Consistency of the maximum likelihood estimator for general hidden Markov models
Randal Douc, Eric Moulines, Jimmy Olsson +1
Consider a parametrized family of general hidden Markov models, where both the observed and unobserved components take values in a complete separable metric space. We prove that th…
Local matching indicators for transport with concave costs
Julie Delon, Julien Salomon, A. Sobolevskii
In this note, we introduce a class of indicators that enable to compute efficiently optimal transport plans associated to arbitrary distributions of demands and supplies in…
Information Flow in Secret Sharing Protocols
Elham Kashefi, Damian Markham, Mehdi Mhalla +1
The entangled graph states have emerged as an elegant and powerful quantum resource, indeed almost all multiparty protocols can be written in terms of graph states including measur…
Efficient Learning of Sparse Conditional Random Fields for Supervised Sequence Labelling
Nataliya Sokolovska, Thomas Lavergne, Olivier Cappé +1
Conditional Random Fields (CRFs) constitute a popular and efficient approach for supervised sequence labelling. CRFs can cope with large description spaces and can integrate some f…
Training-Based Schemes are Suboptimal for High Rate Asynchronous Communication
Venkat Chandar, Aslan Tchamkerten, Gregory W. Wornell
We consider asynchronous point-to-point communication. Building on a recently developed model, we show that training based schemes, i.e., communication strategies that separate syn…
Detection and localization of change-points in high-dimensional network traffic data
Céline Lévy-Leduc, François Roueff
We propose a novel and efficient method, that we shall call TopRank in the following paper, for detecting change-points in high-dimensional data. This issue is of growing concern t…
