typically are built on known threat patterns or signatures, which are absent in unseen scenarios. Consequently, this greatly limits their efficacy in mitigating advanced threats, making networks susceptible to potential security breaches. To address these challenges, recent years have witnessed the emergence of various Reinforcement Learning (RL) approaches aimed at enhancing the automatic detection of network intrusions. These systems are equipped with autonomous agents that acquire the ability to learn independently and make decisions without requiring direct input or knowledge of human experts. In this paper, we propose a network intrusion detection mechanism that integrates a Deep Q Network-based model (DQN) with a supervised machine learning algorithm specifically designed for attack classification. Our model is characterized by meticulous fine-tuning of hyperparameters to optimize the performance of detection. Extensive experimental evaluations that take advantage of the NSL-KDD and CSE-CICIDS2017 datasets demonstrate that our hybrid approach significantly improves detection accuracy across various types of attack and outperforms other existing state-of-the-art solutions designed for similar purposes.

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
