A First Glance at Jev for Network Traffic Classification: Accuracy, Processing Time, and Cost

Read the original on arXiv Machine Learning →

The paper evaluates Jev, a general-purpose decision model, for classifying network traffic using only the first ten packets’ sizes, directions, and inter‑packet times. Across 52,000 records, adding 40 labeled examples improves Jev’s accuracy from 9.80% to 28.42%, yet Random Forest and Extra Trees models trained on 8,000 records achieve higher accuracies of 69.95% and 66.80%. Even with 150 examples, Jev reaches only 34.50% accuracy, and in a paired 100‑record test, Jev’s 29% accuracy and 0.750 s median request time are lower than the generative OpenAI GPT‑5.6 Sol’s 37% accuracy and 6.036 s response time, though Jev incurs lower API charges.

Jev-IDS: System One Models for Network Intrusion Detection

JEV-IDS is an open experimental general network intrusion detection system that uses the Jev System One Model to detect zero‑day intrusions even when labeled data are scarce. The system processes one flow per request and asks the model two questions: a binary attack probability and a finite‑choice traffic category. In tests on a 300‑flow NSL‑KDD pilot split, JEV-IDS achieved an F1‑score of 0.859, precision of 0.941, recall of 0.790, and a novel‑attack recall of 0.838, while being 4.8 times faster and 3.8 times cheaper than GPT‑5.6 Luna and producing 15 times fewer false alarms than a low‑data Random Forest.

HydroJEV: A one-second, training-free screen for cyber-attack and fault attribution in water distribution networks

HydroJEV is a training‑free, one‑second model that classifies SCADA alarms in water distribution networks into cyberattack, physical fault, normal transient, or faulty sensor. In a benchmark on the C‑Town EPANET network, HydroJEV matched a hand‑written rule tree and outperformed a supervised classifier, especially when few labeled events were available, while being 20‑40 times faster than large language models. When combined with a rule tree gate, it reduced the need for human review by about a third without sacrificing accuracy.

JevForest: Path Voting for Budgeted Feature Acquisition

JevForest is a feature‑acquisition policy that aggregates path‑dependent proposals from bootstrapped trees, weights them by global training information gain, and uses a shared masked classifier to predict from the acquired values. In online experiments, a four‑question forest on AG News achieved 0.729 accuracy versus 0.667 for a static gain ranking and 0.583 for random ordering, while on TREC the ordering reversed. Offline MiniBooNE tests showed accuracies of 0.845 with ten features and 0.885 with forty features, indicating that Jev’s effectiveness varies with task, predictor, and budget constraints.
