Null-model validation of MLP input contribution analysis in ecology
(IEEE Computer Society, 2006-12)
A method is presented for applying a null-model analysis to the verification of the significance of the input neurons of Multi-Layer Perceptrons (MLP). This method was applied to a problem from ecology, namely the establishment ...
Nominal-scale evolving connectionist systems
(IEEE, 2006-07)
A method is presented for extending the evolving connectionist system (ECoS) algorithm that allows it to explicitly represent and learn nominal-scale data without the need for an orthogonal or binary encoding scheme. ...
Food or sex: which would you choose? Pollinator-prey conflict and reproductive assurance in New Zealand Drosera
(Lincoln University, 2009)
This is the first study to test the possibility that autonomous selfing in carnivorous plants functions as a mechanism to reduce the pollinator-prey conflict by reducing pollen-limitation. Carnivorous plants can rely on ...
Molecular systematics and colour variation of Carpophilus species (Coleoptera: Nitidulidae) of the South Pacific
(Lincoln University, 2009)
The sap beetle genus Carpophilus Stephens (Coleoptera: Nitidulidae) is a large genus consisting of over 200 species and are found worldwide. Several species are important pests of crops and stored products, and are frequently ...
Using MLP to determine abiotic factors influencing the establishment of insect pest species
(IEEE, 2006-07)
The use of multi-layer perceptrons (MLP) to determine the significance of climatic variables to the establishment of insect pest species is described. Results show that the MLP are able to learn to accurately predict the ...
Valuation of impacts of incursions on biodiversity: A review of the literature
(Nimmo-Bell & Company Ltd., 2006-06-30)
This report provides an overview of the economic literature on invasive species with
focus aimed at economic valuation. The report opens with an overview of economics
concepts related to invasive species. Costs of invasive ...
Biochemistry and genetics of carotenoid composition in potato tubers
(Lincoln University, 2009)
Potato cultivars exhibit a wide variation in skin and flesh colour due to the presence of pigments. This study established that potato cultivars differ greatly with respect to types and concentrations of carotenoids in ...
Objective functions for comparing simulations with insect trap catch data
(Modelling and Simulation Society of Australia and New Zealand and International Association for Mathematics and Computers in Simulation, 2009-07)
Targeted surveillance of high risk invasion sites using insect traps is becoming an important tool in border biosecurity, aiding in early detection and subsequent monitoring of eradication attempts. The mark-release-recapture ...
Phaeomoniella chlamydospora: potential inoculum sources in the grapevine propagation process
(Lincoln University, 2004)
Phaeomoniella chlamydospora is a recently described fungal pathogen that infects grapevines causing Petri disease, which is observed externally as a general decline. The objective of this research programme was to identify ...
Developing an optimal method for producing a tearless onion
(Lincoln University, 2008)
People experience the irritating tearing and burning sensation of lachrymatory factor (LF, propanthial S-oxide) when cutting or chopping onion bulbs. LF is produced by lachrymatory factor synthase (LFS) specifically from ...
