Deep LPPLS: Forecasting of temporal critical points in natural, engineering and financial systems
Joshua Nielsen, Didier Sornette, Maziar Raissi
The Log-Periodic Power Law Singularity (LPPLS) model offers a general framework for capturing dynamics and predicting transition points in diverse natural and social systems. In th…
