A Unified Siamese Learning Framework for Zero-Day Anomaly Detection and Classification in Optical Networks
TL;DR
Zero-day anomalies in optical networks pose significant detection challenges due to their unexpected nature. A multi-similarity Siamese neural network was developed to unify zero-day anomaly detection and one-shot classification.
✦ Why It Matters
Engineers can implement this framework to enhance anomaly detection in optical networks without extensive retraining.
Key Takeaways
- Utilize multi-similarity Siamese networks for anomaly detection.
- Achieve high accuracy in classifying unseen anomalies.
- Implement instant adaptability without retraining.
- Enhance network resilience against unexpected disruptions.
Full Summary
Optical networks are increasingly vulnerable to zero-day anomalies, which are unexpected issues that can disrupt service. To address this, a multi-similarity Siamese neural network was created, integrating two tasks: detecting these anomalies and classifying them with minimal examples (one-shot classification).
The methodology involves training the network on various similarity metrics to enhance its ability to recognize and adapt to new anomalies. Results showed that the framework achieved over 99% accuracy in detecting and classifying anomalies, demonstrating its effectiveness.
Importantly, it can adapt to new types of anomalies without requiring retraining, which is a significant advantage in dynamic network environments. This work has implications for improving the resilience and reliability of optical networks, making it easier for engineers to manage unexpected disruptions.
