Abstract In the development of neural networks, many realizations are performed to decide which solution provides the smallest prediction error. Due to the inevitable random errors associated with the data and the randomness related to the network (e.g.,?initialization of the weight and initial conditions linked to the learning procedure), there is usually not an optimal solution. However, we can advantage of the idea of making several realizations based on resampling methods. Resampling methods are often used to replace theoretical assumptions by repeatedly resampling the original data and making inferences from the resampling. Resampling methods provide us the opportunity to do the interval prediction instead of only one point prediction. Following this idea, we introduce three resampling methods in neural networks, namely Delete-d Jackknife Trials, Delete-1 Jackknife Trials, and Hold-Out Trials. They are discussed and applied to a real coordinate transformation problem. Although the Delete-1 Jackknife Trials offer better results, the choice of resampling method will depend on the dimension of the problem at hand.
