Description
Summary:Information granules are generic building blocks supporting the processing realized in granular computing and facilitating communication with the environment. In this paper, we are concerned with a fundamental problem of encoding-decoding of information granules. The essence of the problem is outlined as follows: given a finite collection of granular data X1, X2,...,XN (sets, fuzzy sets, etc.), construct an optimal codebook composed of information granules A 1, A2, ..., Ac, where typically c
