Higuchi algorithm

WebOct 15, 2024 · The Higuchi algorithm requires a pre-defined k m a x value as an input, along with the target time-series. This value is usually determined by sampling the results returned by different values of k m a x and selecting a value based on the range of k m a x where the fractal dimension is stable. WebThe methods used are Katz algorithm, Higuchi algorithm and the Hurst exponent calculated using the rescaled range (R/S) analysis. Furthermore, the effects of the window size, the base waveform used and score-level fusion with Mel frequency cepstral coefficients (MFCC) has also been evaluated. The features have been extracted from two different ...
