New FlowMSM framework identifies regimes in non-stationary time series

Researchers have developed a new framework called FlowMSM to address the challenge of identifying latent regimes in temporal systems with non-stationary behavior. This framework establishes the identifiability of both latent regimes and regime-dependent causal structures, even with instantaneous effects and nonlinear dynamics. Experiments on synthetic and financial datasets show FlowMSM's effectiveness in detecting these regimes and discovering causal structures from non-stationary time series. AI
