Replacing operation method and device after model update and business server

Abstract

The invention discloses a replacing operation method and device after model update and a business server. The method comprise that comprehensive properties of different updated models are compared; the updated model with the optimal comprehensive property is determined to be a candidate model; performance of the candidate model is compared with that of a present online operation model in a specific risk threshold, the performance of the candidate model or the present online operation model in the specific risk threshold is determined according to a standard score corresponding the a score output by a specific online event set as well as an auditing result for the specific online event set obtained according to the standard score and the specific risk threshold, and the specific risk threshold is determined according to a preset model strategy; if the comparison result shows that the performance of the candidate model is higher than that of the present online operation model, the candidate model is disposed as the online operation model.

Description

technical field [0001] The embodiments of this description relate to the technical field of data processing, and in particular to a method, device, and service server for replacing and running a model after it is updated. Background technique [0002] The essence of intelligent or automatic processing is the process in which the computer obtains the corresponding output information after calculation according to the given input information. The model is a kind of information used to describe the above-mentioned input-output relationship. A simple model can be based on Artificial rules are established. In the data age, data modeling based on big data and machine learning technology has become the mainstream. At present, in various application fields, big data modeling has been widely used to realize various intelligent processing functions. With the automatic update of the model and the replacement of the old and new models, it is also necessary to re-deploy the model policy...

Problems solved by technology

However, since the independent model is trained based on certain historical data samples, as time goes by, there may be various factors that lead to the decline of the applicability of the independent model, so it is necessary to update the independent model in a timely manner. Correspondingly, for the integration The model also needs to be updated in a timely manner. For example, a refit update is performed on each integrated model (including the currently officially running integrated model) every week. After each integrated model is updated, it is necessary to re-select an integrated model with the best performance. Replace the currently officially running integrated model and redeploy the model strategy at the same time. However, at present, more manual intervention is still required in the evaluation and selection of the model and the deployment of the model strategy in the model replacement operation stage, resulting in a longer time-consuming model replacement operation cycle. , which results in the updated integration model not being able to function in a timely manner
