An Empirical Comparison of V-fold Penalisation and Cross Validation for Model Selection in Distribution-Free Regression
Charanpal Dhanjal, Nicolas Baskiotis, Stéphan Clémençon +1
Model selection is a crucial issue in machine-learning and a wide variety of penalisation methods (with possibly data dependent complexity penalties) have recently been introduced…
Dynamic recommender system : using cluster-based biases to improve the accuracy of the predictions
Modou Gueye, Talel Abdessalem, Hubert Naacke
It is today accepted that matrix factorization models allow a high quality of rating prediction in recommender systems. However, a major drawback of matrix factorization is its sta…
Moment formulae for general point processes
Laurent Decreusefond, Ian Flint
The goal of this paper is to generalize most of the moment formulae obtained in [Pri11]. More precisely, we consider a general point process μ, and show that the relevant quantitie…
Dissemination of Health Information within Social Networks
Charanpal Dhanjal, Sandrine Blanchemanche, Stéphan Clémençon +2
In this paper, we investigate, how information about a common food born health hazard, known as Campylobacter, spreads once it was delivered to a random sample of individuals in Fr…
Convergence to stable laws in the space
François Roueff, Philippe Soulier
We study the convergence of centered and normalized sums of i.i.d. random elements of the space of c{á}dl{á}g functions endowed with Skorohod's topology, to st…
Experimental demonstration of long-distance continuous-variable quantum key distribution
Paul Jouguet, Sébastien Kunz-Jacques, Anthony Leverrier +2
Distributing secret keys with information-theoretic security is arguably one of the most important achievements of the field of quantum information processing and communications. T…
