For convex optimization problems deterministic first order methods have linear convergence provided that the objective function is smooth (Lipschitz continuous gradient) and strongly convex. Moreover, under the same conditions – smoothness and strong convexity – stochastic first order methods have sublinear convergence rates. However, in many applications (machine... Read More

Empirical risk minimization (ERM) problems express optimal classifiers as solutions of optimization problems in which the objective is the sum of a very large number of sample costs. Established approaches to solve ERM rely on computing stochastic gradient directions by accessing a single summand at each iteration. Despite the efficiency of individual iterations, these...

Responsible Business – Rebuilding Trust and Creating Value Over the last few decades, there's been a steady erosion of public trust in government and business institutions. In recent years, some of the biggest names in business have faced criticism, fines and, in some cases, even worse. While public trust in governments and business is weak, there is... Read More

ETEM-SG and ETEM-SC are recently proposed bottom-up models specifically designed to study the long term impact on urban energy systems of the Smart Grid (SG) and Smart City (SC) developments. These models can be considered as an outgrowth of the MARKAL/TIMES family of models. The massive penetration of distributed variable renewable energy technologies combined with... Read More

We present a model for clustering which combines two criteria: Given a collection of objects with pairwise similarity measure, the problem is to find a cluster that is as dissimilar as possible from the complement, while having as much similarity as possible within the cluster. The two objectives are combined either as a ratio or with linear weights. The ratio problem... Read More
