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. x: A 2D context for that canvas.

  • rodrigo.siqueira: 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
  • 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);

  • katkip: I tried to make a similar algorithm to the linear regression algorithm! Machine learning #ai prediction inside dwitter! If you think this doesn't deserve an awesome, search on google what is linear regression ;) I couldn't golf all the formulas so I used the mean calculus. z=Math.random;if(!t){X=[],Y=[],Q=0,W=0;for(i=10;i--;)X.push(z()*960),Y.push(z()*960);for(p in X)Q+=X[p],W+=Y[p],x.fillRect(X[p],Y[p],9,9);x.moveTo(0,0);x.lineTo(Q/5,W/5)}x.stroke()

  • pavel: Js puts all vars into global namespace if you don't use 'var' or 'let' and t starts at 0 so you can do t?a.map(...):a=[...]

  • katkip: It's not deep learning but I will #ai this.
  • iverjo: My cat reacts to this ^^ She tries to catch the "fishes"
