Abstract

The invention discloses a data processing method and device, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: determining a training data set for training a data processing model, wherein the data processing model is used for carrying out data processing according to a plurality of strategies with priority sequences; and according to the sequence of the priorities of the strategies from high to low and a preset strategy combination mode, sequentially generating a decision tree corresponding to each strategy, and taking the decision tree corresponding to the strategy with the lowest priority as a data processing model. According to the embodiment, data processing can be carried out according to a plurality of strategies with priority sequences, so that the problem of single processing value of a traditional decision tree is solved by an analysis method based on target value disassembly and integration and a loss function corresponding to the analysis method, and data processing is more reasonable and scientific.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data processing method and device. Background technique [0002] Whether it is a marketing scenario or a risk control scenario, as long as it involves the automated processing of a specific business, it usually does not rely on only one model to formulate an automated processing plan, because the model usually only provides a single value measurement, and the automated processing plan usually considers multiple value factors (For example: stability, overdue rate, credit, coverage, etc.), this automatic processing solution for multi-value measurement is what we usually call "strategy". The strategy usually considers the implementation of the decision tree. The traditional decision tree, like other machine learning models, requires the minimum structural risk, that is, the minimum comprehensive experience risk and generalization error. [0003] In the course of realizi...
