Most of the oversampling techniques operate in the Euclidean space implied by the attributes. Therefore, it is extremely important to normalize/scale the attributes appropriately. With no knowledge on the importance of attributes, the normalization/standardization is a good first try. Having some domain knowledge or attribute importance from bootstrap classification, the scaling of attribute ranges according to their importance is also reasonable. Alternatively, feature subset selection might also improve the results by oversampling work in the most suitable subspace.
Classification after oversampling is highly sensitive to the number of minority samples being generated. Balancing the dataset is rarely the right choice, as most of the classifiers operate the most efficiently if the density of positive and negative samples near the decision boundary is approximately the same. If the manifolds of the positive and negative classes do not have the same size approximately, balancing the dataset cannot achieve this. Moreover, in certain regions it can even revert the situation: if the manifold of the minority class is much smaller than that of the majority class, balancing will turn the minority class into the majority in the local environments along the decision boundary.
The solution is to apply model selection for the number of samples being generated. Almost all techniques implemented in the `smote-variants package have a parameter called proportion. This parameter controls how many samples to generate, namely, the number of minority samples generated is proportion*(N_maj - N_min), that is, setting the proportion parameter to 1 will balance the dataset. It is highly recommended to carry out cross-validated model selection for a range like proportion` = 0.1, 0.2, 0.5, 1.0, 2.0, 5.0.
