    I found his paper: https://iopscience.iop.org/article/10.3847/1538-3881/ad7fe6 (no paywall 😃)

    From the intro:

    VARnet leverages a one-dimensional wavelet decomposition in order to minimize the impact of spurious data on the analysis, and a novel modification to the discrete Fourier transform (DFT) to quickly detect periodicity and extract features of the time series. VARnet integrates these analyses into a type prediction for the source by leveraging machine learning, primarily CNN.

    They start with some good old fashioned signal processing, before feeding the result into a neutral net. The NN was trained on synthetic data.

    FC = Fully Connected layer, so they’re mixing FC with mostly convolutional layers in their NN. I haven’t read the whole paper, I’m happy to be corrected.











  • The source story is worth a read.

    Marrero’s background is in Navy intelligence, and she earned a master’s degree in business administration with a concentration in information security and digital management

    Incredible.

    she soon changed the “STINKY” Wi-Fi network name to another moniker that looked like a wireless printer — even though no such general-use wireless printers were present on the ship

    Why not just switch off broadcasting the SSID?

    [The CO and XO] then conducted another sweep inside the ship. Although the network that appeared to be a wireless printer appeared on their personal devices during their search, neither made additional inquiries regarding that network

    No-one’s coming out of this looking good.

    Marrero’s secret Starlink dish was removed the same day, and Marrero told another unidentified crew member the next day that it was authorized for in-port use — prompting sailors to re-install the illegal Starlink.

    It just keeps going!
