How to tune the RBF SVM hyperparameters? An empirical evaluation of 18 search algorithms
(Springer, 2021)
SVM with an RBF kernel is usually one of the best classification algorithms for most data sets, but it is important to tune the two hyperparameters C and γ to the data itself. In general, the selection of the hyperparameters ...
A hybrid image restoration algorithm based on Projections onto Convex Sets and Harmony Search
(2013-09-09)
Image restoration is a research field that attempts to recover a blurred and noisy image. Since it can be modeled as a linear system, we propose in this paper to use the meta-heuristics optimization algorithm Harmony Search ...

Differentially Private Stochastic Optimization: New Results in Convex and Non-Convex Settings
(2021)
We study differentially private stochastic optimization in convex and non-convex settings. For the convex case, we focus on the family of non-smooth generalized linear losses (GLLs). Our algorithm for the $\ell_2$ setting ...
Inexact spectral projected gradient methods on convex sets

An outcome space approach for generalized convex multiplicative programs

Equivalence of Convex Problem Geometry and Computational Complexity in the Separation Oracle Model
(INFORMS, 2009)
Consider the supposedly simple problem of computing a point in a convex set that is conveyed by a separation oracle with no further information (e. g., no domain ball containing or intersecting the set, etc.). The authors' ...
An application of CHA to concurrent short-term transmission expansion & reactive power planning
(2011-10-05)
In this paper a heuristic technique for solving simultaneous short-term transmission network expansion and reactive power planning problem (TEPRPP) via an AC model is presented. A constructive heuristic algorithm (CHA) ...
