Figure 2From: A new hierarchical method for inter-patient heartbeat classification using random projections and RR intervals Schematic representation of detecting ventricular ectopic beat (VEB). M random matrices were generated and the preprocessed heartbeats were projected onto them to compute random projections. SVM component classifiers were constructed based on each group of random projections and RR intervals. The type of heartbeat was determined using majority voting strategy to combine multiple SVM classifiers.Back to article page
