Abstract

The invention relates to a data processing method and device and a computer readable storage medium, and relates to the technical field of computers. The method comprises the steps of determining a to-be-trained machine learning model and a corresponding first hyper-parameter search space according to-be-processed data; sampling candidate hyper-parameters in the first hyper-parameter search space;training a to-be-trained machine learning model by utilizing the first training data set according to the candidate hyper-parameters; re-sampling the candidate hyper-parameters, and repeating the training process according to the re-sampled candidate hyper-parameters until the trained to-be-trained machine learning model meets an iterative stop condition, so as to obtain a trained machine learning model; and processing the to-be-processed data by utilizing the trained machine learning model and the corresponding candidate hyper-parameters.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a data processing method, a data processing device and a computer-readable storage medium. Background technique [0002] Due to the continuous success of the application of machine learning technology in many aspects such as finance, advertising, recommendation system and user behavior analysis, more and more enterprises expect to use machine learning technology to improve the efficiency and quality of business operations. [0003] However, building a machine learning model is a complex and time-consuming process that requires trying different algorithms. Moreover, each algorithm has multiple hyperparameters that need to be set reasonably according to specific data and task goals. [0004] Among related technologies, model selection and hyperparameter tuning based on expert knowledge are mainly used. That is, based on the exploratory analysis of data and the expe...
