Using the piecewise monotone property, we give a full description of non-monotonicity height of PM functions with a single fort on compact interval. This method is also available for general PM functions with finitely many forts, as well as those functions defined on the whole real line. Finally, we obtain a sufficient and necessary condition for the finite non-monotonicity height by characteri...

We present and motivate a formal approach and algorithms for semantic matchmaking in an e-commerce framework. The proposed solution exploits nonmonotonic inferences for explanation services in the query-retrieval-refinement loop, and defines some guidelines to compute semantic-based ranking of offers.

Thielscher, M., On prediction in Theorist (Research Note), Artificial Intelligence 60 (1993) 283-292. Theorist is a well-known framework and system for nonmonotonic reasoning which provides mechanisms for dealing with both explanations for observations and skeptical prediction. Its current implementation, developed by David Poole and co-workers, uses an algorithm for prediction which holds for ...

When a physicist writes down equations, or formulates a theory in any other terms, he or she usually means not only that these equations are true for the real world, but also that the model corresponding to the real world is “typical” among all the solutions of these equations. This type of argument is used when physicists conclude that some property is true by showing that it is true for “almo...

This paper presents a simple model to show how distributional concerns can engender social conflict. We have a two period model, where the cost of conflict is endogenous in the sense that parties involved have full control over how much conflict they can create. We find that anticipated future inequality plays a crucial role in determining the level of conflict in the current period. The model ...

The cultural and creative industries have very distinct features. From the supplier’s perspective, inherent uncertainty and lack of predictability combined with high failure rates. On the demand side, consumers are not autonomous but are directly affected by the behaviour of others. Further, an individual’s demand for a product may either rise the more other people buy it (bandwagon effect), fa...

[1] Observed North Atlantic Ocean surface temperatures have changed in a non-monotonic and non-uniform fashion over the last century. Here we assess the relative roles of greenhouses gases, anthropogenic aerosols, natural forcings and internal variability to the North Atlantic surface temperature decadal fluctuations using multi-model climate simulations driven by estimates of observed external...

Chebyshev’s integral inequality, also known as the covariance inequality, is an important problem in economics, finance, and decision making. In this paper we derive some covariance inequalities for monotonic and non-monotonic functions. The results developed in our paper could be useful in many applications in economics, finance, and decision making.

The present paper deals with monotonic and dual monotonic language learning from positive as well as from positive and negative examples. The three notions of monotonicity re ect di erent formalizations of the requirement that the learner has to produce better and better generalizations when fed more and more data on the concept to be learned. The three versions of dual monotonicity describe th...
