Improving Convergent Cross Mapping for Causal Discovery with Gaussian Processes

ICASSP 2020accepted

Convergent cross mapping (CCM) is designed for causal discovery between coupled time series for which Granger's method for detecting causality is shown to be unreliable. The theoretical foundation of CCM is based on state space reconstruction, and therefore, for the accuracy of its results, the qual…

Fetal heart rate analysis by hierarchical dirichlet process mixture models

ICASSP 2016accepted

In this paper, we propose to analyze fetal heart rate (FHR) signals by hierarchical Dirichlet process (HDP) mixture models. We investigate whether the clustering results of real-world FHR time series obtained by these models are informative in terms of determining the health status of a fetus. The F…
