North Island weka (Gallirallus australis greyi Buller) have declined in numbers and range this century (Marchant and Higgins, 1993). There are now probably less than 2 000 weka in the North Island of New Zealand and the population is scattered (D. King, pers. comm.; Department of Conservation, Gisborne, NZ) and appears to be still declining (A. Bassett, pers. comm.; Department of Conservation, ...

Data mining tools may be computationally demanding, so there is an increasing interest on parallel computing strategies to improve their performance. The popularization of Graphics Processing Units (GPUs) increased the computing power of current desktop computers, but desktop-based data mining tools do not usually take full advantage of these architectures. This paper exploits an approach to im...

The availability of huge amounts of data resulted in great need of data mining technique in order to generate useful knowledge. In the present study we provide detailed information about data mining techniques with more focus on classification techniques as one important supervised learning technique. We also discuss WEKA software as a tool of choice to perform classification analysis for diffe...

The effect of feral pigs and weka on the abundance, composition and biomass of aboveand below-ground macro-invertebrates was assessed every November over 3 years at two sites where pigs and weka, just pigs, and neither species were excluded on Attempt Hill, D'Urville Island. The large carnivorous snail Powelliphanta hochstetteri obscura increased both inside and outside the exclosures, and sign...

UNLABELLED The Weka machine learning workbench provides a general-purpose environment for automatic classification, regression, clustering and feature selection-common data mining problems in bioinformatics research. It contains an extensive collection of machine learning algorithms and data pre-processing methods complemented by graphical user interfaces for data exploration and the experiment...

WEKA is a widely used, open-source machine learning platform. Due to its intuitive interface, it is particularly popular with novice users. However, such users often find it hard to identify the best approach for their particular dataset among the many available. We describe the new version of Auto-WEKA, a system designed to help such users by automatically searching through the joint space of ...
