Abstract

The invention discloses a method for optimizing random forest parameters used in machine learning model training. First, the entire ant population is divided into several subpopulations; Independent evolution; Finally, the migration operator is used to exchange information between subpopulations. Compared with the traditional grid search, the Spark-based parallel antlion algorithm can efficiently find a better parameter combination to improve the classification accuracy of the random forest, and under the big data distributed Spark platform, the optimization calculation speed is fast and the acceleration effect is obvious , which can be used as a next-generation parameter optimizer for cloud computing platforms.

Description

technical field [0001] The invention belongs to the field of large-scale machine learning model training, and relates to a method for optimizing random forest parameters for machine learning model training, in particular to a Spark-based parallel antlion algorithm for machine learning model training to optimize random forests parameter method. Background technique [0002] In recent years, with the rapid growth of information data, machine learning models have been widely promoted and applied. However, as the most critical part of model training, model parameter optimization has always been a difficult problem, and it often takes a long time for engineering. The solution process of classical optimization methods will lead to relatively large time complexity or space complexity, and the final parameter optimization level is closely related to the function form of the problem to be solved. As a random search algorithm imitating the behavior of biological groups, swarm intell...
