In probability theory, fractional Brownian motion (fBm), also called a fractal Brownian motion, is a generalization of Brownian motion. Unlike classical Brownian motion, the increments of fBm need not be independent. fBm is a continuous-time Gaussian process BH(t) on [0, T], that starts at zero, has expectation zero … See more Prior to the introduction of the fractional Brownian motion, Lévy (1953) used the Riemann–Liouville fractional integral to define the process where integration is … See more • Brownian surface • Autoregressive fractionally integrated moving average • Multifractal: The generalized framework of fractional Brownian motions. • Pink noise See more Self-similarity The process is self-similar, since in terms of probability distributions: See more Practical computer realisations of an fBm can be generated, although they are only a finite approximation. The sample paths chosen can be thought of as showing discrete sampled points on an fBm process. Three realizations are shown below, each with … See more • Sainty, P.

To fill this gap, in this study, we propose an entropy-based estimator of the Hurst exponent relying on distributive features of the series in fractional Brownian motion (fBm), which is the key model of long-term memory processes.
