Artificial Neural Networks for lua

[SirRanjid]

Added rotation and some better coloring.

Overfitting in motion.

(somehow the graph only renders if you hit space once)

I made it look nicer.

I've updated your script to the 11.3.

The long space enables and disables the wave line.

1. That is the wave line in the middle?
2. Why the learned NN have wrong result by the 1, 0 input? It shows 0, not expected 1
3. Why you have "nn.func.cos, nn.func.sin", the second one must be the derivative of the first one
4. How works this feature with canvas? I've not used it before.

Thanks!

1. I do not understand what you mean with wave line? or you mean the plotter. it shows the error if it gets consistently to 0 its good.
2. The net has no optimizatios whatsoever to counter vanishing gradients etc. (just restart the program and hope it works the next time)
3. sin actually is the derivate of cos and vice versa (sin' = cos; sin'' = sin)
4. canvas is like the screen you render to but as texture. so you render to an invisible screen, then render the invisible screen
like you tell the program to forward any render operation to a canvas by enabling it. then render and disable rendering to the canvas.
after that you can draw the canvas to the screen or another canvas

3. sin' = cos but cos' = -sin; sin'' = - sin

4. Why here is two canvas? The first one can use the second, but the second one can use the fist one.
Is canvas here to fast simulation? To set the vertical synchronization?

3. oh okay my fault '

4. i think for the fading effect of the plot i used it. the implementation may or may not be optimimal
