Identification of anomalous diffusion sources by unsupervised learning
Fractional Brownian motion (fBm) is a ubiquitous diffusion process in which the memory effects of the stochastic transport result in the mean-squared particle displacement following a power law 〈Δr^{2}〉∼t^{α}, where the diffusion exponent α characterizes whether the transport is subdiffusive (α<1...
