PCA in Autocorrelation Space
The use of higher order autocorrelations as features for pattern classification has been usually restricted to second or third orders due to high computational costs. Since the autocorrelation space is a high dimensional space we are interested in reducing the dimensionality of feature vectors for the benefit of the pattern classification task. An established technique is Principal Component An...
متن کاملSpacelike hypersurfaces with constant $S$ or $K$ in de Sitter space or anti-de Sitter space
Let $M^n$ be an $n(ngeq 3)$-dimensional complete connected and oriented spacelike hypersurface in a de Sitter space or an anti-de Sitter space, $S$ and $K$ be the squared norm of the second fundamental form and Gauss-Kronecker curvature of $M^n$. If $S$ or $K$ is constant, nonzero and $M^n$ has two distinct principal curvatures one of which is simple, we obtain some charact...
متن کاملEarths: Rare in Time, Not Space?
We compare two recent astrobiological approaches to the solution of the problem of the “Great Silence” (or Fermi’s paradox): the “rare Earth” hypothesis of Ward and Brownlee, and the phase-transition scenario of Annis. We show that they have important similarities, as far as self-selection of intelligent observers is concerned. In order to better illuminate the differences, we consider the dura...
متن کاملInterior estimate on the space
Abstract. We will prove an interior estimate for the mappings on the space, which is generalization of the Heinz-Bernstein theorem for the plane. In other worlds we prove the theorem. Let s : Bn → R (s : Bn → Bm) be a continuous function from the closed unit ball Bn ⊂ R into the real line (closed unit ball in R) satisfying the conditions: (i) s is C on U, (ii) s is C in ∂B = Sn−1 and (iii) |∆s|...
متن کاملCemetery as a Sociocultural Space in the Persian Cities
Examining the planning of cemeteries in the urbanism system of Iran does not show a goodcondition. In fact, cemeteries in the most Persian cities have become large-scale open spaces outside the city. This couldcause irreparable damage to the cities because of the partial and/or improper use of the capacity of urban lands. Alongwith this, historical cemeteries within the cities have been abandon...
