Abstract

The present disclosure relates to a method, device, storage medium, and electronic equipment for establishing a feature processing flow. The method includes: obtaining a first hyperparameter set and a second hyperparameter set according to the number of preset feature processing algorithms; In the search space of the processing algorithm, the first hyperparameter set and the second hyperparameter set are tuned and searched to obtain the value of each first hyperparameter in the first hyperparameter set and the value of each hyperparameter in the second hyperparameter set. The value of the second hyperparameter; according to the feature processing algorithm corresponding to the value of each first hyperparameter and the data source of the feature processing algorithm, a feature processing flow is established, wherein, each first hyperparameter in the first hyperparameter set The order between indicates the execution order of the corresponding feature processing algorithm. Through the technical solution of the present disclosure, the automatic establishment of the feature processing flow can be realized, which can better adapt to the characteristics of the actual training data, thereby improving the training effect of the machine learning model.

Description

technical field [0001] The present disclosure relates to the field of machine learning, and in particular, relates to a method, device, storage medium and electronic equipment for establishing a feature processing flow. Background technique [0002] Machine learning usually includes data preprocessing, feature processing, model training, model fusion, model selection, model deployment and application, etc. Among them, the feature processing process directly determines the final model effect, and this process is very complicated, usually involving PCA (Principal Component Analysis, principal component analysis), Fast_ICA (Independent Component Analysis, independent component analysis), polynomial conversion, target coding, Truncated SVD (Singular Value Decomposition, singular value decomposition) and many other algorithms. [0003] The feature processing process in the prior art is usually performed according to a fixed linear processing flow. However, this fixed linear proc...
