Excluded-Mean-Variance Neural Decision Analyzer for Qualitative Group Decision Making

Figure 3

A variance influence function (VIF, 𝑓(𝛼𝑣_𝑖)) that decreases exponentially with increasing excluded-variance 𝑣_𝑖. The gain 𝛼 represents the importance of the variance, (3). As 𝛼 increases, the slope of the VIF becomes steeper.
