Can my phone AI learn a SPIRAL?FREE

Part 2: the Part 1 brain can't learn a spiral. 24 neurons and more practice, and it bends itself around both arms. Change the numbers and watch it learn.

const c = document.getElementById("c");

// two spiral arms: yellow = 1, blue = 0
const pts = [];
for (let i = 0; i < 100; i++) {
  const a = i / 100 * 9, d = i / 100 * 0.9;
  pts.push([Math.cos(a) * d, Math.sin(a) * d, 1]);
  pts.push([-Math.cos(a) * d, -Math.sin(a) * d, 0]);
}
// a bigger brain: 24 neurons
const H = 24, r = () => Math.random() * 4 - 2;
