Research in the “Data Science & Business Analytics” theme seeks to exploit the myriad promises conferred by big data. In the past, traditional descriptive analytics could only equip organizations with fundamental operational observations, signaling deviations and raising alarms when necessary. Moving forward, organizations favor predictive analytics that can help forecast and predict potential relationships between variables and outcomes of concern, so that they can better chart their future and achieve their goals. In this way, analytics has proven useful in helping organizations know what they know and what they don’t. But the untamed potential of big data is even greater – as big data analytics promises to enlighten organizations regarding knowledge discovery, or help them understand what they do not even know they don’t know. However, although big data analytics holds much promise, it is no silver bullet. Our researchers are working on overcoming the challenges of big data in manifold ways. These include efforts on providing tangible and novel insights towards specific business problems e.g., in retail, social networks, and healthcare, as well as fundamental big data challenges e.g., entity resolution, missing value imputation, high-dimensional clustering, and models for transfer learning.
