Integrating Human and Machine Intelligence in Galaxy Morphology Classification Tasks
Direct linkDirect link
Beck, Melanie Renee – ProQuest LLC, 2018
The large flood of data flowing from observatories presents significant challenges to astronomy and cosmology--challenges that will only be magnified by projects currently under development. Growth in both volume and velocity of astrophysics data is accelerating: whereas the Sloan Digital Sky Survey (SDSS) has produced 60 terabytes of data in the…

Application of a Hidden Bayes Naive Multiclass Classifier in Network Intrusion Detection
Direct linkDirect link
Koc, Levent – ProQuest LLC, 2013
With increasing Internet connectivity and traffic volume, recent intrusion incidents have reemphasized the importance of network intrusion detection systems for combating increasingly sophisticated network attacks. Techniques such as pattern recognition and the data mining of network events are often used by intrusion detection systems to classify…

Mining Learning Preferences in Web-Based Instruction: Holists vs. Serialists
Peer reviewed Peer reviewed
Direct linkDirect link
Clewley, Natalie; Chen, Sherry Y.; Liu, Xiaohui – Educational Technology & Society, 2011
Web-based instruction programs are used by learners with diverse knowledge, skills and needs. These differences determine their preferences for the design of Web-based instruction programs and ultimately influence learners' success in using them. Cognitive style has been found to significantly affect learners' preferences of web-based instruction…

Analyzing User Interaction to Design an Intelligent e-Learning Environment
Peer reviewed Peer reviewed
Direct linkDirect link
Sharma, Richa – International Journal on E-Learning, 2011
Building intelligent course designing systems adaptable to the learners' needs is one of the key goals of research in e-learning. This goal is all the more crucial as gaining knowledge in an e-learning environment depends solely on computer mediated interaction within the learner group and among the learners and instructors. The patterns generated…

Anomaly Detection Techniques for Ad Hoc Networks
Direct linkDirect link
Cai, Chaoli – ProQuest LLC, 2009
Anomaly detection is an important and indispensable aspect of any computer security mechanism. Ad hoc and mobile networks consist of a number of peer mobile nodes that are capable of communicating with each other absent a fixed infrastructure. Arbitrary node movements and lack of centralized control make them vulnerable to a wide variety of…

Models of Integration Given Multiple Sources of Information.
Peer reviewed Peer reviewed
Massaro, Dominic W.; Friedman, Daniel – Psychological Review, 1990
Several models of information integration are developed and analyzed in the context of a prototypical pattern-recognition task. Evaluation, integration, and decision-making processes are specified for each. Simulations and predictions are carried out to provide a measure of identifiability or extent to which they can be distinguished from one…
