Quantities of Interest for Surface based Resistivity Geophysical Measurements Authors: Alvarez-Aramberri, J.,Bakr, S.A.,Pardo, D.,Barucq, H. The objective of traditional goal-oriented strategies is to construct an optimal mesh that minimizes the problem size needed to achieve a user prescribed tolerance error for a given quantity of interest (QoI). Typical geophysical resistivity measurement acquisition systems can easily record… Elsevier BV	2015-01-01

Multi-objectivising the Quadratic Assignment Problem by Means of an Elementary Landscape Decomposition Authors: Jose A. Lozano,Alexander Mendiburu,Josu Ceberio,Borja Calvo In the last decade, many works in combinatorial optimisation have shown that, due to the advances in multi-objective optimisation, the algorithms in this field could be used for solving single-objective problems.

Multiple-time-stepping generalized hybrid Monte Carlo methods Authors: Bruno Escribano,Elena Akhmatskaya,Sebastian Reich,Jon M. Azpiroz Performance of the generalized shadow hybrid Monte Carlo (GSHMC) method [1], which proved to be superior in sampling efficiency over its predecessors [2-4], molecular dynamics and hybrid Monte Carlo, can be further improved by combining it with multi-time-stepping (MTS) and mollification of slow… Elsevier BV	2015-01-01
A Novel Weakly Supervised Problem: Learning from Positive-Unlabeled Proportions Authors: Jerónimo Hernández-González,Iñaki Inza,Jose A. Lozano Standard supervised classification learns a classifier from a set of labeled examples. Alternatively, in the field of weakly supervised classification different frameworks have been presented where the training data cannot be certainly labeled. In this paper, the novel problem of learning from… Springer International Publishing	2015-01-01
