Abstract

In this paper a HMM based method for analysing curves of amperometric biosensors is presented. In addition to our multi-HMM approach, we propose an enhanced single-HMM approach, which is used to detect the curve type, the end of the measurement and the correct measurement position. Besides, a problem-specific modified variant of the Baum-Welch algorithm is presented. The multi- and single-HMM approach yielded good accuracies and recognition rates. The modified Baum-Welch algorithm outperformed the standard Baum-Welch.
