A Correction Method of a Base Classifier Applied to Imbalanced Data Classificationinition of the soft neighbourhood of the classified object. The first approach is to change the neighbourhood to be more local by changing the Gaussian potential function approach to the nearest neighbour rule. The second one is to weight the instances that are included in the neighbourhood. The ins作者: 不開心 時(shí)間: 2025-3-22 23:32
