#### Data generation approaches for topic classification in multilingual spoken dialog systems

(2019)

The conception of spoken-dialog systems (SDS) usually faces the problem of extending or adapting the system to multiple languages. This implies the creation of modules specically for the new languages, which is a time ...

#### Characterising the rankings produced by combinatorial optimisation problems and finding their intersections

(2019)

The aim of this paper is to introduce the concept of intersection between combinatorial optimisation problems. We take into account that most algorithms, in their machinery, do not consider the exact objective function ...

#### A review on distance based time series classification

(2018-11-01)

Time series classification is an increasing research topic due to the vast amount of time series data
that is being created over a wide variety of fields. The particularity of the data makes it a challenging task
and ...

#### Bayesian inference for algorithm ranking analysis

(2018-08-30)

The statistical assessment of the empirical comparison of algorithms is an essential step in heuristic optimization. Classically, researchers have relied on the use of statistical tests. However, recently, concerns about ...

#### Distance-based exponential probability models on constrained combinatorial optimization problems

(2018-08-30)

Estimation of distribution algorithms have already demonstrated their utility when solving a broad range of combinatorial problems. However, there is still room for methodological improvements when approaching constrained ...

#### Detection of Sand Dunes on Mars Using a Regular Vine-based Classification Approach

(2018-08)

This paper deals with the problem of detecting sand dunes from remotely sensed images of the surface of Mars. We build on previous approaches that propose methods to extract informative features for the classification of ...

#### Are the artificially generated instances uniform in terms of difficulty?

(2018-06)

In the field of evolutionary computation, it is usual to generate artificial benchmarks of instances that are used as a test-bed to determine the performance of the algorithms at hand. In this context, a recent work on ...

#### A note on the behavior of majority voting in multi-class domains with biased annotators

(2018-05)

Majority voting is a popular and robust strategy to aggregate different opinions in learning from crowds, where each worker labels examples ac- cording to their own criteria. Although it has been extensively studied in the ...

#### Effects of reducing VMs management times on elastic applications

(2018-05)

Cloud infrastructures provide computing resources to applications in the form of Virtual Machines (VMs). Many applications deployed in cloud resources have an elastic behavior, that is, they change the number of servers ...

#### Spacecraft Trajectory Optimization: A review of Models, Objectives, Approaches and Solutions

(2018)

This article is a survey paper on solving spacecraft trajectory optimization problems. The solving process is decomposed into four key steps of mathematical modeling of the problem, defining the objective functions, ...
