Abstract

The invention relates to a feature processing flow establishment method and device, a storage medium and electronic equipment, and the method comprises the steps: obtaining a first hyper-parameter setand a second hyper-parameter set according to the number of preset feature processing algorithms; Performing tuning search on the first hyper-parameter set and the second hyper-parameter set in a search space of a feature processing algorithm to obtain a value of each first hyper-parameter in the first hyper-parameter set and a value of each second hyper-parameter in the second hyper-parameter set; And according to the feature processing algorithm corresponding to the value of each first hyper-parameter and the data source of the feature processing algorithm, establishing a feature processingflow, wherein the sequence between the first hyper-parameters in the first hyper-parameter set indicating the execution sequence of the corresponding feature processing algorithm. By means of the technical scheme, automatic establishment of the feature processing flow can be achieved, the method can better adapt to the characteristics of actual training data, and therefore the training effect ofthe machine learning model is improved.

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...
