Research on semi-supervised manifold regularization algorithm to detect application layer DDoS attack
Bibliographic record
Abstract
The existing detection methods of application layer of distributed denial of service(DDo S) attack are based on the statistical characteristic of user browsing behavior to distinguish the abnormal user and normal users, and because the calculation time and space complexity of high-level protocol parsing and deep packet processing are very high, it is very difficult to realize online detection. Aiming at the small samples of Web DDo S attacks, a semi-supervised manifold regularization detection method was proposed. Firstly, Web log was filtered into a 14 dimensional feature spaces according to IP address or domain name within a time window to describe the user's access behavior. Secondly, Laprls least-square algorithm based on semi-supervised manifold regularization was designed to classify the small sample data in the feature space so that the abnormal user could be distinguished from normal users. Finally, through the experimental analysis, the algorithm was contrasted with other algorithms in terms of adaptability of small samples and usage of unlabelled samples. The results show the proposed algorithm has higher classification accuracy compared with other algorithms such as SVM, RLS and K-NN in terms of Web DDo S attack detection, which shows that a semi-supervised manifold regularization of Laprls least-square algorithm has better practicability for detecting Web DDo S attack.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
