Imbalance learning

WitrynaA novel hyperbolic geometric hierarchy-imbalance learning framework, named HyperIMBA, is proposed to alleviate the hierarchy-IMbalance issue caused by uneven hierarchy-levels and cross-hierarchy connectivity patterns of labeled nodes. Learning unbiased node representations for imbalanced samples in the graph has become a … WitrynaOversampling is a popular problem-solver for class imbalance learning by generating more minority samples to balance the dataset size of different classes. However, resampling in original space is ineffective for the imbalance datasets with class overlapping or small disjunction. Based on this, a novel oversampling technique …
