A talk in Nice (on May 12, 2011, in French)
Petites perturbations des estimateurs et bornes PAC-Bayésiennes
Some lecture notes on PAC-Bayes bounds (Statistical learning, L3, ENS)
last updated on 09/15/2011
My talk at ENS on March 16, 2011 (in French)
Apprentissage PAC-Bayésien : de la classification à la régression
My talk in Lille on January 21, 2011
La moyenne empirique est-elle perfectible ?
My last preprints are on arXiv (and HAL)
Challenging the empirical mean and empirical variance: a deviation study,
Olivier Catoni (2010), on arXiv
High confidence estimates of the mean of heavy-tailed real random variables,
Olivier Catoni (2009), on arXiv .
This one can be skipped : it is an early draft of the previous preprint, which presents improved
estimators, improved bounds and some experiments.
Robust linear least squares regression, Jean-Yves Audibert, Olivier Catoni
(2010), on arXiv
Robust linear regression through PAC-Bayesian truncation, Jean-Yves Audibert,
Olivier Catoni (2010), on arXiv
Risk bounds in linear regression through PAC-Bayesian truncation,
Jean-Yves Audibert, Olivier Catoni (2009), on
arXiv.
This one can be skipped also: it is an early draft covering the
matter of the two previous preprints.

Preprints
I moved in October 1998 from ENS to Paris 6 and back to ENS in september 2008.
My older preprints and those
of some of my students
(Cécile Cot, Gilles Blanchard and Jean-Philippe Vert
who stayed at the ENS) can be found on the
preprint server of the
Laboratoire de Mathématiques de l'Ecole Normale Supérieure
de Paris.
Preprints from the period october 1998 - september 2008 are on the
server of the laboratoire de Probabilités et
Modèles Aléatoires., on the server
HAL or on ArXiv
You can also use the
national preprint search engine
of the cellule mathdoc.
The
last revision of ``The loop erased exit path and the metastability of
a biased vote process'', a joint paper with
Dayue Chen and Jun Xie, to appear in
Stochastic Processes and their Applications, is
also available.
Click here
for the last revision of ``Free energy estimates and deviation inequalities'',
with a more precise study of the unbounded case and improved bounds for Markov
chains.
The last revision of Gibbs estimators describes
general integrability conditions under which it is possible to define a Gibbs
estimator and to bound its risk.
Lecture notes
You can download the last revision of my
lecture notes
on ``Simulated Annealing Algorithms and Markov chains with Rare
Transitions'', published in the Séminaire de Probabilités.
You can download here the draft of my Saint-Flour
lecture notes (July 2001) on statiscial learning theory and stochastic
optimization. The final version of these notes is now published
as
Springer Lecture Notes in Mathematics Number 1851.
Please consider buying the book or encouraging your
library to buy it if you liked the draft !
(as a courtesy to Springer's efforts to make the Saint Flour
summer school notes widely available: authors don't get royalties
on lecture notes, this is why I feel free to give you this piece
of advice).
Information theory, statistical learning and pattern recognition
A workshop on this theme was held at the CIRM in December 1998.
The program of this meeting is kept here.
The Gibbs estimator in action : a downloadable software for density estimation
I wrote a software to illustrate a communication I presented
to Foundations of Computational Mathematics (July 13-17 2000, Hong-Kong).
You can have a look at its documentation here,
where you will also find download instructions.
The slides of my talk.
Empirical complexity and randomized estimators
You can download here the slides (as a .dvi or
.pdf file) of
my talk at the workshop
« Statistical Learning in Classification and Model Selection »
EURANDOM, Eindhoven, The Netherlands
January 15-18, 2003, organized by
Prof.dr. R.D.Gill (Universiteit Utrecht/EURANDOM), Dr. P. Grünwald (CWI), Prof.dr A.W. van der Vaart (Vrije Universiteit Amsterdam/EURANDOM),
Dr. J. Lember (EURANDOM)
as well as the corresponding preprint (as a .dvi or
.pdf file),
(to be also available soon on the PMA server).
