Hierachical Neural Cellular Automata
Ritu Pande, Daniele Grattarola
There are two experiments performed to show the capabilities of H-NCA, namely, Cell Differentiation and Metamorphosis . Cell Differentiation involves morphing of the patterns generated by the child-NCA to the patterns required by the parent-NCA while Metamorphosis involves descruction of the patterns generated by the child-NCA and the morphology required by the parent-NCA takes over.
To reproduce the results of the paper, open hnca.ipynb from the repository in Google Colab and load the model weights. Then evolve the model using those weights. You can also train the models afresh following the instructions in the notebook.
