We study the effect of working with Support Vector Machines (SVM) and compare its performance with a reference detector based on Gaussian Mixture Models (GMM). These classifications methods require two previous stages: preprocessing and feature extraction. Firstly, we apply a preprocessing over the ECG for estimating the R instants which is previous to feature extraction. Secondly, a power-ratio-based coefficient (PRC) and a Linear Frequency Cepstral Coefficients (LFCC) parameterization over the RR signal is applied to extract the relevant characteristics. We fix the set of features for both classification methods. | URI: | http://hdl.handle.net/10553/44102 | ISSN: | 1109-2750 | Fuente: | WSEAS Transactions on Computers[ISSN 1109-2750],v. 5(1), p. 121-124 |
