Data processing and data prediction method

The invention provides a data processing method and a data prediction method. The method comprises the steps of obtaining a first sample data set; the first sample data set comprises a plurality of groups of first sample data. And performing data prediction on the first sample data by using a plurality of preset prediction algorithms to obtain a plurality of data prediction results of the first sample data corresponding to the plurality of prediction algorithms. Respectively calculating performance indexes based on the plurality of data prediction results to obtain a plurality of performance indexes corresponding to the plurality of prediction algorithms; the performance index is used for describing the accuracy degree of data prediction of the corresponding prediction algorithm for the first sample data. And generating a sample label based on the plurality of performance indexes, and adding the sample label to the first sample data. The first sample data added with the sample label is used as a training samp
