arXiv:2606.07385v1 Announce Type: cross Abstract: Detecting transient chaos from scalar observations without governing equations represents a fundamental challenge in nonlinear dynamics. We propose a geometry-guided machine learning framework that unifies predictive trajectory divergence with macroscopic attractor morphology to track abrupt regime shifts. The methodology extracts a local instability scale via out-of-sample k-nearest neighbor forecast errors to establish the ML-FTLE estimator, subsequently mapping this temporal divergence onto a structural closeness matrix derived from a minima
The paper, published in 2026, details advances in machine learning techniques for analyzing complex nonlinear systems, reflecting ongoing efforts to extract actionable insights from chaotic data.
This research provides a more robust method for detecting sudden regime shifts in chaotic systems, which has implications across various fields from climate modeling to financial markets and AI agent behavior.
The ability to unify trajectory divergence with macroscopic attractor morphology offers a more sophisticated tool for predicting and understanding instability in dynamic systems, moving beyond simpler statistical methods.

Improved detection of critical transitions in complex systems becomes possible with geometry-guided ML-FTLE.
Enhanced predictive capabilities could lead to better early warning systems for ecological collapses, market crashes, or AI system instabilities.
