Inverse problem for multivariate time series using dynamical latent variables

Zamparo, M.; Stramaglia, S.; Banavar, J.R.; Maritan, A. - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 11, pp. 3159-3169

Factor analysis is a well known statistical method to describe the variability among observed variables in terms of a smaller number of unobserved latent variables called factors. While dealing with multivariate time series, the temporal correlation structure of data may be modeled by including...

Optimal traffic networks topology: A complex networks perspective

Wu, Jian-Jun; Gao, Zi-You; Sun, Hui-jun - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 4, pp. 1025-1032

We investigate and analyse an optimal traffic network structure for resisting traffic congestion with different volumes of traffic. For this aim, we introduce a cost function and user-equilibrium assignment (UE) which ensures the flow balance on traffic systems. Our finding is that an optimal...
