In this paper, we will briefly review the problem of IDS and IPS performance evaluation, demonstrating how flawed current approaches to evaluation are, both in academia and in the industry. We will show all the issues in current testing methodologies, as well as key reasons to distrust claimed performance rates of current IDS systems. We will also show how practical testing architectures can be...

to laymen. They deal with emotional reactions to frustration and failure, to acute illness, to fertility and sterility, to divorce, and to death and suicide. The fourth and seventh of the above, by Dr. Leo Bartemeier and Dr. Jules Masserman respectively, are thought provoking and profound, and Dr. Spiegler's account of reactions to catastrophe helpful to the individual and perhaps to the intern...

We introduce and analyze “multistage situations”, which generalize “multistage games” (which, in turn, generalize “repeated games”). One reason for this generalization is to avoid the perhaps unrealistic constraint inherent to noncooperative games that the set of strategy tuples must be a Cartesian product of the strategy sets of the players. Another reason is that in most economic and social a...

The beliefs of the agents in a multi-agent system have been formally modelled in the last decades using doxastic logics. The possible worlds model and its associated Kripke semantics provide an intuitive semantics for these logics, but they commit us to model agents that are logically omniscient. We propose a way of avoiding this problem, using a new kind of entities called subjective situation...

This paper studies the notion of similarity with reference to situations of situation theory. While the commonsense notion of two situations resembling each other appears to be valuable in our daily life, we show that it is problematic for the same reasons researchers have been pointing out in psychological and philosophical literature. That human beings can u e the notion naturally (without mu...
