Abstract : In this Work, an artificial neural network model is introduced that combines the prediction from single neural network predictors according to an adaptive and heuristic credit assignment algorithm based on the theory of conditional probability and Bayesâ€™ rule. Two single predictors are applied and combined linearly into a Bayesian combined neural network model. The credit value for each predictor in the combined model is calculated according to the proposed credit assignment algorithm and largely depends on the accumulative prediction performance of these predictors during the previous prediction intervals. Three indices, i.e., the mean absolute percentage error (MAPE), the variance of absolute percentage error (VAPE), and the probability of percentage error (PPE), are employed to compare the forecasting performance. It is found that most of the time, the combined model outperforms the singular predictors.
