Predicting Product Review Helpfulness Using Machine Learning And Specialized Classification Models, Scott Bolter Apr 2013

Predicting Product Review Helpfulness Using Machine Learning And Specialized Classification Models, Scott Bolter

Master's Projects

In this paper we focus on automatically classifying product reviews as either helpful or unhelpful using machine learning techniques, namely, SVM classifiers. Using LIBSVM and a set of Amazon product reviews from 25 product categories, we train models for each category to determine if a review will be helpful or unhelpful. Previous work has focused on training one classifier for all reviews in the data set, but we hypothesize that a distinct model for each of the 25 product types available in the review dataset will improve the accuracy of classification. ! Furthermore, we develop a framework to inform authors …

Application Of Secretary Algorithm To Dynamic Load Balancing In User-Space On Multicore Systems, Kyoung-Hwan Yun Apr 2013

Application Of Secretary Algorithm To Dynamic Load Balancing In User-Space On Multicore Systems, Kyoung-Hwan Yun

Master's Projects

In recent years, multicore processors have been so prevalent in many types of
systems and are now widely used even in commodities for a wide range of applications.
Although multicore processors are clearly a popular hardware solution to problems that
were not possible with traditional single-core processors, taking advantage of them are
inevitably met by software challenges. As Amdahl’s law puts it, the performance gain is
limited by the percentage of the software that cannot be run in parallel on multiple cores.
Even when an application is “embarrassingly” parallelized by a careful design of
algorithm and implementation, load balancing of …

User Profiling In Gui Based Windows Systems For Intrusion Detection, Arshi Agrawal Apr 2013

User Profiling In Gui Based Windows Systems For Intrusion Detection, Arshi Agrawal

Master's Projects

Intrusion detection is the process of identifying any unauthorized access to a sys- tem. This process inspects user behavior to identify any possible attack or intrusion. There exists two type of intrusion detection systems (IDSs): signature-based IDS and anomaly-based IDS. This project concentrates on anomaly-based intrusion detection technique. This technique is based on the deviation of intruder’s actions from the authenticated user’s actions. Much previous research has focused on the deviation of command line input in UNIX systems. However, these techniques fail to detect attacks on modern GUI- based systems, where typical user activities include mouse movements and keystrokes. Our …
