The Berlin Big Data Centre (BBDC) develops highly innovative technologies to organize the vast amounts of data and to derive informed decisions from these in order to create economic and social value. This is achieved through the merger of the previously isolated disciplines of data management and machine learning. The technologies of the center reduce the cost of analysis of Big Data, increase the group of people who can perform large scale data analysis and expand the leading position of Germany in this field in science and industry. The focus is on three exemplary economically, scientifically and socially relevant application areas: materials science, medicine, and information marketplaces. Based on worldwide recognized leading-edge research we want to enable automatic optimization, parallelization, and scalable and adaptive processing algorithms. This covers work in the areas of machine learning, linear algebra, statistics, probability theory, computer linguistics and signal processing.
