A comparative study of three neural networks that use soft competition
Butchart, K. (University of Hertfordshire, 1994)This report provides a comparative study of three proposed self-organising neural network models that use forms of soft competition. The use of soft competition helps the neural networks to avoid poor local minima and so ... -
Hierarchical Classification with a Competitive Evolutionary Neural Tree
Adams, R.G.; Butchart, K.; Davey, N. (1999)A new, dynamic, tree structured network, the Competitive Evolutionary Neural Tree (CENT) is introduced. The network is able to provide a hierarchical classification of unlabelled data sets. The main advantage that the CENT ... -
An investigation into the performance and representation of a stochastic evolutionary neural tree
Butchart, K.; Davey, N.; Adams, R.G. (Springer Nature, 1997)The Stochastic Competitive Evolutionary Neural Tree (SCENT) is a new unsupervised neural net that dynamically evolves a representational structure in response to its training data. Uniquely SCENT requires no initial parameter ... -
Investigation of self-organising dynamic neural tree networks
Butchart, K. (University of Hertfordshire, 1995)Self Organising Dynamic Neural Tree Networks (DNTNs) provide hierarchical clustering that is potentially applicable to large data sets. Two DNTN models have been produced by Racz and Klotz and Li et al. Four DNTN variants ...
