Retrieving the structure of probabilistic sequences of auditory stimuli from EEG data
Noslen Hernández, Aline Duarte, Guilherme Ost +3
Using a new probabilistic approach we model the relationship between sequences of auditory stimuli generated by stochastic chains and the electroencephalographic (EEG) data acquire…

Fluctuations for Spatially Extended Hawkes Processes
Julien Chevallier, Guilherme Ost
In a previous paper, it has been shown that the mean-field limit of spatially extended Hawkes processes is characterized as the unique solution of a neural field equation…

Sparse space-time models: Concentration Inequalities and Lasso
Guilherme Ost, Patricia Reynaud-Bouret
Inspired by Kalikow-type decompositions, we introduce a new stochastic model of infinite neuronal networks, for which we establish sharp oracle inequalities for Lasso methods and r…
