Abstract
With the increasing use of advanced technology, the amount of data in our world has been exploding. Big data analytics can examine large data sets and uncover hidden patterns. On the other hand, poor quality of big data results in some inaccurate insights or compliance failures that give rise to partially complete information systems. In order to obtain complete information systems, we use Rough Set Theory (RST), which was introduced by Pawlak in 1982 as a way to deal with data analysis based on approximation methods in information systems. The theory has many applications in a number of different areas, such as engineering, environment, banking, medicine, bioinformatics, pattern recognition, data mining, machine learning and others. RST is intrinsically a study of equivalence relations on the universe (a set of object). In fact, rough sets can be used to represent ambiguity, vagueness and general uncertainty. Given some relations between objects in the set, we can construct lower and upper approximations of the objects. We intend to use some advanced computing methods to determine lower and upper approximations and find several properties of the characteristics of objects within RST, as well as to extend RST to generalized RST. This line of research has to do with some developments in big data analytics. Traditional algorithm cannot satisfy the needs of big data computing. In this presentation, we will show some advanced computing methods that can solve our problems effectively. We will also present several examples to illustrate the concepts introduced in this presentation
