Researchers have developed a new framework called Growing Neural Cellular Automata (GNCA) to understand how complex morphologies emerge from simple local rules in developing neural networks. By tracing the developmental trajectory of trained GNCA models, they observed that the convergence to a final form is often non-monotonic, passing through transient intermediate configurations. The study also found that hidden channels within the network self-organize into modular groups, and cell states diversify within a low-dimensional manifold. Further analysis using community detection on cell states successfully identified discrete cell types and transient communities during early development, indicating that GNCA development involves a reorganization of transient states rather than simple incremental refinement.
