    Just to warn you there is a lot of lore and it’s changed and been retconned over the last 40 years. That leads to some odd stuff like Leman Russ having a tank named after him.

    It’s also had some major tone shifts from silly (Inquisitor Obiwan Sherlock Cluseau ) to so Grim Dark it becomes Grim Derp. It’s in a sort of midpoint now.

    So look into what you find interesting and if you don’t like it switch sources or topic. Expect things to be contradictory depending on when it was written.

    Here is a good but silly video background to the origin of the orks. It’s still mostly accurate. In 30k the Emperor got hurt and was put on a life support chair. He’s been there for 10k years unable to communicate.

    Premise of this series is they install a text to speech device and now big E can communicate. So they update him on the state of the Imperium and he fills in all the missing history. It’s a fan video and noncannon but lore accurate for when it was made.

    If you want a more serious tone for your lore dump try luetin09 or oculus imperialis. They are to dry for me but pretty good content.

    Also WAAGH is the ork war cry and WAAGH energy is the reality bending field that makes the orks group think real. So red things go faster because red is the fastest color.






  • The solution for this is usually counter training. Granted my experience is on the opposite end training ai vision systems to id real objects.

    So you train up your detector ai on hand tagged images. When it gets good you use it to train a generator ai until the generator is good at fooling the detector.

    Then you train the detector on new tagged real data and the new ai generated data. Once it’s good at detection again you train the generator ai on the new detector.

    Repeate several times and you usually get a solid detector and a good generator as a side effect.

    The thing is you need new real human tagged data for each new generation. None of the companies want to generate new human tagged data sets as it’s expensive.

    Yeah. The thing that made me “get” quaternions was thinking about clocks. The hands move around in a 2d plane. You can represent the tips position with just x,y. However the axis that they rotate around is the z axis.

    To do a n dimensional rotation you need a n+1 dimensional axis. So to do a 3D rotation you need a 4D axis. This is bassicly a quat.

    You can use trig to get there in parts but it requires you to be careful to keep your planes distinct. If your planes get parallel you get gimbal lock. This never happens when working with quats.

    No. It’s more what the previous poster said about encoding rotation. It’s just not a xyz axes. It’s current, charge, flux as axes. The trig is how you collapse the 3d system into a 2d or 1d projection. You lose some information but it’s more useful from a spefic reference.

    Without complex numbers you can’t properly represent the information.

    Yup. When you have a circuit that is not purely resistive the inductive or capacitive load causes the voltage and current to not be in phase. It looks like ohms law is being violated. However the missing part of the energy is in the imaginary component to be returned latter.
