Estimating Prediction Intervals for Arti cial
نویسندگان
چکیده
Neural networks can be viewed as nonlinear models, where the weights are parameters to be estimated. In general two parameter estimation methods are used: nonlinear regression, corresponding to the standard backpropagation algorithm, and Bayesian estimation, in which the model parameters are considered as being random variables drawn from a prior distribution, which is updated based on the observed data. These two estimation methods suggest diierent methods of calculating prediction intervals for neural networks. We present some preliminary observations comparing the ability of the two methods to provide accurate prediction intervals.
