讲座内容简介:

The discovery of rough sets by Professor Zdzisław Pawlak from Poland has completed 35 years. The theory has already attracted the attention of many researchers and practitioners, who have contributed essentially to its development, all over the world, including China. The methods, developed based on rough set theory alone or in combination with other approaches, found applications in many areas. In this lecture, we outline some selected past and present research directions on rough sets. In particular, we emphasize the importance of searching strategies for relevant approximation spaces as the basic tools in achieving computational building blocks (granules or patterns) required for approximation of complex vague concepts. This is crucial for many real-life problems.  In solving such problems, information granulation leading to information granules, the basic concept of Granular Computing (GrC), plays an important role. In Data Science, we deal not only with Big Data but we should develop methods for acquiring such Big Data in interaction with complex systems embedded in the physical reality. Recently, in searching for foundations of Data Science, GC was extended to Interactive Granular Computing (IGrC) where computations are performed on complex granules embedded in the physical reality and reasoning about properties of such computations is based on adaptive judgment. Using this computing model, we discuss some challenges of Data Science, e.g., related to knowledge discovery, in particular, to control problems of computations over complex granules or risk management.
