Parsimonious Volterra System Identification
Sarah Hojjatinia, Korkut Bekiroglu, Constantino M. Lagoa
In this short paper, we aim at developing algorithms for sparse Volterra system identification when the system to be identified has infinite impulse response. Assuming that the imp…
Randomized opinion dynamics over networks: influence estimation from partial observations
Chiara Ravazzi, Sarah Hojjatinia, Constantino M. Lagoa +1
In this paper, we propose a technique for the estimation of the influence matrix in a sparse social network, in which individual communicate in a gossip way. At each step, a ra…
Identification of Switched Autoregressive Systems from Large Noisy Data Sets
Sarah Hojjatinia, Constantino M. Lagoa, Fabrizio Dabbene
The paper introduces a novel methodology for the identification of coefficients of switched autoregressive linear models. We consider the case when the system's outputs are contami…
