KernTune: Self-tuning Linux Kernel Performance Using Support Vector Machines
(University of the Western Cape, 2006)
Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ...
Self-tuning Linux Kernel Performance Using Support Vector Machines
(University of the Western Cape, 2006)
In this chapter, we provide the motivation and background behind the automatic
optimisation of an operating system. We begin with a discussion of some of the
difficulties of automatic operating system optimisation and ...
Credit Card Transactions Fraud Detection, and Machine Learning: Modelling Time with LSTM Recurrent Neural Networks
(University of the Western Cape, 2007)
In recent years, topics such as fraud detection and fraud prevention have received a lot of attention on the research front, in particular from plastic card issuers. The reason for this increase in research activity can ...
Automatic real-time facial expression recognition for signed language translation
(University of the Western Cape, 2006)
We investigated two computer vision techniques designed to increase both the recognition accuracy and computational efficiency of automatic facial expression recognition. In particular, we compared a local segmentation of ...
Towards a chereme based dynamic South African sign language gesture recognition system
(University of the Western Cape, 2007)
Hand gestures are a natural and intuitive way of human to human communication.
Motivated by the achievements made towards automatic speech recognition, and by the
ease with which people sign, many researchers started ...
Long short-term memory recurrent neural networks for signature verification
(UWC, 2003)
Handwritten signature verification is defined as the classification process that strives to learn the manner in which an individual makes use of the muscular memory of their hands, fingers, and wrist to reproduce a signature. ...
Application of Several Time Series Methods to Three Important Financial Time Series
(University of the Western Cape, 2007)
This study is concerned with three different financial time series over an eight year period, namely: the government repurchase rate, the Rand-Dollar exchange rate and the Allshare Index. The aim is to better understand ...
Foreign Exchange Option Valuation under Stochastic Volatility
(University of the Western Cape, 2009)
The case of pricing options under constant volatility has been common practise for decades. Yet market data proves that the volatility is a stochastic phenomenon, this is evident in longer duration instruments in which the ...
Semi-synchronous video for deaf telephony with an adapted synchronous codec
(University of the Western Cape, 2009)
As Information and Communication Technology (ICT) matures, communication services
must be improved to meet the needs of all types of users. For some uses, current Video over
Internet Protocol (IP) brings unsatisfactory ...
Chereme- Based Recognition of Isolated, Dynamic Gestures from South African Sign Language with Hidden Markov Models
(University of the Western Cape, 2006)
Much work has been done in building systems that can recognise gestures, e.g. as a component of sign language recognition systems. These systems typically use whole gestures as the smallest unit for recognition. Although ...
