Joint Reproduction Number and Spatial Connectivity Structure Estimation via Graph Sparsity-Promoting Penalized Functional
Etienne Lasalle, Barbara Pascal
During an epidemic outbreak, decision makers crucially need accurate and robust tools to monitor the pathogen propagation. The effective reproduction number, defined as the expecte…
Risk Estimate under a Time-Varying Autoregressive Model for Data-Driven Reproduction Number Estimation
Barbara Pascal, Samuel Vaiter
COVID-19 pandemic has brought to the fore epidemiological models which, though describing a wealth of behaviors, have previously received little attention in signal processing lite…
The Analytic Stockwell Transform and its Zeros
Ali Moukadem, Barbara Pascal, Jean-Baptiste Courbot +1
A recent original line of research in time--frequency analysis has shifted the interest in energy maxima toward zeros. Initially motivated by the intriguing uniform spread of the z…
Point Processes and spatial statistics in time-frequency analysis
Barbara Pascal, Rémi Bardenet
A finite-energy signal is represented by a square-integrable, complex-valued function of a real variable , interpreted as time. Similarly, a noisy signal is repr…
