Abstract: A mining method for sample grouping is provided. The method includes the following steps. A field dataset including multiple samples is obtained, and each sample corresponds to an actual labeled result. The samples are respectively input to an existing model, so as to obtain the estimated results. An outlier sample set in the field dataset is removed based on a difference distribution of the estimated results and the actual labeled results, and the samples that remain in the field dataset form a remaining sample set. The remaining sample set is grouped into a hard sample set and an easy sample set based on the estimated results of the remaining sample set.
