Fault Identification of UHVDC Transmission Based on DF-AD and Ensemble Learning
| Algorithm 1: RF-RFECV | Input: data set samples , and classes labels | Output: optimal feature subset | (1): for in 1 : 5 do | (2): split the dataset samples into 5 groups, select the as test data, the RF model was trained by the other four groups | (3): train the random forest model | (4): calculate the accuracy of RF | (5): evaluate the MDI and remove the least import feature, update feature subset | (6): repeat step 4 to step 5 until the quantity of features of dataset is 0 | (7): end | (8): determine the optimal feature subset with highest accuracy of CV |
