Weba series of subspaces by sampling the geodesic flow. We report results on three variants: i) the results of SGF reported in [1] (SGF rept.); ii) our implementa-tion using the recommended parameters in [1] (SGF impl.); iii) our implementation using the optimal di-mensionality automatically selected by our algorithm (SGF opti.).

WebJun 27, 2024 · This is an important feature as many applications require sampling from distributions that are supported on non-trivial manifolds, such as the Fisher–Bingham … WebSep 20, 2014 · A geodesic flow is often understood to mean the restriction of the flow $\ {S_t\}$ to $W^ {2n-1}$. In local coordinates a geodesic flow is described by a system of ordinary second-order differential equations, which, in the Riemannian case, have the form $$\frac {d^2x^i} {dt^2}+\sum_ {j,k}\Gamma_ {jk}^i (x_t)\frac {dx^j} {dt}\frac {dx^k} {dt}=0,$$ WebNov 24, 2024 · By sampling on the geodesic between the source and target domains, it has been heuristically argued and empirically tested that some intermediate points exhibited … chonradee kulthap
