Gaussian motion
WebApr 11, 2024 · This study presents a comprehensive approach to mapping local magnetic field anomalies with robustness to magnetic noise from an unmanned aerial vehicle (UAV). The UAV collects magnetic field measurements, which are used to generate a local magnetic field map through Gaussian process regression (GPR). The research identifies … WebMar 2, 2024 · We propose a generalization of the widely used fractional Brownian motion (FBM), memory-multi-FBM (MMFBM), to describe viscoelastic or persistent anomalous diffusion with time-dependent memory exponent $α(t)$ in a changing environment. In MMFBM the built-in, long-range memory is continuously modulated by $α(t)$. We derive …

A key fact of Gaussian processes is that they can be completely defined by their second-order statistics. Thus, if a Gaussian process is assumed to have mean zero, defining the covariance function completely defines the process' behaviour. Importantly the non-negative definiteness of this function enables … See more In probability theory and statistics, a Gaussian process is a stochastic process (a collection of random variables indexed by time or space), such that every finite collection of those random variables has a multivariate normal distribution See more The variance of a Gaussian process is finite at any time $${\displaystyle t}$$, formally See more There is an explicit representation for stationary Gaussian processes. A simple example of this representation is where See more A Gaussian process can be used as a prior probability distribution over functions in Bayesian inference. Given any set of N points in the … See more For general stochastic processes strict-sense stationarity implies wide-sense stationarity but not every wide-sense stationary … See more A Wiener process (also known as Brownian motion) is the integral of a white noise generalized Gaussian process. It is not stationary, but it has stationary increments. The Ornstein–Uhlenbeck process is a stationary Gaussian process. The See more In practical applications, Gaussian process models are often evaluated on a grid leading to multivariate normal distributions. Using these models … See more

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 for all t in [0, T], and has the following covariance function: where H is a real number in (0, 1), called the Hurst index or Hurst parameter associated with the … 7文字の動物WebOct 28, 2024 · Brownian motion is a central scientific paradigm.
