Multivariate Time Series Information Bottleneck
Entropy, 2023 Time series (TS) and multiple time series (MTS) predictions have historically paved the way for distinct families of deep learning models. The temporal dimension, distinguished by its evolutionary sequential aspect, is usually modeled by decomposition ...

Forecasting time series with multivariate copulas [PDF]
Dependence Modeling, 2015 Abstract In this paper we present a forecasting method for time series using copula-based models for multivariate time series. We study how the performance of the predictions evolves when changing the strength of the different possible dependencies, as well as the structure of the dependence.
