WitrynaSmoteR is a variant of SMOTE algorithm proposed by Torgo et al. (2013) to address the problem of imbalanced domains in regression tasks. This function uses the parameters rel and thr.rel, a relevance function and a relevance threshold for distinguishing between the normal and rare cases. The parameter C.perc controls the amount of over … WitrynaWe have briefly described infinitely imbalanced logistic regression. Now, we give a similar result for multinomial logistic regression with a specific highly imbalanced multi-class setting. This section is a preamble for our proposed relabeling approach; the result is important for the later EM calculation.
