Abstract: A training apparatus and a training method for providing a sample size expanding model are provided. A normalizing unit receives a training data set with at least one numeric predictor factor and a numeric response factor. An encoding unit trains the training data set in an initial encoding layer and at least one deep encoding layer. A modeling unit extracts a mean vector and a variance vector and inputting the mean vector and the variance vector together into a latent hidden layer for obtaining the sample size expanding model. A decoding unit trains the training data set in at least one deep decoding layer and a last encoding layer. A verifying unit performs a verification of the sample size expanding model according to the outputting data set. A data generating unit generates a plurality of samples via the sample size expanding model.

Abstract: A method for analyzing a process output and a method for creating an equipment parameter model are provided. The method for analyzing the process output includes the following steps: A plurality of process steps are obtained. A processor obtains a step model set including a plurality of first step regression models, each of which represents a relationship between N of the process steps and a process output. The processor calculates a correlation of each of the first step regression models. The processor picks up at least two of the first step regression models to be a plurality of second step regression models whose correlations are ranked at top among the correlations of the first step regression models. The processor updates the step model set by a plurality of third step regression models, each of which represents a relationship between M of the process steps and the process output.
