Growing a Neural Network in Breadth, Depth, and Time

arXiv:2605.25174v1 Announce Type: cross Abstract: Spatial and temporal resource constraints are critical for both biological and artificial intelligent systems. Here we define differentiable cost terms for breadth, depth, and time within a recurrent convolutional neural network conceived as a finite subset of an infinite lattice. We optimize these costs jointly with task errors via backpropagation. We set different pressures on breadth, depth, and time, which leads to diverse computational graphs emerging organically through training. We find that all three resources can be traded off against

Why this matters
Why now

The continuous push for more efficient and adaptable AI systems, coupled with increasing computational constraints, drives research into optimizing neural network growth and resource allocation.

Why it’s important

This research could lead to more robust and resource-efficient AI models, enabling novel applications in constrained environments and reducing the overall compute footprint of advanced AI.

What changes

The ability to organically grow and optimize neural networks across breadth, depth, and time could significantly alter how AI models are designed, trained, and deployed, moving towards more adaptive and less human-intensive architectural selection.
