In this thread post links to books, videos, MOOCs, tutorials, forums, and general learning resources about creating robots (particularly humanoid robots), writing AI or other robotics related software, design or art software, electronics, makerspace training stuff or just about anything that's specifically an educational resource and also useful for anons learning how to build their own robowaifus. >tl;dr ITT we mek /robowaifu/ school.

Found this book to be a good introduction to robotics. Plus, guys look up the "A Manga Guide to -" series of mangas. A good intro to any maths or science field you're just entering.

>>30903 its like you would expect, the closer you get to zero the smaller your delta gets so if you just take a guess and keep adding the change to your answer eventually you will just stop moving which is your root

Robowaifu Technician 04/14/2024 (Sun) 11:46:52 No.30908
>>30907 its also really simple to program if you want to play around with it, its how sqrt() is done when the cpu doesnt have a math chip void main() { float guess = 13; float ans = guess; // newtons method formula = x - f(x)/`f(x) // using f(x)= 3x^3 + 5x^2 - 3x - 2 // `f(x)= 9x^2 + 10x - 3 for ( int i=0; i<50; i++ ) { float fx = 3*(ans*ans*ans) + 5*(ans*ans) - 3*ans - 2; float dfx = 9*(ans*ans) + 18*ans - 3; float guess = ans - (fx / dfx); if ( guess == ans ) break; ans = guess; printf( "i=%d \t x=%f \n", i, ans ); } printf( "final answer = %f \n", ans ); } you only get a root though like this function has 3 but you have to play with the initial guess to get them otherwise you just get which evers closest, fun stuff

>>30909 meant to be 10*ans not 18*ans my bad, good mistake to see how the method works though since you still center in one of the roots even though the derivative is wrong it just takes more iterations lots of things you can do to make it better of course just wanted to keep it simple

>>30910 Ahh, thanks. It's rather nice that the eminent Newton devised such a computationally-simple approach to this need. I'm sure with modern superscalar architectures, the solution would converge in very few clocks. Cheers. :^)

This well-accomplished Frenchman seems oddly opposed to the GH's typical agendas regarding AI -- though he himself being deeply entrenched in the GH Big-Tech world.
