The zero bias conductance anisotropy in the V/MgO/Fe system at 0.3 K has been thoroughly studied by using two methods: (i) estab- lishing three different remanent

For instance, the best overall accuracy of bagging in Breast with 20% noise is achieved using a 10% sampling ratio: The test error goes from 4.1% when no noise is injected to 3.5%

In particular, different versions of the training set for the base learners can be used, as in bagging (bootstrap sampling of training data), class-switching (noise injection in
