    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.

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'.

u/metamero

nice, Gabe! i'm glad you're using the remix feature and making experiments, modding other dweets and referencing then at the same time. on dwitter soon we learn more then we thought we could. keep coding, you're welcome!

Nicee
u/Ath0r

Thanks! It's the first time I've tried, so probably I missed a lot of tricks to reduce characters... Any feedback or tips are welcome! :D
u/13thptr

b is unused so you can remove it :)

nice dweet btw

Thanks a lot for the suggestions, @13thptr! Indeed, I forgot to remove the unused b and the characters you remove by avoiding the definition of p is also very nice :)
