A dimensional acceleration of gradient descent-like methods, using persistent random walkers
Vincent Tejedor
Finding a local minimum or maximum of a function is often achieved through the gradient-descent optimization method. For a function in dimension d, the gradient requires to compute…
First passage properties in a crowded environment
Vincent Tejedor
We develop a model to compute the first-passage time of a random walker in a crowded environment. Hard-core particles with the same size and diffusion coefficient than the tracer d…
Optimizing persistent random searches
V. Tejedor, R. Voituriez, O. Bénichou
We consider a minimal model of persistent random searcher with short range memory. We calculate exactly for such searcher the mean first-passage time to a target in a bounded domai…
Residual mean first-passage time for jump processes: theory and applications to Lévy flights and fractional Brownian motion
Vincent Tejedor, Olivier Bénichou, Ralf Metzler +1
We derive a functional equation for the mean first-passage time (MFPT) of a generic self-similar Markovian continuous process to a target in a one-dimensional domain and obtain its…
Close or connected? Distance and connectivity effects on transport in networks
Vincent Tejedor, Olivier Bénichou, Raphael Voituriez
We develop an analytical approach which provides the dependence of the mean first-passage time (MFPT) for random walks on complex networks both on the target connectivity and on th…
In vivo anomalous diffusion and weak ergodicity breaking of lipid granules
Jae-Hyung Jeon, Vincent Tejedor, Stas Burov +5
Combining extensive single particle tracking microscopy data of endogenous lipid granules in living fission yeast cells with analytical results we show evidence for anomalous diffu…
