The Geometry of Conditional Independence Tree Models with Hidden Variables

In this paper we investigate the geometry of undirected graphical models of trees when all the variables in the system are binary and some of them are hidden. We obtain a full description of those models which is given by polynomial equations and inequalities and give exact formulas for their parameters in terms of the marginal probability over the observed variables. We also show how correlati...

The Geometry of Independence Tree Models with Hidden Variables

In this paper we investigate the geometry of undirected discrete graphical models of trees when all the variables in the system are binary and the inner nodes are unobserved . We obtain a full geometric description of these models which is given by polynomial equations and inequalities. We also give exact formulas for their parameters in terms of the marginal probability over the observed varia...

Independence in Information Spaces

Three different types of interdependence between pieces of information, or “secrets”, are discussed and compared. Two of them, functional dependence and nondeducibility, have been studied and axiomatized before. This article introduces a third type of interdependence and provides a complete and decidable axiomatization of this new relation.

Third-degree conflicts: information warfare

European Journal of Information Systems (2010) 19, 1–4. doi:10.1057/ejis.2010.2 The concept of the Internet as a potential military battlefield is not particularly new. The Internet itself is rooted to the military notion of a bomb-proof defense network. Similarly, the feasibility of attacking information systems across this network was proven in the 1980s by the Morris Worm. This Internet worm...
