Constellation diagrams for spectrum anomaly detection in optical networks
Accurate and efficient anomaly detection is a key enabler for the cognitive management of optical networks, but traditional anomaly detection algorithms are computationally complex and do not scale well with the amount of monitoring data. Therefore, this dataset enables research on new optical spectrum anomaly detection schemes that exploit computer vision and deep unsupervised learning to perform optical network monitoring relying only on constellation diagrams of received signals. A scheme implemented over this dataset achieves 100% detection accuracy even without prior knowledge of the anomalies. Furthermore, operation with encoded images of constellation diagrams reduces the runtime by up to 200 times. Further research can focus on the efficiency of the algorithms, as well as exploit new ML algorithms, anomaly identification, etc.
The dataset contains a set of folders, each one representing one normal/anomalous case.
Within each folder, a number of .mat files contain the raw data collected from VPITransmissionMaker. The images folder contains the rendered constellation diagrams.
To render your own constellation diagrams, check the "generate_plots.m" file in the root folder.
