“AI detectors” like lie detectors is a pseudoscience. Casting aspersions without definitive proof should be treated as defamation with the legal ramifications thereof

On AI capabilities: the French press is all over the Haitian-Canadian novel C’était ça ou mourir. It's winning basically every award you can win, and was tipped to be the 2nd Canadian winner of the Prix Goncourt. Only one problem: 1/2

@masoka_siphiwe Standard template used in my research group. Not sure of the why, but interchangeable with “Supervised by”. The dissertation was evaluated by external examiners. Stephen was my Supervisor

@Iam_LucTheDon What I can say is it was 3 DJI models + another I can’t remember . A 4th got stolen from our lab

[Thithiba @ZamuGoci]

@Iam_LucTheDon Robust. We evaluated against UAVs (and other flying objects) unseen in the training data. I deliberately had multiple drones to fly to avoid model bias

@Iam_LucTheDon One last thing: you can then build and train an AI classifier model (CNN) on the radar spectrogram data

[Thithiba @ZamuGoci]

@Iam_LucTheDon The technical detail of how this all works will take too long to explain 😅. But I hope that gives you the gist

[Thithiba @ZamuGoci]

@Iam_LucTheDon We can then do experiments to produce a rich radar dataset of drones, birds, balloons etc and compute their spectrograms. Build a AI model to classify them based on the computed spectrogram

[Thithiba @ZamuGoci]

@Iam_LucTheDon Good Q. The short answer is drones are not a single rigid body in flight. The propeller blades have their own rotational motion. With that, we can exploit the micro-Doppler effects that emerge as a result of the blades. TBC…

BREAKING: Israel’s criminal invasion of Rafah, the last place of refuge for Palestinians in Gaza, has begun.

1.7 million civilians trapped in Rafah are now being attacked through air, land and sea, in the middle of the night.

My parents are visiting me here in Cape Town (they're based in the Northern Cape). They bought some biltong and droëwors here. I've never seen people more disgusted 😭😭 They were not happy at all.
