A comparison of three class separability measures

Author: Mthembu, N S ; Greene, J R Date: 2004 Measures of class separability can provide valuable insights into data, and suggest promising classification algorithms and approaches in data mining. We compare three simple class separability measures used in supervised machine learning. ... Read more
A simple method for visualizing labelled and unlabelled data in high-dimensional spaces

Author: Greene, J R Date: 2004 The low-dimensional visualisation of highdimensional data is a valuable way of detecting structure (such as clusters, and the presence of outliers) in the data, and avoiding some of the pitfalls of blind data manipulation. Projection based ... Read more
Investigation into the feasibility of an electro-optic rail surface monitor

Author: Rawstorne, Alexander F Date: 1993 Cracks and surface imperfections in railway track are important when considering its lifetime. This thesis investigates the feasibility of a new electro-optic technique which records surface irregularities on a track. It is more sensitive to ... Read more
The measurement of flow velocity distribution

Author: Dann, Michael Stephen Date: 1981 A method for the improvement of the range and accuracy achieved by the cross-correlation flowmeter is investigated. The principles of the flowmeter operation and fundamental digital signal processing techniques are reviewed. The process of ... Read more
SOFTWIRE : an interactive, computer-based system for enhancing learning in electrical engineering using simulation
