Developing a Course Recommender by Combining Clustering and Fuzzy Association Rules
Each semester, students go through the process of selecting appropriate courses. It is difficult to find information about each course and ultimately make decisions. The objective of this paper is to design a course recommender model which takes student characteristics into account to recommend appropriate courses. The model uses clustering to identify students with similar interests and skills...
متن کاملA Methodology for Unified Assessment of Physical and Geographical Dependencies of Wide Area Measurement Systems in Smart Grids
Wide Area Measurement Systems (WAMS) enable real time monitoring and control of smart grids by combining digital measurement devices, communication and control systems. As WAMS consist of various infrastructures, they imply complex dependencies among their underlying systems and components of different types, such as cyber, physical and geographical dependencies. Although several works exist in...
متن کاملWelfarist evaluations of decision rules under interstate utility dependencies
We provide welfarist evaluations of decision rules for federations of states and consider models, under which the interests of people from different states are stochastically dependent. We concentrate on two welfarist standards, viz. that the expected average utility for a person in the federation be maximized or that the expected utilities for the different people be equal. We discuss an analy...
متن کاملInduction of LDA Oblique Decision Rules
This paper presents a new algorithm of decision rules with oblique conditions induction. It bases on the Fisher’s Linear Discriminant Analysis as a tool of finding an initial classes separation. This technique has a good ability of oblique dependencies generalisation what reduces the number of decision rules and their complexities. Keywords—classification, machine learning, Linear Discriminant ...
متن کاملReasoning about Data - A Rough Set Perspective
[ Abstract.] The paper contains some considerations concerning the relationship between decision rules and inference rules from the rough set theory perspective. It is shown that decision rules can be interpreted as a generalization of the modus ponens inference rule, however there is an essential difference between these two concepts. Decision rules in the rough set approach are used to descri...
