Embodiment Construction

[0039] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0040] Such as figure 1 As shown, the model management system 1 provided in this embodiment to deal with multiple business scenarios includes a model conversion module 11, a model storage module 12, a model upload module 13, a model precompilation module 14, a model testing module 15, a model management module 16, Model update module 17 and operation record database 18 .

[0041] Specifically, the model conversion module 11 is used to convert offline model files into model files in a predetermined format, and in this embodiment, the predetermined format is PMML format. Since the representation of offline model files is different due to factors such as modeling language and modeling method, in order to enable unified management, PMML files are introduced to describe various models. PMML files are cross-platform model definitio...

Abstract

The invention discloses a model management system and method for multi-service scenarios. The model management system includes a model conversion module, a model upload module, a model pre-compilation module, a model test module and a model management module; the model conversion module converts offline models to The files are converted into model files in a predetermined format; the model upload module uploads the model files and loads the model files into the cache; the model precompilation module precompiles the uploaded model files; the model test module performs production environment tests on the model files, If the test is successful, upload the model file; if the test fails, delete the model file from the cache; the model management module receives the request from the client, obtains the corresponding model file according to the request, and processes the request by executing the model file. The invention unifies the process from delivery to online of the model, achieves controllable risks, facilitates unified management of the model, and effectively prevents inconsistent model results caused by environmental differences.

Description

technical field [0001] The invention relates to a model management system and method for multi-service scenarios. Background technique [0002] At present, there are the following defects in model management in multi-business scenarios: [0003] 1. The data analysis team will establish various prediction models for various businesses, and the performance of these models varies due to factors such as modeling language and modeling methods, which makes the entire process from delivery to online of the model uncontrollable; [0004] 2. The representation of the model is different, it may be a series of adjusted parameters, or it may be a persistent file, and the model files produced by different programming languages ​​are inconsistent, which makes it inconvenient to manage uniformly; [0005] 3. In the past, the model was tested in an offline test environment before going online, but after going online to the production environment, the model results may be inconsistent due t...
