    Abstract: Concepts constitute a concise and fundamental manifestation of key features of data. As emerging at the higher level of abstraction than the data themselves, they capture the essence of the data and usually emerge in the form of information granules.


    In this talk, we identify three main ways in which concepts are encountered and characterized: (i) numeric, (ii) symbolic, and (iii) granular. Each of these views come with their advantages and become complementary to some extent.


    The numeric concepts are built by engaging various clustering techniques. The quality of numeric concepts evaluated at the numeric level is described by a reconstruction criterion. The symbolic description of concepts, which is predominant in the realm of Artificial Intelligence (AI) and symbolic computing, can be represented by sequences of labels (integers). In such a way qualitative aspects of data are captured. This facilitates further qualitative analysis of concepts and constructs involving them by reflecting the bird’s-eye view of the data. The granular concepts augment numeric concepts by bringing information granularity into the picture and invoking the principle of justifiable granularity in their construction.


    We elaborate on the general scheme of processing of granular modeling dwelling upon a collection of granular concepts and their role in granular classifiers and mechanisms of transfer learning among others.
