Sentence examples for class unbalance from inspiring English sources
We explored several algorithms and various training sets with different positive/negative ratios in order to reach a good compromise between the actual underlying class unbalance (most protein pairs are not expected to be functionally related).
The observed relatively low precision can be explained by taking into account that it is more negatively affected by class unbalance and, in the Eukarya-net network task, the positives are at most 100 while the number of vertices in the network is 202,442 (i.e. the positives are less than 0.05% of the vertices at best).

When compared to those from normal donors, the networks of resistant and sensitive classes appeared quite similar; on the contrary, the direct comparison between resistant and sensitive classes identified differences that could unbalance the functional equilibrium of the AM network (e.g., the down regulation of many proapoptotic genes) (Table 3, Figure 3).
It is due to the unbalance between the classes.
Although the idea of secondary data incorporation is applicable to any kernel method or method that can be kernelized, we present results for the weighted Least Squares Support Vector Machine (LS-SVM), a method for supervised classification that takes the typical unbalance in many two-class problems into account [27] [29].
Due to the fact that one animal is left out, the unbalance in animals per disease class may be larger.
