More recentstudies found that deep learning classifiers trained on synthetic data could improve performance.However, to the best of our knowledge, neither of these methods take advantage of historical, system-specific data. Here, we introduce an approach that trains machine learning classifiers on surrogatedata of past transitions. The approach provides early warning signals in empirical and experimentaldata with higher sensitivity and specificity than two widely used generic early warning signals—variance and lag-1 autocorrelation. Since the approach is trained on surrogates of historical data, it isnot bound by the restricting assumption of a local bifurcation like previous methods. This system-specific approach can contribute to improved early warning signals to help humans better prepare foror avoid undesirable critical transitions.motivated by dynamical systems theory have had mixed success on real noisy data.
