Abstract

The invention discloses a mobile terminal replacement prediction method, device and equipment and a readable storage medium, and the method comprises the steps: obtaining business data, constructing RandomForst and XGBOOST models, converting leaf node positions of a sample in the models into one-hot coding features, and generating a first feature; performing feature combination on the first features to generate second features, and combining the first features and the second features; selecting the merged features by adopting an integrated filtering method, and removing the features with poorcharacterization capability; constructing a sample weight function, and optimizing a model loss function; and constructing a logistic regression random forest based on a bagging framework, and performing mobile terminal replacement prediction through a model. According to the technical scheme, the method has the advantages of being high in representation capacity, low in cost, accurate in prediction and high in robustness, operators can conveniently and accurately market mobile phones to users, and high commercial value is achieved.
