When Biometrics Meet IoT: A Survey

Abstract

In this study, a hybrid forecasting model based on Empirical Mode Decomposition (EMD) and Least Squares Support Vector Machines (LSSVMs) is proposed to predict tourism demand (i.e. the maximal number of arrivals in a short time interval). The proposed approach first uses EMD decompose the complicated data into a finite set of Intrinsic Mode Functions (IMFs) and a residue, then the IMF components and residue are modeled and forecasted using Least Squares Support Vector Machines, next, the forecasting values are obtained by the sum of these prediction results. In order to evaluate the performance of the proposed approach, the maximal values of tourist arrive in 1 min time interval is used as an illustrative example. Experimental results show that the proposed model outperforms the single LSSVM model without EMD preprocessing. © 2014 Springer-Verlag Berlin Heidelberg..
