    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.

Could be your monitor is old, or your eyes

Oh hey, I can see the gray tails too. It appears when I don't focus on an individual node and try to watch the whole screen.

A three-way adversarial deep neural network learning to draw a cat.

this is clever af
u/BirdsTweetCodersDweet

How is it a neural network? You're just drawing random squares on a cat emoji :P
u/pythech

whoosh
u/magna

Yeah, sorry, it was a bad joke. Just transferring random rectangles from an off-screen canvas. The only catch is the use of valueOf to cut down on the function call ()s.
u/iverjo

Clever indeed!

Sigmoid activation function used in Artificial Neural Networks. Animation shows changes of neural weights plus a random bias.

u/pavel

I often use sigmoids for movement. The ease-out / ease-in looks great. I used 1/(1+1e9**(.5-t%1)) in d/11146 for the 'jumps'.

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()
