a communication net is usually represented by a linear graph g whose branches represent channels for information flow and whose vertices represent sources, sinks and switching centers. the purpose of this paper is to show that for modeling digital communication nets, conventional use of the concepts of capacity and terminal capacity is inadequate . we will present an alternative to max-flow min...

Large data sets often require performing distributed statistical estimation, with a full data set split across multiple machines and limited communication between machines. To study such scenarios, we define and study some refinements of the classical minimax risk that apply to distributed settings, comparing to the performance of estimators with access to the entire data. Lower bounds on these...

Abstract This paper studies the human development performance in visual communication of multimodal channels within artificial intelligence environment. Starting from environmental changes cognition, main characteristics dissemination information context are analyzed, and transformation passive to active cognitive activities is discussed. In process understanding diversified information, contra...
