WebMay 5, 2024 · Abstract. We propose and analyze an optimal mass transport method for a random genetic drift problem driven by a Moran process under weak selection. The continuum limit, formulated as a reaction-advection-diffusion equation known as the Kimura equation, inherits degenerate diffusion from the discrete stochastic process that conveys … WebApr 9, 2024 · Specifically, optimal choices of b-values have been widely studied for the mono-exponential diffusion model, 17, 18 and some studies have implemented similar optimization strategies on the IVIM model for applications in kidney, liver, and breast. 19-22 In brain, a recent study by Chabert and colleagues 14 has been conducted on volunteers ...

WebSep 24, 2024 · The OTDD relies on optimal transport (OT), a flexible geometric method for comparing probability distributions, and can be used to compare any two datasets, regardless of whether their label sets are directly comparable. As a bonus, the OTDD returns a coupling of the two datasets being compared, which can be understood as a set of soft ... Websatisfies a set of transport equation that will reduce to (PMEm) under a stronger convergence assumption (for the precise statement we refer to Theorem 3.8). To … WebFeb 1, 2024 · In this paper, we introduce a new technique called conditional flow matching (CFM), a simulation-free training objective for CNFs. CFM features a stable regression objective like that used to train the stochastic flow in diffusion models but enjoys the efficient inference of deterministic flow models. duracell battery ingredients
