Localized principal components of natural images-an analytic solution

Network: Computation in Neural Systems, 1994
Summary: The structure of receptive fields in the visual cortex is believed to be shaped by unsupervised learning. A simple variant of unsupervised learning is the extraction of principal components. We derive analytically the form of the principal components of natural images.

Exact motion planning solution for principally kinematic systems

2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011
In this paper, we take a rather new approach to solving the motion planning problem for principally kinematic systems, that is, systems whose dynamics is completely specified by the right number of nonholonomic constraints. Given a planar curve in the Special Euclidean group, we analytically solve for the base variables that locomote the principally ...

Principal and nonprincipal solutions of impulsive differential equations with applications

Applied Mathematics and Computation, 2010
The authors consider the scalar impulsive equation \[ (r(t)z')'+ q(t)z= 0,\quad r(t)> 0,\tag{1} \] \[ \Delta r(t)z'+ q_iz= 0,\quad t=\theta_i,\quad t\geq t_0.\tag{2} \] The solutions \(u(t)\) and \(v(t)\) of (1), (2) are called principal and nonprincipal if \[ \lim_{t\to\infty} {u(t)\over v(t)}= 0,\;\int^\infty_0{dt\over ru^2}= \infty,\quad \int ...

The Principal/Agent Problem—Numerical Solutions

1988
The principal/agent paradigm provides a useful vehicle for examining a wide range of contractual relationships. Recent theoretical advances in the modeling of this relationship have enriched our understanding of the interplay between risk sharing and incentives in the design of optimal contracts.

Principal axes and principal moments of inertia from recent satellite gravity field solutions

2002
The Earth’s principal axes and principal moments of inertia were determined from the 2nd degree harmonic coefficients of recent Earth gravity field models and several values of the dynamical ellipticity. Closed exact formulae for the estimation of these parameters are developed based upon the exact analytical solution of eigenvalue-eigenvector problem ...

The principal variables of cryopreservation: solutions, temperatures, and rate changes

Fertility and Sterility, 2011
To describe several fundamental variables that influence ultimate survival of oocytes and embryos when they are cryopreserved.The literature describing fundamental and applied aspects of cryobiological variables that determine the responses of oocytes and embryos has been reviewed.When oocytes and embryos are to be cryopreserved, they are suspended in ...
