DETERMINING COMPUTER-EXECUTED ENSEMBLE MODEL

Abstract:

Implementations of the present specification provide a method for determining a computer-executed ensemble model. The method includes: obtaining a current ensemble model and a plurality of untrained candidate submodels; integrating each of the plurality of candidate submodels into the current ensemble model to obtain a plurality of first candidate ensemble models; training at least the plurality of first candidate ensemble models to obtain a plurality of second candidate ensemble models after this training; performing performance evaluation on each of the plurality of second candidate ensemble models to obtain corresponding performance evaluation results; determining, based on the performance evaluation results, an optimal candidate ensemble model with optimal performance from the plurality of second candidate ensemble models; and updating the current ensemble model with the optimal candidate ensemble model if the performance of the optimal candidate ensemble model satisfies a predetermined condition.
