Hi, everyone, I would like to employ the ANN for the probability analysis. In the process, the ANN can support deterministic model when the high accuracy can be obtained. However, when less accuracy, I just view the ANN as the stochatic model. Consequently, I need to get the confident interval of prediction interval of ANN model. Then I can get the sampling from those intervals for the following probability analysis. I know how to calculate the intervals when the input data number is larger than that of parameters trained in the ANN. But how can I get those intervals when the input data number is smaller ( N-p
