measure, sample entropy (SampEn), and have compared ApEn and SampEn by using them to analyze sets of random numbers with known probabilistic character. We have also evaluated cross-ApEn and cross-SampEn, which use cardio- vascular data sets to measure the similarity of two distinct ...
摘要: Evaluates a method for physiological time-series analysis using approximate entropy and sample entropy. Sample entropy and approximate entropy of random numbers with a uniform distribution; Calculation of the expected value of the key probability; Examination of different correction methods....
Sample entropy SEis a non-linear technique that measures the randomness of a series of data23. Compared to other approaches,SE’s main advantage is that it provides consistent results even in short and noisy medical time series19,23. To calculateSE, three parameters are necessary: the embedding...
Based on sample entropy, this paper presents an instance selection method for efficient data classification with extreme learning machine (ELM), which is used to train a SLFN. The proposed method is compared with four state-of-the-art approaches by a series of experiments. The experimental ...
Summary: Aiming at the problems of the radar emitter signal (RES) recognition based on intra-pulse feature, a novel entropy feature extraction approach is proposed. In this method the sample entropy (SampEn) and fuzzy entropy (FzzyEn) are presented to extract features from RES. The SampEn can...
