Contravariance Theory: Strong Alignment for Minimal Solutions to Hard Tasks

arXiv:2607.08561v1 Announce Type: new Abstract: A series of results from the NeuroAI over the past fifteen years have raised core questions both about how to compare Deep Neural Network (DNN) models to the brain, and about how much convergent evolution to expect between artificial networks and real brain networks. Here, we show that for any two minimal DNN solutions to a sufficiently hard task: (i) "weak" alignment of network representations based on affine mappings guarantees "strong" alignment of privileged axes, and (ii) alignment "zippers" up the network hierarchy, causing the emergence of

Why this matters
Why now

The paper builds on fifteen years of NeuroAI research, suggesting a growing maturity in understanding the fundamental principles governing artificial and biological intelligence.

Why it’s important

This research provides a theoretical framework for understanding 'strong alignment' in complex AI systems, offering insights into convergence between artificial networks and real brains, which is critical for future AI development and interpretability.

What changes

The findings suggest that strong alignment emerges predictably for minimal solutions to hard tasks, potentially simplifying the development of more robust and reliable AI while offering new ways to compare biological and artificial neural networks.
