In the Growing CA model, “alive” cells are cells which update their state and dead cells are “frozen” and do not undergo updates. Given 19 mutable cell state channels (nine general purpose state channels for communication and ten output state channels for digit classification) and an immutable pixel channel, each cell perceives 19 + 1 state channels and only outputs state updates for the 19 mutable state channels. Starting from a certain digit and after some time evolution, we sample a new digit, erase all cell states that are not present in both digits and bring alive the cells that were not present in the original digit but are present in the new digit.
