In some classification problems, apart from a good model, we might be interested in obtaining succinct explanations for particular classes. Our goal is to provide simpler classification models for these classes without a significant accuracy loss. In this paper, we propose some modifications to the splitting criteria and the pruning heuristics used by standard top-down decision tree induction a...

Many of the supervised learning algorithms only work with spaces of discrete attributes. Some of the methods proposed in the bibliography focus on the discretization towards the generation of decision rules. This work provides a new discretization algorithm called USD (Unparametrized Supervised Discretization), which transforms the infinite space of the values of the continuous attributes in a ...

Object-oriented databases are a relatively new technology that has great potential for a variety of business applications. The primary advantage of the object-oriented database is that it preserves the natural hierarchical structure of the real world, and for certain cases allows more efficient communication between the database application software and the stored data. This thesis examines two...

The concept of using critical decisions as a basis for defining Information needs has been suggested by several authors. This article reports on results of a decision.oriented approach to planning for MIS. A structured group process Is used to generate both critical decisions and Information needs for a manufacturing firm. Results indicate that the decision approach is effective, particularly f...

a culture conducive to information security practice is extremely important for organizations since information has to be critical assets in modern enterprises. thus for understanding and improving the organizational behavior with regard to information security, enterprises may look into organizational culture and examine how it affects the effectiveness of implementing ism. this study aims to ...

the acceptance of the right project which leads to the realization of the set objectives is one of the most important issues in project-oriented companies. therefore, corporate managers prefer to work on those projects which ensures the achievement of goals such as increasing financial profits or being the top brands in their rivals market. the present  research aimed at introducing  a systemat...

This paper integrates the theory of institutional economics and the task-technology fit model in order to theorize about DSS success (defined in terms of DSS use and decision quality). Institutional economics (Veblen 1899/1912, Ayres 1944 and Bush 1986, 1987) posits that human behavior is either instrumental (rational and associated with “getting a living”) or ceremonial and associated with cus...

The general objective of the Argo project is to build a process-centred environment kernel, providing assistance and active guidance to its users. Thanks to an hybrid approach of process modelling, both task-oriented and decision-oriented, it can be customized to support a broad range of collective design activities. The concept of issue is central to the modelling approach, both on the design ...
