Model construction system and method

The invention provides a model construction system and method, and belongs to the technical field of model construction. The system comprises a data acquisition module used for acquiring sample data of at least one data source; a data detection module which is used for detecting sample data of at least one data source based on a preset quality standard corresponding to the data source, and taking the sample data meeting the preset quality standard as target sample data; a feature extraction module which is used for extracting data features of the target sample data; a feature analysis module which is used for selecting a data feature meeting a preset feature index from the data features as a target feature; a feature processing module which is used for determining the distribution characteristics of the target features and carrying out binning processing on the target features based on the distribution characteristics to obtain a plurality of feature boxes; and a model training module which is used for traini
