Synchronous deautoconvolution algorithm for discrete-time positive signals via I-divergence approximation
Lorenzo Finesso, Peter Spreij
We pose the problem of the optimal approximation of a given nonnegative signal with the scalar autoconvolution of a nonnegative signal , where and …
The inverse problem of positive autoconvolution
Lorenzo Finesso, Peter Spreij
We pose the problem of approximating optimally a given nonnegative signal with the scalar autoconvolution of a nonnegative signal. The I-divergence is chosen as the optimality crit…
Approximation of nonnegative systems by moving averages of fixed order
Lorenzo Finesso, Peter Spreij
We pose the approximation problem for scalar nonnegative input-output systems via impulse response convolutions of finite order, i.e. finite order moving averages, based on repeate…
Approximation of Nonnegative Systems by Finite Impulse Response Convolutions
Lorenzo Finesso, Peter Spreij
We pose the deterministic, nonparametric, approximation problem for scalar nonnegative input/output systems via finite impulse response convolutions, based on repeated observations…
Two-step Nonnegative Matrix Factorization Algorithm for the Approximate Realization of Hidden Markov Models
L. Finesso, A. Grassi, P. Spreij
We propose a two-step algorithm for the construction of a Hidden Markov Model (HMM) of assigned size, i.e. cardinality of the state space of the underlying Markov chain, whose -…
Approximation of stationary processes by Hidden Markov Models
Lorenzo Finesso, Angela Grassi, Peter Spreij
We aim at the construction of a Hidden Markov Model (HMM) of assigned complexity (number of states of the underlying Markov chain) which best approximates, in Kullback-Leibler dive…
