Nettetotherwise we would have done feature reweighting rather than instance reweighting. These key factors motivate us to work in the RKHS, which is natural for both requirements. 3.2.1 Dimensionality Reduction Dimensionality reduction methods can learn a transformed feature representation by minimizing the reconstruction er-ror of the input data. NettetMoreover, kernel mean matching is proposed for the first time for dynamic compensation based on an individual’s relevance in instance reweighting. The experimental results confirm that MODDA outperforms other state-of-the-art algorithms in terms of the classification accuracy for 16 well-known cross-domain tasks.
