In this paper, we build on previous work on Belief Revision operators based on the use of logic programming with Answer Set semantics as a representation language. We present a set of postulates for Answer Set Revision with respect to…

Ceramics are the most common archaeological material used by the historians to draw chronological and cultural characterizations. Among these, porcelains and celadons are recognized as good historical relics. Moreover, the different facets of science, technology and culture are also imprinted…

There are many situations in which a very detailed low-level description encodes, through a hierarchical organization, a recognizable higher-order pattern. The macro-molecular structural conformations of proteins exhibit higher order regularities whose recognition is complicated by many factors. ARIADNE searches for…

Behavior analysis originated from the tradition of the biological sciences, that favor the replication of data analyzing directly the behavior of individual subjects. Other areas of psychology that originated from the social sciences, favor the replication of data analyzing statistically…

This paper presents a novel algorithm for learning in a class of stochastic Markov decision processes (MDPs) with continuous state and action spaces that trades speed for accuracy. A transform of the stochastic MDP into a deterministic one is presented…
