Review and Comparison of Ellipsoidal Bounding Algorithms
1996This chapter is concerned with the problem of robust system identification when no statistical information is available on the noise, but only a bound on its instantaneous values is known. First, various ellipsoidal outer bounding (EOB) algorithms are presented in a unified way.

Neural network training with optimal bounded ellipsoid algorithm
Neural Computing and Applications, 2008Compared to normal learning algorithms, for example backpropagation, the optimal bounded ellipsoid (OBE) algorithm has some better properties, such as faster convergence, since it has a similar structure as Kalman filter. OBE has some advantages over Kalman filter training, the noise is not required to be Guassian.

On equivalence of major relaxation methods for minimum ellipsoid covering intersection of ellipsoids
at - Automatisierungstechnik, 2019This paper investigates the problem on the minimum trace or volume ellipsoid covering intersection of ellipsoids. This problem can be solved by three major relaxation methods involving semi-definite programming relaxation, S-procedure relaxation and ...

Rejection of Bounded Disturbances via Invariant Ellipsoids Technique
Proceedings of the 45th IEEE Conference on Decision and Control, 2006In this paper an approach based on invariant ellipsoids is applied to the problem of persistent disturbance rejection by means of static state-feedback control. Dynamic system is supposed to be linear time-invariant and affected by unknown-but-bounded exogenous disturbances.

$Q$ Bounds for Planar and Ellipsoidal Antennas
IEEE Transactions on Antennas and Propagation, 2017The procedure for numerically deriving equivalent circuits for the six lowest-order modes of arbitrarily shaped, electrically small antennas is reviewed. Element values and the effective radius are tabulated for thin prisms, spheroids, and ellipsoids with a wide range of aspect ratios.

Recent developments in optimal bounding ellipsoidal parameter estimation
Mathematics and Computers in Simulation, 1990Abstract The Optimal Bounding Ellipsoid (OBE) algorithms are viable alternatives to conventional adaptive filtering algorithms in situations where the noise does not satisfy the usual stationarity and whiteness assumptions. An example is shown in which the performance of an OBE algorithm is seen to be markedly superior to that of the recursive least ...

Updating of Bounding Ellipsoids Cut Simultaneously by Two Non-Parallel Linear Bounds
IFAC Proceedings Volumes, 2000Abstract An algorithm is presented to compute the minimum-volume ellipsoid, from a parametric family, containing the intersection of an ellipsoid and the region between two non-parallel hyperplanes. The ellipsoid is optimised by solving a cubic equation, rather than the quadratic in the case where the hyperplanes are parallel; the rest of the ...
