In this thesis, we investigated a sequential decision making problem. We tested
different policies for online portfolio optimization: for a given number of assets and
a time horizon, the weights on assets are rebalanced at every time step according to

We explore, in increasing complexity, various strategies for addressing the Multi-
Armed Bandit Problem in order to find the algorithm that maximizes the clickthrough
rate in the Exploration and Exploitation Challenge 3 competition. The data used
result from the actions…

OBJECTIVE:
To determine how often clinical research from doctoral degree programmes is unpublished and to see if one can characterise differences between those researchers who do or do not publish their work or between the institutions where they studied.
DESIGN:

Most knowledge representation languages are based on classes and taxonomic relationships between classes. Taxonomic hierarchies without defaults or exceptions are semantically equivalent to a collection of formulas in first order predicate calculus. Although designers of knowledge representation languages often express…

This paper reports work in progress on an experimental text editor called CREF, the Cross Referenced Editing Facility. CREF deals with chunks of text, called segments, which may have associated features such as keywords or various kinds of links to…

With the rapid increase in low-cost and sophisticated digital technology the need for techniques to authenticate digital material will become more urgent. In this paper we address the problem of authenticating digital signals assuming no explicit prior knowledge of the…

We consider the scheduling problem of minimizing the average weighted completion time of n jobs with release dates on a single machine. We first study two linear programming relaxations of the problem, one based on a time-indexed formulation, the other…

La teoría de los campos conceptuales de Vergnaud, es un referente utilizado con gran éxito en los últimos años (André, 2004; Escudero, Moreira y

Caballero, 2009; Meleán, Arrieta y Escalona, 2010; entre otros). El propósito de este trabajo…
