Fully Unsupervised Detection of Physical Contacts on Subsea Cables via State-of-Polarization MonitoringAgastya Raj, Alvaro Doval, Tian Tian et al.
We present a fully unsupervised Fast-Slow DSVDD detector for continuous State-of-Polarization monitoring on a deployed subsea cable. Trained without event labels, it ranks all five confirmed trawler contacts within the top 13 of 122,174 recordings and surfaces additional corroborated cable-contact events.
