Spectral analysis of business and consumer survey data
(2020-07-08)
External research report
Open AccessThe main objective of this study is two-fold. First, we aim to detect the underlying existing periodicities in business and consumer survey data. With this objective, we conduct a spectral analysis of all survey indicators. ... -
Economic determinants of employment sentiment: a socio-demographic analysis for the euro area
(2020-07-07)
External research report
Open AccessIn this study we construct quarterly consumer confidence indicators of unemployment for the euro area using as input the consumer expectations for sixteen socio-demographic groups elicited from the Joint Harmonised EU ... -
A regional perspective on the accuracy of machine learning forecasts of tourism demand based on data characteristics
(2018-07-03)
External research report
Open AccessIn this work we assess the role of data characteristics in the accuracy of machine learning (ML) tourism forecasts from a spatial perspective. First, we apply a seasonal-trend decomposition procedure based on non-parametric ... -
A geometric approach to proxy economic uncertainty by a metric of disagreement among qualitative expectations
(2018-07-10)
External research report
Open AccessIn this study we present a geometric approach to proxy economic uncertainty. We design a positional indicator of disagreement among survey-based agents' expectations about the state of the economy. Previous dispersion-based ... -
Let the data do the talking: empirical modelling of survey-based expectations by means of genetic programming
(2017-07-05)
External research report
Open AccessIn this study we use agents’ expectations about the state of the economy to generate indicators of economic activity in twenty-six European countries grouped in five regions (Western, Eastern, and Southern Europe, and ... -
Regional tourism demand forecasting with machine learning models: Gaussian process regression vs. neural network models in a multiple-input multiple-output setting”
(2017-07-06)
External research report
Open AccessThis study presents a multiple-input multiple-output (MIMO) approach for multi-step-ahead time series prediction with a Gaussian process regression (GPR) model. We assess the forecasting performance of the GPR model with ... -
Effects of removing the trend and the seasonal component on the forecasting performance of artificial neural network techniques
(2015-07-02)
External research report
Open AccessThis study aims to analyze the effects of data pre-processing on the performance of forecasting based on neural network models. We use three different Artificial Neural Networks techniques to forecast tourist demand: a ... -
Multiple-input multiple-output vs. single-input single-output neural network forecasting
(2015-07-09)
External research report
Open AccessThis study attempts to improve the forecasting accuracy of tourism demand by using the existing common trends in tourist arrivals form all visitor markets to a specific destination in a multiple-input multiple-output (MIMO) ... -
Self-organizing map analysis of agents’ expectations. Different patterns of anticipation of the 2008 financial crisis
(2015-07-03)
External research report
Open AccessBy means of Self-Organizing Maps we cluster fourteen European countries according to the most suitable way to model their agents’ expectations. Using the financial crisis of 2008 as a benchmark, we distinguish between those ... -
Regional forecasting with support vector regressions: the case of Spain
(2015-05-06)
External research report
Open AccessThis study attempts to assess the forecasting accuracy of Support Vector Regression (SVR) with regard to other Artificial Intelligence techniques based on statistical learning. We use two different neural networks and three ... -
Tourism demand forecasting with different neural networks models
(2013-07-16)
External research report
Open AccessThis paper aims to compare the performance of different Artificial Neural Networks techniques for tourist demand forecasting. We test the forecasting accuracy of three different types of architectures: a multi-layer ... -
Innovative mmWave transmissions schemes channel models and antennas
(2017-10-12)
External research report
Open AccessThe next generation (5G) of wireless communication will improve upon existing mobile communication standards significantly while taking into account the increasing amount of stress on the limited amount of available ...
