Solving Support Vector Machines in Reproducing Kernel Banach Spaces with Positive Definite Functions
support vector machine reproducing kernel Banach space reproducing kernel,posi-tive definite function Fourier transform,Sobolev space,Matern function,Sobolev spline
2012/11/22
In this paper we extend support vector machines from reproducing kernel Hilbert spaces into reproducing kernel Banach spaces whose reproducing kernels can be defined on nonsymmetric domains. Using the...
Magnitude is a numerical invariant of finite metric spaces, recently introduced by T. Leinster, which is analogous in precise senses to the cardinality of finite sets or the Euler characteristic of to...
Norm and anti-norm inequalities for positive semi-definite matrices
Matrix operator trace symmetric norm symmetric anti-norm
2011/2/25
Some subadditivity results involving symmetric (unitarily invariant) norms are obtained. For instance, if g(t) =Pm k=0 aktk is a polynomial of degree m with non-negative coefficients, then, for all po...
Eigenvalue estimates for singular left-definite Sturm-Liouville operators
turm-Liouville operator left-definite eigenvalue estimate
2011/2/23
The spectral properties of a singular left-definite Sturm-Liouville operator JA are investigated and described via the properties of the corresponding right-definite selfadjoint counterpart A which is...
Entanglement transitions in random definite particle states
entanglement transitions Quantum Physics
2010/11/8
Entanglement within qubits are studied for the subspace of definite particle states or definite number of up spins. A transition from an algebraic decay of entanglement within two qubits (1/N^2) with ...
A new Lax-Oleinik type semigroup for time-periodic positive definite Lagrangian systems
Lax-Oleinik type semigroup time-periodic positive definite Lagrangian systems
2010/11/15
In this paper we introduce a new Lax-Oleinik type semigroup associated with positive definite Lagrangian systems for both the time-independent case and the time-periodic case. We show that the new La...
On positive definite preserving linear transformations of rank $r$ on real symmetric matrices
positive definite linear transformations
2010/11/22
We study on what conditions on $B_k,$ \ a linear transformation of rank $r$ \label{form} T(A)=\sum_{k=1}^r\tr(AB_k)U_k where $U_k,\ k=1,2,..., r$ are linear independent and all positive definite; is p...
Robust Transceiver Design for K-Pairs Quasi-Static MIMO Interference Channels via Semi-Definite Relaxation
K-Pairs Quasi-Static MIMO Interference Channels Semi-Definite Relaxation
2010/12/9
In this paper, we propose a robust transceiver design for the K-pair quasi-static MIMO interference channel. Each transmitter is equipped with M antennas, each receiver is
equipped with N antennas.
A Trace Inequality for Positive Definite Matrices
Trace inequality positive definite matrices positive semidefinite matrices
2010/1/25
In this note we prove that when the following two conditions are met: (i) the matrices are structured as follows , , , (ii) , are positive definite matrices and , are positive semidefinite matric...
Derivation of the Laplace-Beltrami operator for the zonal polynomials of positive definite Hermitian matrix argument
Laplace-Beltrami operator linear structures
2010/9/14
Some aspects of the complex linear structure theory, extending the real case due to Magnus (1988), are defined and studied. This theory provides complete proofs of conjectures given in literature arou...
Nonnegative-definite covariance structures for which the least squares estimator is the best linear unbiased estimator
Nonnegative-definite covariance structures the least squares estimator
2010/9/15
For the Gauss-Markov model with E(y) = Xβ and Var(y) = V,we establish a new explicit characterization of the general nonnegative-definite covariance structure V such that the best
linear unbiased est...

A shift splitting concept is introduced and, correspondingly,
a shift-splitting iteration scheme and a shift-splitting
preconditioner are presented,
