Predicting links in ego-networks using temporal information
Lionel Tabourier, Anne-Sophie Libert, Renaud Lambiotte
Link prediction appears as a central problem of network science, as it calls for unfolding the mechanisms that govern the micro-dynamics of the network. In this work, we are intere…
Probabilistic cartography of the large-scale structure
Florent Leclercq, Jens Jasche, Guilhem Lavaux +1
The BORG algorithm is an inference engine that derives the initial conditions given a cosmological model and galaxy survey data, and produces physical reconstructions of the underl…
Photon dissociation into two and three jets: initial and final state corrections
R. Boussarie, A. Grabovsky, L. Szymanowski +1
We study the impact factor for the photon to quark, antiquark and gluon transition within Balitsky's shock-wave formalism. Our aim is to extend existing results beyond approximatio…
A comparison principle for PDEs arising in approximate hedging problems: application to Bermudan options
Géraldine Bouveret, Jean-François Chassagneux
In a Markovian framework, we consider the problem of finding the minimal initial value of a controlled process allowing to reach a stochastic target with a given level of expected…
Smoothness of moments of the solutions of discrete coagulation equations with diffusion
Maxime Breden, Laurent Desvillettes, Klemens Fellner
In this paper, we establish smoothness of moments of the solutions of discrete coagulation-diffusion systems. As key assumptions, we suppose that the coagulation coefficients grow…
Parallel Exhaustive Search without Coordination
Pierre Fraigniaud, Amos Korman, Yoav Rodeh
We analyze parallel algorithms in the context of exhaustive search over totally ordered sets. Imagine an infinite list of "boxes", with a "treasure" hidden in one of them, where th…
