Nowadays, the volume of big data is growing enormously, challenging scientists to provide new ways of organising and analyse it, in order to be able to extract hidden knowledge in the data, and build new automated decision and intelligent reasoning systems.

Solutions to these challenges require expertise from multidisciplinary areas, including statistics, optimization, and computer science, for the efficient processing of large volumes of data, aiming to support decision making including, classification tasks, forecasting, optimization, and visualization.

The Thematic Line Data Science results from an effort to promote interdisciplinary research between NOVA Math and other R&D units and is taking its first steps towards what we expect to be an area of great social impact.
