Issue of weighted averaging method for balanced and unbalanced committee member sensitivities to gearbox faults.

Balanced Member Sensitivities to Gearbox Faults	Committee Member 1	Committee Member 2	Average Output Probability (P₃) for d₃
Fault d₃	trained	trained	$P_{3} = \frac{w_{1} ρ_{1 - 2} + w_{2} ρ_{2 - 2}}{w_{1} + w_{2}} \in [0 1]$ P₃ is a reasonable result
Output probability for d₃ for an unseen case	$ρ_{1 - 3} \in [0 1]$	$ρ_{2 - 3} \in [0 1]$
Unbalanced Member Sensitivities to Gearbox Faults	Committee Member 1	Committee Member 2	Average Output Probability (P₅) for d₅
Fault d₅	Unable to train	trained	$P_{5} = \frac{w_{1} ρ_{1 - 5} + w_{2} ρ_{2 - 5}}{w_{1} + w_{2}}$ P₅ is an unfair/unpredictable result
Output probability for d₅ for an unseen case	$ρ_{1 - 5}$ is unpredictable	$ρ_{2 - 5} \in [0 1]$

Remark: w₁ and w₂ are weights for Committee members 1 and 2 respectively; P₃ and P₅ are average output probabilities for d₃ and d₅ respectively.
