研究人员开发了一个名为FlowMSM的新框架，以应对识别非平稳时间序列数据中潜在状态和因果结构的挑战。该框架旨在处理复杂的动态，包括非线性和非高斯行为，以及变量之间的瞬时效应。该方法为潜在状态和依赖于状态的因果结构建立了理论可识别性，并在合成基准和金融经济学数据集上证明了其有效性。 AI
影响 提供了一种分析复杂时间序列数据的新方法，有可能改进金融、气候科学和医疗保健领域的应用。

arXiv:2606.02231v1 Announce Type: new Abstract: Temporal systems often exhibit non-stationary behaviour, such as seasonal climate variation or glucose fluctuations in patients with type-1 diabetes. One way to model non-stationarity is through discrete latent regimes, i.e., statio…
Temporal systems often exhibit non-stationary behaviour, such as seasonal climate variation or glucose fluctuations in patients with type-1 diabetes. One way to model non-stationarity is through discrete latent regimes, i.e., stationary segments of time. Such systems induce a Mar…
