Efficient operation of a dynamic system requires (near) optimal real-time control decisions. Those decisions depend on a set of control parameters that change over time. Very often, the optimal decision can be made only with the knowledge of future values of control parameters. As a consequence,...

Many organizations aspire to adopt agile processes to take advantage of the numerous benefits that it offers to an organization. Those benefits include, but are not limited to, quicker return on investment, better software quality, and higher customer satisfaction. To date however, there is no...

This dissertation investigates algorithmic techniques for temporal process discovery in many domains. Many different formalisms have been proposed for modeling temporal processes such as motifs, dynamic Bayesian networks and partial orders, but the direct inference of such models from data has...

The objective of this research is to show the utility ofroles and personality characteristics to the evaluation andformation of software development teams. The goals of thisresearch include demonstrating empirically that Belbin'steam roles can be used to form and evaluate software...

In recent years studies have been conducted which suggest thattaking an architecture first approach to managing large softwareprojects can reduce a significant amount of the uncertainty presentin project estimates. As the project progresses, more concreteinformation is known about the planned...

Various business problems are of interest to both data mining and marketing academic communities, such as market segmentation, direct marketing, targeted marketing, personalization/customization, cross selling and discovering customer lifetime value. Yet, these two disciplines have very...

When large numbers of alerts are reported by intrusion detection (ID) systems in very fine granularity, it prevents system administrators from handling the alerts effectively. This in turn degrades the usability of an intrusion detection system. Aside from detection, timely responses of...

Modern computing environments involve a multitude of components working in concert to provide services to users. Computer elements, network elements, operating systems, applications, users, etc. must to be constantly managed and controlled to prevent unintended or illegal accesses that could...

Over the last decade there has been growing interest in pool-based active learning techniques, where instead of receiving an i.i.d. sample from a pool of unlabeled data, a learner may take an active role in selecting examples from the pool. Queries to an oracle (a human annotator in most...

The Internet has become the standard infrastructure for all kinds of communications. At the same time, the emergence of cloud computing and web services has significantly strengthened requirements for the Internet to display greater robustness to disruptions and higher flexibility to support...
