This was just a fun thought experiment.

Feed it two inputs (e.g. chance of rain and wind speed; this is one of the examples in the demo) and it learns to answer a yes/no question like "bring an umbrella?" It's a one-neuron binary classifier with three learned parameters: two weights and a bias. Those three numbers map directly to Red, Green, and Blue. Save the model: you get a 1x1 PNG. Load the pixel: you get your classifier back. The color is the model.

It is fun. The trainer seems to get stuck in local minima though.

Tried again and no. To reproduce create a corridor e.g.

    X    O
    
     X     O

      X   O
       X     O

       X   O
Line can get jammed in non vertical positon.

Increased default epochs to 2000 instead of 500, I think that fixed it but let me know if you still run into this.
