Extreme data characteristics (volume, heterogeneity, distribution etc.) challenge the state-of-the-art data-driven analytics and decision-making approaches in many critical domains such as crisis management public safety, cyber-security etc. ExtremeXP will handle the complexity of matching extreme needs with complex analytics processes by placing the end user at the centre of complex analytics processes. Its main goal is to create a next generation decision support system that integrates novel research results from the domains of data integration, machine learning, visual analytics, explainable AI, decentralised trust, knowledge engineering, and model-driven engineering into a common framework. Follow ExtremeXP on Twitter and LinkedIn.
