Why the study?
Motif detection in ECG signals requires improved methods for identifying repetitive patterns with better accuracy and execution time.
Does the proposed motif detection method using Particle Swarm Optimization improve accuracy and execution time in ECG signal analysis compared to existing methods?

A novel motif detection method using Particle Swarm Optimization improves the accuracy and execution time of ECG signal analysis.
May improve ECG motif detection computationally; leaves open clinical validation and outcome impact before practice adoption.
The motif discovery mechanism is used for the analysis of the ECG signal along with the efficient particle swarm optimization algorithm. In this method motif detection in the ECG signal sequences is presented. The proposed method is based upon the variable length of motif and detected the repetitive patterns in input ECG signal. This method has been visualized to analyse the signal data under the in-depth vigilant analytical method.Optimization of signals in the proposed method is performed by Particle Swarm Optimization technique (PSO) for improving the quality of signals. The data set used in this work is collected from the University of California, Riverside (UCR). The performance of the proposed method is measured using various parameters like Execution time, Precision, Recall and F1-measures. The performance of the proposed method is compared with existing methods in terms of accuracy and execution time. The Execution time and Accuracy of proposed method is in more improved form than the existing methods.

Ramandeep Kaur (2017) studied ECG signal analysis (n=200). Particle Swarm Optimization (PSO) based motif detection vs. Existing methods (Brute Force, Moen Keogh, Random Projection, MDLats) was evaluated on Execution time and accuracy (Precision, Recall, F1-measure). The proposed Particle Swarm Optimization-based motif detection method achieved up to 94% precision, 92.3% recall, and 93% F1-measure, with execution times ranging from 662 to 682 milliseconds, outperforming existing methods.
