چکیده
Time series analysis has proven to be a powerful method characterize several phenomena in biology, neuroscience and economics, understand some of their underlying dynamical features. Several methods have been proposed for the multivariate time series, yet most them neglect effect non-pairwise interactions on emerging dynamics. Here, we propose framework temporal evolution higher-order dependencies within series. Using network topology, show that our robustly differentiates various spatiotemporal regimes coupled chaotic maps. This includes phases types synchronization. Hence, using co-fluctuation patterns simulated processes as guide, highlight quantify signatures data from brain functional activity, financial markets epidemics. Overall, approach sheds light organization allowing better characterization group inherent real-world data. Most analyses rely pairwise statistics. A study combining theory topological now shows how dynamics signals at all orders

Modelling Multivariate Time Series
Multivariate time series (MTS) data are widely available in di erent elds including medicine, nance, science and engineering. Modelling MTS data e ectively is important for many decision-making activities. In this paper, we will describe some of our e orts in modelling these data for numerous tasks such as outlier analysis, forecasting and explanation. Through the analysis of various kinds of M...
متن کاملArtificial Higher Order Neural Networks in Time Series Prediction
Real world problems are described by nonlinear and chaotic processes, which makes them hard to model and predict. This chapter first compares the neural network (NN) and the artificial higher order neural network (HONN) and then presents commonly known neural network architectures and a number of HONN architectures. The time series prediction problem is formulated as a system identification pro...
متن کاملHigher order neural networks for financial time series prediction
Generalized correlation higher order neural network designs are developed. Their performance is compared with that of first order networks, conventional higher order neural network designs, and higher order linear regression networks for financial time series prediction. The correlation higher order neural network design is shown to give the highest accuracy for prediction of stock market share...
متن کاملModelling of Multivariate Time Series
We introduce graphical time series models for the analysis of dynamic relationships among variables in multivariate time series. The modelling approach is based on the notion of strong Granger causality and can be applied to time series with non-linear dependencies. The models are derived from ordinary time series models by imposing constraints that are encoded by mixed graphs. In these graphs ...
