Sampling geodesic flow
WebA standard “sampling importance resampling” (SIR) particle filter is comprised of two steps. In the motion update step, particles are propagated according to the motion model, while the weights remain fixed. In the information update step, ...

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.).

Webnegative then the geodesic flow is an Anosov flow [2] and w1(M) has ex-ponential growth [9]. It is because entropy describes the way geodesics spread out that sectional curvature seems the most relevant type of curva-ture. COROLLARY [8]. The compact fundamental domain N determines a set of generators IF= f{a e w1(M); aNf NN 0}. Let w(k) be the ... Web2.2. The Geometry of the Geodesic Flow. Let (Mn,g) be a Riemannian man-ifold with metric g = (g ij). One way to place the geodesic equations of M into the context of Hamiltonian dynamics is to look at the cotangent bundle T∗M. We put the canonical symplectic structure on T ∗M and define the Hamiltonian H on T M in local coordinates by H(x ...
