| For the unfamiliar, could someone explain what I'm looking at? The abstract was a little too concrete (heh) for me to follow. |

| If you're familiar with CAs (e.g. Conway's Game of Life), you can think of a NeuralCA as a CA where the update rule is given by a neural network. Here we optimize the neural net weights so that it behaves a certain way (e.g. grow a lizard from a single seed). |

| ▲ | esychology 6 hours ago | parent [-] | | The input to the NN is just the 3x3 neighborhood around a cell.
We can overlap two NNs on the same grid (through interpolation). Checkout https://meshnca.github.io
to see the effect. When the brush is in graft mode, it basically allows you to paint some regions that will follow a different NN rule. | | |

| The original NCA is probably a helpful intro:
