Web15 de nov. de 2016 · Cost-sensitive learning methods, such as the MetaCost procedure, deal with class-imbalance by incurring different costs for different classes (Ling & … WebWe particularly focus on the behavior of different machine-learning techniques and on the role of multi-class cost-sensitive learning in such a context. To this end, four different kernel methods are empirically compared, namely pairwise multi-class support vector machines (SVMs), two cost-sensitive multi-class SVMs and kernel-based ordinal …

Web6 de jan. de 2024 · Ensemble learning is an algorithm that utilizes various types of classification models. This algorithm can enhance the prediction efficiency of component models. However, the efficiency of combining models typically depends on the diversity and accuracy of the predicted results of ensemble models. However, the problem of multi … Web1 de jul. de 2024 · The MultiBoost algorithm [22] is based on the minimization of a new cost-sensitive multi-class loss function. However, it does not generalize any previous approaches and requires an imprecise pool of multi-class weak learners to work. In this paper we introduce a well founded multi-class cost-sensitive Boosting algorithm, … easter dinner wine pairing
