The distributions of α values. The distributions of α values of each diagnostic trial in the 5-fold cross validation for three data sets. The skewness of sample label distribution leads to the skewness of the distributions of α values of the diagnoses of the BreastIBC and Kidney data sets. The signs of the α values indicate the group property of corresponding support vectors. As such, more support vectors can be found for the majority-count type, which will increase the likelihood of an unknown sample to be detected as the majority-count type in diagnosis
