Although resampling techniques are widely applied to fit for MDR detecting epistasis in imbalanced data sets, the possible information missing by resampling is hard to be excluded.
AGC is a type of coefficient that contains class imbalance information, which can strengthen and weaken the gravitational field of the minority and majority classes.
The original 120 (single) features, which do not represent imbalance information, were not considered to guarantee that the discriminative information was indeed brought by imbalance information.
As depicted by Equation 2, the meta-features model imbalance information, as each value is the displacement of one score with respect to the other involved in the meta-feature.
In other words, these features are only interesting to distinguish between cases and controls when the imbalance information is considered, and their importance is not dominated by any of the features that are already known to be interesting.
It has recently been proposed that SNP arrays may be better suited for the determination of copy number states in tumor samples because the analysis of data derived from such arrays can make use of allelic imbalance information in addition to hybridization intensity [12].
Moreover, we planned to recruit the same number of participants in multiple settings, but the number of participants from each was imbalanced because of information saturation.
In the process of WELM classifier classification, the minority class samples are assigned with larger weight, which make the information of imbalanced class distribution is well perceived [28].
And the imbalance in information between lenders and borrowers is often great.
The imbalance of information and power in the doctor-patient relationship is enormous and the temptation to take shortcuts is human and ever-present.
