The rapid growth of data starts to inflict a major impact in many fields such as computational mathematics, optimization, statistics, computer science, etc. Big data analysis is a new and exciting direction which brings vast opportunities and challenges at the same time. Although each field has its own focus in big data analysis, there are also deep and extensive connections among them. The aim of this workshop is to bring together leading researchers in computational mathematics, optimization, statistics, machine learning, and to promote international collaborations.
