arXiv:2605.24057v1 Announce Type: new Abstract: Neural networks acquire structured representations at specific moments during training, yet identifying these transitions typically relies on retrospective, label-dependent metrics. We introduce a bifurcation theory of representation dynamics to detect these moments in real time. Analyzing a passive GMM probe attached to the evolving encoder, we show the onset of structure corresponds to a supercritical pitchfork bifurcation driven by the loss Hessian. The system exhibits a theoretically predictable zero-crossing ($\beta_c$) that, compared to the
The paper provides a theoretical framework for understanding how neural networks develop structured representations, a fundamental aspect of AI development and interpretability.
This research offers a method to detect and understand critical AI learning transitions in real-time, moving beyond retrospective analysis and potentially enabling more efficient and controlled AI training.
The ability to predict and characterize concept emergence through bifurcation theory could lead to more robust, understandable, and strategically optimized AI models.
