The Edge of Chaos: Neural Networks Find Stability in Heavy Tails
![The system’s stability, characterized by the curvature of the Lyapunov potential [latex]1-\mathcal{L}\_{\<i>}[/latex] against the stationary population rate [latex]m\_{\</i>}\[/latex], demonstrates a robust stable regime across a range of activities, though nearing criticality ([latex]m\_{\<i>}\to 0[/latex]) induces a diminished curvature, while an observed “divisive brake” - manifested as inverse scaling of closed-loop susceptibility [latex]d\sigma\_{\</i>}/dh[/latex] with activity - suggests automatic gain control, all supported by analysis using biphasic kernels [latex]G(t)=h\_{\tau\_{1}}(t)-bh\_{\tau\_{2}}(t)[/latex] where [latex]h\_{\tau}(t)=\tau^{-1}e^{-t/\tau}\Theta(t)[/latex].](https://arxiv.org/html/2603.18478v1/sand.png)
