ARCHIE Project description:
Potential output of the project:

Network training, pruning and set assembly of an adaptive Baysian model selection process that is being implemented to make robust storm surge forecast predictions for the Firth of Clyde. The 3, 6 and 12 hour forecast prediction is made by training sets of neural networks on a number of pressure, wind stress and surge variables and then exploiting the variability of the training process across sets of artificial neural networks with randomized starting weights to quantify the uncertainty of the prediction. The model selection method uses Bayes theory (assuming uniform priors) to compute the posterior probability associated with each network in the set, in the form of a continuous distribution over the output domain. The robust prediction with confidence bounds are obtained by assigning weights to the individual network output according to the previously calculated posterior probabilities. Inefficient network architectures are pruned using optimal brain surgery method by assessing the second order derivative of the error function and removing the unimportant weights from the network architecture. The aim of simplifying the network complexity is to improve generalisation and increase the speed of further training.
