MetJam: Metamorphic Testing for Data Synthesize and Quality Assurance of an ML-based Jamming (DOS) Detector in 5G
Bibliographic record
Abstract
Traditionally, metamorphic testing is an approach for quality assurance engineers to generate test cases with oracles for purposes of assuring the functional correctness of a system under test. We provide an argument for utilizing the metamorphic testing technique for the purpose of domain and application specific data synthesis for machine-learning systems, and we propose a process for creating and maintaining a library of metamorphic relations that concisely captures subject matter expert knowledge about classification boundaries in a way that is easy for them to understand and manage. As is typical in machine-learning applications, synthesized ground truth data of the sort can be useful both for training and testing. We illustrate and evaluate the method in an application to detect stealthy host-initiated denial of service or jamming, showing the method can be used to improve attack detectors through training and identify weaknesses through validation.

How this classification was reachedexpand
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.
