Abstract

The invention provides a model adaptive training method and device, equipment, a medium and a program product, and the method comprises the steps: obtaining all operation data of an original model during actual operation, and detecting a first concept drift value of the original model during actual operation according to the operation data; and then, according to the value model and the first concept drift value, distributing each operation data to a tagged data set and / or a non-tagged data set, and when the data size of the tagged data set is greater than or equal to a preset threshold value, utilizing an adaptive training model, and according to the tagged data set and the non-tagged data set, performing adaptive training on the original model to determine a new trained model. The technical problem of how to enable the AI model to carry out adaptive training under the condition that human intervention is as little as possible is solved. The technical effects that the manual annotation amount needed when the developers update the models is reduced, and the performance stability of the models is improved in the mode of integrating the multiple models are achieved.

Description

technical field [0001] The present application relates to the field of computer data processing, in particular to a numerical model adaptive training method, device, equipment, medium and program product. Background technique [0002] At present, for the AI ​​(Artificial Intelligence, artificial intelligence) model, the existing historical data is generally used for training and then goes online for production services to predict new actual operating data. [0003] However, as time goes by, the phenomenon that the sample distribution changes due to environmental changes is unavoidable, and this phenomenon is called concept drift. At this point, the performance of the AI ​​model will gradually degrade. To this end, we need to retrain the AI ​​model regularly using the latest data to continuously update the AI ​​model, and monitor the model performance in real time to ensure the stable performance of the online AI model. [0004] Therefore, the post-performance maintenance o...
