GradIEEEnt half decent: The hidden power of imprecise lines

Ғылым және технология

Before the invention of KZread comments, most people could make remarks that were slightly technically incorrect without fear of immediate public rebuke. The one exception was professors, especially if the classroom included an annoying student such as “Tom 7.” The invention of KZread was doubly revolutionary: Now anyone can experience being a professor being corrected by an annoying student, but also, corrections can be made years after the fact, and at significant length, as the student cannot be told to “take this offline.” This video is such a lengthy correction and digression, and perhaps itself a fount of mistakes.
Due to the esoteric detail and prodigious whiteboarding, it is almost a “Tom Academy” video. But since I grew a moustache to film it, it qualifies for the Main Sequence.
Keywords: Gradient descent, half-precision floating point, linear operations, F=MA, rounding, exotic transfer functions, machine learning, MNIST, CIFAR-10, chess, fractals, Frobenius, cryptography, fluint8, Motorola 6502.
For SIGBOVIK 2023.
Paper, impenetrable code, etc.: tom7.org/grad/

    Atari 2600 is tiny, but the code in atari 2600 games is so precisely written that if you sneeze on it it breaks completely. The 2600 had CPU-drive graphics. And I don't mean like the ZX80 where games would write to VRAM at their leisure, and then later on the CPU would push those VRAM bits out to the screen - the 2600 doesn't have enough RAM for that. No, I mean that, when it came time to draw the screen to the TV, a 2600 game would *use game logic to render a scanline of graphics in real-time as the beam crosses the screen.* It would do this for every scanline. It would use most of the CPU's time (leaving the vblank period for higher level game logic, a reversal of the typical arrangement), and if code wasn't tuned perfectly it would completely break. There wasn't enough RAM to do anything else, nothing ever did anything like that ever again, and its one of the craziest ways to render a game ever conceived. Meanwhile, anybody who's watched a Vinny corruption stream knows how much you can break an NES game and still have it keep on going.

    I wish to see you getting nerd-sniped by this and somehow do floating point maths with analogue waves or something, maybe even build a whole (super basic) computer using the weird differentiator and integrator components. As a starting seed, note that you can get ln through integrating 1/x, and through ln you can get abs(x), and through that you can practically make arbitrary circuit. Don't know how useful or practical this is, but hey, maybe you end up discovering something video-worthy. I have some more ideas btw, mainly stemming from trying to (ab)use Desmos to define Boolean algebra and, hence, to create functions for equality and less than etc so that I'm able to define piecewise functions without any piecewise notation. I'd share a link to that here but KZread is fussy about links.

That's actually a somewhat standard trick, e.g. to get root-mean-square averages in an analog way. Analog computers were/are a thing, just that noise+imprecision limits the amount of stages you can cascade, and therefore the amount of cool stuff you can practically do And getting piecewise linear functions is pretty easy with step(x) = abs(x)/x ;) Used tricks like this to write text as graphs of functions on my calculator in boring math classes, the fun part is getting two lines above each other (interleaved with sign(sin(N * x)) or so)

From the changelog: "An evaluation of +1 is now no longer tied to the value of one pawn, but to the likelihood of winning the game. With a +1 evaluation, Stockfish has now a 50% chance of winning the game against an equally strong opponent. This convention scales down evaluations a bit compared to Stockfish 15 and allows for consistent evaluations in the future."

    I was actually just at an academic conference where a similar problem was discussed! (The paper is Model Checking Linear Dynamical Systems under Floating-point Rounding at TACAS 2023) The authors want to verify certain linear programs, but find that with rounding it is undecidable for the same reasons as Tom: They can construct a computer. Their computer is a Turing machine, which I think we can all agree is much simpler than the NES, but it's the same idea. They go on to show that restricting the programs to non-negative coefficients makes the problem decidable again, because it forces the behavior to be somehow periodic.

    I would guess that a lot of the operations will turn out to just be the zero function, or just some small constant, because a lot of the time we are trying to eliminate everything except for the error (in order to magnify it and use it). But by doing that with precise linear operations, everything would exactly cancel out. It's hard to know if this would eventually result in the overall matrix being the zero matrix, or just some very degenerate matrix, or maybe I'm completely wrong in assuming this at all.

    ​​@@jamesflames6987 don't worry, I was already fully aware of the problems of floating point math in programming, and had solved that previous problem by going down a really convoluted path with integer math. I'm not doing stuff with money or anything super critical though, I'm slowly trying to make my own paragliding flight instrument, which means figuring out sensor fusion with a 9-axis IMU, GPS, barometer, thermometer, and eventually a Pitot tube for airspeed. Because I want to learn how it all works, I'm trying to do it all from scratch, writing my own Kalman filters or whichever type I go with, for example. There will be regions of this project where making somewhat fuzzy comparisons of floating point numbers will be useful and sufficiently accurate. That's an excellent warning for people who aren't aware of the pitfalls of float math, though!
