Abstract

Mahalanobis distance οଶ values are commonly in the range of 0 to ൅λ where higher values represent greater distance between class means or points. The increase in Mahalanobis distance is unbounded as the distance multiply.To certain extend, the unbounded distance values pose difficulties in the evaluation and decision for instance in the sensors closeness test.This paper proposes an approach to [0, 1] bounded Mahalanobis distance οଶ that enable researcher to easily perform sensors closeness test.The experimental data of four different types of rice based on three different electronic nose sensors namely InSniff, PEN3, and Cyranose320 were analyzed and sensor closeness test seems successfully performed within the [0, 1] bound.
