Abstract

Big Data is characterized by volume, velocity, variety, and veracity of the data used, as well as the value provided after an appropriate data analysis. In a context of time series, Big Data implies analysing a large number of time series jointly (high dimension) in fine granularities (high frequency), and can even use data from external sources, such as social networks, newspapers and specialized forums. This has generated a growing demand for appropriate models and methodologies for modelling and forecasting time series in different fields, such as economics, finance, energy, retail, urban traffic and cybersecurity. Therefore, it is necessary the constant development/extension of models and methodologies that allow to properly capture the dynamics of this data, object of this research project. (AU)
