UNSUPERVISED TRANSFORMER SIGNAL SEPARATION
This abstract first appeared for US patent application 20250146861 titled 'UNSUPERVISED TRANSFORMER SIGNAL SEPARATION
Original Abstract Submitted
systems and methods include collecting vibration data along an optical fiber cable using distributed acoustic sensing (das). the collected vibration data is preprocessed to separate the vibration data into at least two mixtures. the at least two mixtures are combined into a mixture of mixtures. the mixture of mixtures is separated into a plurality of estimated source signals using a separation model. the separation model is trained using an unsupervised loss computed between the estimated source signals and the at least two mixtures.
