Abstract

The invention provides a method and device for constructing a prediction model, computing equipment and a storage medium, and belongs to the technical field of artificial intelligence. The method comprises the steps of obtaining a model search space corresponding to a target prediction scene according to a target data set of the target prediction scene and / or scene information of the target prediction scene, wherein the model search space comprises a model and a hyper-parameter; performing model training according to the target data set and the model and hyper-parameters included in the model search space to obtain a trained prediction model; and obtaining a prediction model corresponding to the target prediction scene according to an evaluation result of the trained prediction model. By adopting the invention, the efficiency of constructing the prediction model can be improved.

Description

Technical field [0001] The present application relates to artificial intelligence technology, and particularly relates to a method of constructing a prediction model, means for calculating device and a storage medium. Background technique [0002] With the development of computing technology, commonly used predictive models to predict some phenomena occur in the future, so it is necessary to build predictive models. [0003] The related art, when building predictive models, model search space includes all current machine learning models collected randomly select a machine learning model from the model search space, based on the sample data, the machine learning model parameter optimization and super training, and finally to complete the training of the prediction model, performance evaluation, and determine whether all the machine learning model model search space are tried. If you do not have to try too, then re-model search space, choose a machine learning model for training ma...
