To tree or not to tree? Assessing the impact of smoothing the decision boundaries
Anthea Mérida, Argyris Kalogeratos, Mathilde Mougeot
When analyzing a dataset, it can be useful to assess how smooth the decision boundaries need to be for a model to better fit the data. This paper addresses this question by proposi…
Online non-parametric change-point detection for heterogeneous data streams observed over graph nodes
Alejandro de la Concha, Argyris Kalogeratos, Nicolas Vayatis
Consider a heterogeneous data stream being generated by the nodes of a graph. The data stream is in essence composed by multiple streams, possibly of different nature that depends…
Epidemic Models for COVID-19 during the First Wave from February to May 2020: a Methodological Review
Marie Garin, Myrto Limnios, Alice Nicolaï +12
We review epidemiological models for the propagation of the COVID-19 pandemic during the early months of the outbreak: from February to May 2020. The aim is to propose a methodolog…
Model family selection for classification using Neural Decision Trees
Anthea Mérida Montes de Oca, Argyris Kalogeratos, Mathilde Mougeot
Model selection consists in comparing several candidate models according to a metric to be optimized. The process often involves a grid search, or such, and cross-validation, which…
Dynamic Epidemic Control via Sequential Resource Allocation
Mathilde Fekom, Nicolas Vayatis, Argyris Kalogeratos
In the Dynamic Resource Allocation (DRA) problem, an administrator has to allocate a limited amount of resources to the nodes of a network in order to reduce a diffusion process (D…
Optimal Multiple Stopping Rule for Warm-Starting Sequential Selection
Mathilde Fekom, Nicolas Vayatis, Argyris Kalogeratos
In this paper we present the Warm-starting Dynamic Thresholding algorithm, developed using dynamic programming, for a variant of the standard online selection problem. The problem…
