This paper provides a non-technical introduction to a procedure to …nd Perfect Bayesian equilibria (PBEs) in incomplete information games. Despite the rapidly expanding literature on industrial organization that uses PBE as its main solution concept, most undergraduate and graduate textbooks still present a relatively theoretical introduction to PBEs. This paper o¤ers a systematic …ve-step proc...

We propose a novelty detection method based on association rule learning as a candidate approach for validating online adaptive systems. Support and confidence intervals in association rules are used as a basis for examining a tested example to trace abnormality. Using a simple mutation algorithm for abnormality generation, the method has been evaluated on different data sets. Obtained experime...

Research on Interactive Storytelling has mainly focused on the opposition between a discourse point of view and a character point of view for a story. In this paper, we propose an approach to model Interactive Storytelling using Linear Logic, which is a support for reasoning on both points of view. Then we give an example on an educational game that shows the possibility of validating a scenari...

Scenarios play an important role throughout the information system development process. Scenarios are partial descriptions of system and environment behavior arising in restricted situations. They are instrumental to the following activities: describing and clarifying the relevant properties of the application domain, uncovering system requirements , evaluating design alternatives, and validati...

This paper introduces two ideas, emotional state dependent utility components (ESDUCs), and evolutionary perfect Bayesian equilibrium (EPBE). Using a simple extensive form game, we illustrate the e¢ciency-enhancing role of a powerful ESDUC, the vengeance motive. Incorporating behavioral noise and observational noise leads to a range of (short run) Perfect Bayesian equilibria (PBE) involving bot...

This article presents a study of lemmatisation of flexible multiword expressions in Lithuanian. An approach based on syntactic analysis designed for multiword term lemmatisation was adapted for a broader range of MWEs taken from the Dictionary of Lithuanian Nominal Phrases. In the present analysis, the main lemmatisation errors are identified and some improvements are proposed. It shows that au...

Programming-by-Example approaches allow users to transform data by simply entering the target data. However, current methods do not scale well to complicated examples, where there are many examples or the examples are long. In this paper, we present an approach that exploits the fact that users iteratively provide examples. It reuses the previous subprograms to improve the efficiency in generat...

This paper presents a query-by-example word spotting in handwritten Arabic documents, based on Scale Invariant Feature Transform (SIFT), without using any text word or line segmentation approach, because any errors affect to the subsequent word representation. First the interest points are automatically extracted from the images using SIFT detector, then, we use SIFT descriptor to represent eac...
