    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.

Gradient Descent (iterative) algorithm used to calculate sqrt(2). The big dots are the two roots -sqrt(2) and +sqrt(2) of equation Y=X**3-X*2. The Gradient Descent is an optimization algorithm for finding a local minimum of a function near a starting point, taking successive steps in the direction of the negative of the gradient. x[n+1]=x[n]−η(∇f)xn where η is the "Learning Rate". Gradient Descent is widely used for training Machine Learning models. #neural #ai

u/rodrigo.siqueira

Simple version that calculates sqrt(2). If you change initial "x" to -1, it will converge to -sqrt(2), that is the other root of the equation Y=X**3-X*2. Code: x = 1; learning_rate = .1; for(i=0;i<50;i++) { x = x - learning_rate * (x**3 - 2*x) } throw(x);

The model is text encoded like:d/28296, saved in localstorage. This dweet basically searches the prompt in the model and outputs the line where it is. Pro tip: replace eval with throw and get the uncompressed code. TL;DR: There is no AI in it, it uses my own "nano-Wikipedia" and searches in it.

procedural javscript gibberish generator #ai

u/timothytomato

change the string in a=this.a||'dwitt' to something else for different gibberish. it works by comparing the current character with document.body.innerHTML and predicting what the next character should be, so kind of like a really bad autocomplete.
