Uncertainty and information : foundations of generalized information theory

The principle aim of this book is to provide readers with a comprehensive and in-depth overview of GIT research to create a unified framework of the technology's diverse uncertainty theories. Through the use of examples and exercises, the author discusses probability theory, fuzzy set theory, evidence theory and possibility theory
