| titleOfInvention | Feature selection method, system, computer readable storage medium and electronic device |
| abstract | The present disclosure relates to a feature selection method, system, computer-readable storage medium, and electronic device. The method includes: acquiring a first feature subset, and determining a first evaluation index corresponding to the first feature subset; acquiring a second feature subset and a third feature subset; determining a second evaluation index corresponding to the third feature subset; When the second evaluation index is better than the first evaluation index, the update operation is performed; when it is determined that the first update cut-off condition is met, the current target feature subset is determined as the target input feature of the target model, otherwise, the third feature subset is determined as the target input feature of the target model. The set is determined as the new first feature subset, the second evaluation index is determined as the new first evaluation index, and the step of obtaining the second feature subset and the third feature subset is returned. In this way, the target input features of a better target model can be quickly and effectively screened, the dimension of the feature set can be greatly reduced, the problem of "dimension disaster" can be solved to a great extent, and the calculation efficiency can be improved. |
