Before revision:  Our approach capitalizes on the multi-frequency data ECIS provides, which have been underutilized in previous studies . We consider classification of fifteen different mammalian cell lines, construct a dictionary of 29 different characteristic features, and obtain 95\% accuracy out-of-sample .
After revision:  Our approach capitalizes on the multi-frequency ECIS data, where previous studies have focused on only one frequency. In classification tests on fifteen mammalian cell lines, construct a dictionary of 29 different characteristic features, and obtain 95\% accuracy out-of-sample .
