WebCompared to cluster-based undersampling methods, clustering-based oversampling methods avoid the risk of missing instance information. However, it is worth noting that most of the current clustering-based oversampling WebApr 25, 2024 · In particular, a multiple-clustering-based undersampling framework is proposed to determine the set of cluster centroids that best represent the majority class, whose size is reduced to be on par with that of the minority. Initially, a pool of centroids is created using the concept of ensemble clustering that aims to obtain a collection of ...
Class-overlap undersampling based on Schur decomposition for …
WebJul 17, 2024 · Then the multi-class dataset was transformed into a two-class dataset. In this article, the undersampling technique based on the DPCA clustering algorithm is used to achieve static undersampling. The clustering algorithm represents a classic unsupervised machine learning method that clusters highly similar samples. WebThe Cluster-Based Undersampling (CBU) technique proposed by Das et al. [19] is aimed at solving the class imbalance problem by discarding majority instances in overlap regions of the training data. This is achieved by clustering the training dataset into some k clusters and discarding all majority class instances from clusters which ... fly racing f2
