HORSESHOES IN MULTIDIMENSIONAL SCALING AND KERNEL METHODS。
In complex problems it may, however, be very expensive or infeasible to determine the Hessian matrix A.
This motivates quasi-Newton methods which recursively estimate A of A−1
from the measure...
Asynchronous Hybrid Systems with Jumps -- Analysis and Synthesis Methods
Synthesis Methods Analysis
<
2015/6/19
In this paper we show that the H-infinity synthesis problem for a class of linear systems with asynchronous jumps can be reduced to a purely discrete time synthesis problem. The system class considere...
Polynomial level-set methods for nonlinear dynamical systems analysis

<
2015/6/19
In this paper, we present a method for computing the domain of attraction for non-linear dynamical systems. We propose a level-set method where sets are represented as sublevel sets of polynomials. Th...
