클러스터 평가 외부기준 척도 F<sub>n</sub>-Measure

F-Measure is one of the external measures for evaluating the validity of clustering results. Though it has clear advantages over other widely used external measures such as Purity and Entropy, F-Measure has inherently been less sensitive than other validity measures. This insensitivity owes to the definition of F-Measure that counts only most influential portions. In this research, we present F<sub>n</sub>-Measure, an external cluster evaluation measure based on F-Measure. F<sub>n</sub>-Measure is so sensitive that it can detect their difference in the cases that F-Measure cannot detect the difference in clustering results. We compare F<sub>n</sub>-Measure to F-Measure for a few clustering results and show which measure draws better result based upon homogeneity and completeness.
