Bayes meets Bernstein at the Meta Level: an Analysis of Fast Rates in Meta-Learning with PAC-Bayes

Charles Riou, Pierre Alquier, Badr-Eddine Chérief-Abdellatif

Bernstein's condition is a key assumption that guarantees fast rates in machine learning. For example, the Gibbs algorithm with prior has an excess risk in , as oppos…

PAC-Bayesian Offline Contextual Bandits With Guarantees

Otmane Sakhi, Pierre Alquier, Nicolas Chopin

This paper introduces a new principled approach for off-policy learning in contextual bandits. Unlike previous work, our approach does not derive learning principles from intractab…

Variance-Aware Estimation of Kernel Mean Embedding

Geoffrey Wolfer, Pierre Alquier

An important feature of kernel mean embeddings (KME) is that the rate of convergence of the empirical KME to the true distribution KME can be bounded independently of the dimension…

Optimal quasi-Bayesian reduced rank regression with incomplete response

The Tien Mai, Pierre Alquier

The aim of reduced rank regression is to connect multiple response variables to multiple predictors. This model is very popular, especially in biostatistics where multiple measurem…

Concentration of discrepancy-based approximate Bayesian computation via Rademacher complexity

Sirio Legramanti, Daniele Durante, Pierre Alquier

There has been increasing interest on summary-free solutions for approximate Bayesian computation (ABC) which replace distances among summaries with discrepancies between the empir…

User-friendly introduction to PAC-Bayes bounds

Pierre Alquier

Aggregated predictors are obtained by making a set of basic predictors vote according to some weights, that is, to some probability distribution. Randomized predictors are obtained…
