Most computing programs now have some form of integrative or capstone course in which students undertake a significant project under supervision. There are many different models for such courses and conducting these courses is a complex task. This report is intended to assist instructors of capstone courses, particularly those new to the model of teaching(More)
Given a set of training data, nearest neighbor classification predicts the class value for an unknown tuple X by searching the training set for the k nearest neighbors to X and then classifying X according to the most frequent class among the k neighbors. Each of the k nearest neighbors casts an equal vote for the class of X. In this paper, we propose a new(More)
"One person's noise is another person's signal". Outlier detection is used to clean up datasets and also to discover useful anomalies, such as criminal activities in electronic commerce, computer intrusion attacks, terrorist threats, agricultural pest infestations, etc. Thus, outlier detection is critically important in the information-based society.

In a database system, careful selection, project, and join (SPJ) optimisation methods are needed to achieve good performance. This is an area of much research in the past two decades, yet much remains to be done. Also, researchers have begun to view data mining as being an integral part of query processing, thus the two are intended to be jointly optimised.(More)
BACKGROUND A high prevalence of sickness absence in many countries, at a substantial societal cost, underlines the importance to understand its determining mechanisms. This study focuses on the link between relative deprivation and the probability of sickness absence. METHODS 184,000 men and women in Sweden were followed between 1982 and 2001. The sample(More)
