Derivative-free online learning of inverse dynamics models
Diego Romeres, Mattia Zorzi, Raffaello Camoriano +2
This paper discusses online algorithms for inverse dynamics modelling in robotics. Several model classes including rigid body dynamics (RBD) models, data-driven models and semipara…
A Scalable Strategy for the Identification of Latent-variable Graphical Models
Daniele Alpago, Mattia Zorzi, Augusto Ferrante
In this paper we propose an identification method for latent-variable graphical models associated to autoregressive (AR) Gaussian stationary processes. The identification procedure…
An alternating minimization algorithm for Factor Analysis
Valentina Ciccone, Augusto Ferrante, Mattia Zorzi
The problem of decomposing a given covariance matrix as the sum of a positive semi-definite matrix of given rank and a positive semi-definite diagonal matrix, is considered. We pre…
Identification of Sparse Reciprocal Graphical Models
Daniele Alpago, Mattia Zorzi, Augusto Ferrante
In this paper we propose an identification procedure of a sparse graphical model associated to a Gaussian stationary stochastic process. The identification paradigm exploits the ap…
On the coupling of Model Predictive Control and Robust Kalman Filtering
Alberto Zenere, Mattia Zorzi
Model Predictive Control (MPC) represents nowadays one of the main methods employed for process control in industry. Its strong suits comprise a simple algorithm based on a straigh…
Robust Kalman Filtering: Asymptotic Analysis of the Least Favorable Model
Mattia Zorzi, Bernard C. Levy
We consider a robust filtering problem where the robust filter is designed according to the least favorable model belonging to a ball about the nominal model. In this approach, the…
The role of noise modeling in the estimation of resting-state brain effective connectivity
Giulia Prando, Mattia Zorzi, Alessandra Bertoldo +1
Causal relations among neuronal populations of the brain are studied through the so-called effective connectivity (EC) network. The latter is estimated from EEG or fMRI measurement…
