Prediction-model-building method, state prediction method and devices thereof

Abstract

A prediction-model-building method includes: generating a plurality of pieces of augmented training data after a piece of training data with a missing item is determined; constituting a training dataset comprising pieces of training data without any missing item and the plurality of pieces of augmented training data; and building a prediction model based on the training dataset by a machine-learning algorithm. Similarly, a state prediction method includes: generating a plurality of pieces of estimation augmented data after a piece of source data with a missing item is determined; inputting the said plurality of pieces of estimation augmented data into a prediction model; and outputting a predicted state based on the output of the prediction model. Devices for performing the above methods are also disclosed.
