Hace 4 días · We describe a covariance predictor that has the form of a generalized linear model, i.e., an affine function of the features followed by an inverse link function that maps vectors to symmetric positive definite matrices. The log-likelihood is a concave function of the predictor parameters, so fitting the predictor involves convex optimization.
Hace 4 días · The proposed l1 trend filtering method} substitutes a sum of absolute values ( i.e., an l1-norm) for the sum of squares used in H-P filtering to penalize variations in the estimated trend. The l1 trend filtering method produces trend estimates that are piecewise linear, and therefore is well suited to analyzing time series with an underlying ...

Hace 4 días · Control system analysis and synthesis via linear matrix inequalities. Eckman lecture, American Control Conference, San Francisco, June 1993. Corresponding paper appeared in the same conference, 2:2147-2154. A wide variety of problems in systems and control theory can be cast or recast as convex problems that involve linear matrix inequalities ...
Hace 4 días · CVX, a Matlab toolbox for disciplined convex programming. Convex programming is a subclass of nonlinear programming (NLP) that unifies and generalizes least squares (LS), linear programming (LP), and convex quadratic programming (QP). It has become quite popular recently for a number of reasons, including its attractive theoretical properties ...
