COSMIC: fast closed-form identification from large-scale data for LTV systems
Maria Carvalho, Claudia Soares, Pedro Lourenço +1
We introduce a closed-form method for identification of discrete-time linear time-variant systems from data, formulating the learning problem as a regularized least squares problem…
