Jan 5, 2021 · Random undersampling involves randomly selecting examples from the majority class and deleting them from the training dataset. In the random ...
Jan 28, 2021 · We present a novel hybrid approach for handling such datasets. We utilize simulated annealing algorithm for undersampling and apply support vector machine.
Jul 27, 2023 · The main objective of this study is to provide guidance on selecting optimal resampling methods in imbalanced and complex datasets to improve classification ...
Jul 3, 2024 · It is done by applying random under sampling to the majority class instances. These under sampled majority class instances and the minority ...
In the case of SVM high, but not complete, undersampling led to achieving the best results, with the best performance observed for the undersampling ratio of ...
For our undersampling proposal, we wanted to deal with multiclass hybrid and incomplete data, and we wanted our proposal to be computationally tractable.
