Abstract

The invention discloses a management method and device for models in a data warehouse, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps: determining one or more first feature attributes of a plurality of models in the data warehouse; calculating an information gain of the first feature attribute; taking the first characteristic attribute of which the information gain is greater than a threshold value as a second characteristic attribute; respectively calculating management priority values of the plurality of models according to the one or more second feature attribute values of the plurality of models; and determining a management strategy of the model according to the management priority value of the model. According to the embodiment, the accuracy of model grading in the data warehouse is improved, and then accurate management of the model is achieved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for managing models in a data warehouse. Background technique [0002] As the scale of the data warehouse becomes larger and larger, there are often thousands of models behind the data warehouse. How to reasonably classify a large number of models to identify the importance of different models is crucial to the efficient management of models. very important. [0003] At present, models are usually classified based on the subjective judgment of the decision maker on each model. Specifically, the decision maker identifies different levels of labels for the model according to the degree of understanding of the model, so as to use different labels to identify the importance of the model. [0004] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Existing technologies m...
