In normal situations pigs show a stable diurnal drinking pattern. Based on experimental data a dynamic model is developed for prediction of the drinking behavior of growing pigs. A state space model with cyclic components is proposed for modelling the diurnal drinking pattern, measured as hourly sums. Determination of variance structure by use of discount factors is suggested. Model performance...

| We address pruning and evaluation of Tapped-Delay Neural Networks for the sunspot benchmark series. It is shown that the generalization ability of the networks can be improved by pruning using the Optimal Brain Damage method of Le Cun, Denker and Solla. A stop criterion for the pruning algorithm is formulated using a modiied version of Akaike's Final Prediction Error estimate. With the propos...

Non-stationary Prediction Error Filters (PEF’s) present an effective approach for separating multiples from primaries in the angle domain. The choice of models to be used for estimation of the PEF’s has a substantial impact on the final result, but is not an obvious decision. Muting in the parabolic radon transform (PRT) domain produces an effective multiple model, but the corresponding primary...
