Our third Ocean retreat will take place at Durham, England!

09.2025 Acceleration at Warwick

The acceleration week brought together early-career OCEAN researchers (PhD students and postdocs) to brainstorm and kick-start a project. The aim: draft early outlines of research articles, push forward the OCEAN agenda, and spark new connections across the community.

07.2025 Second Ocean summer retreat at the Parisanté Campus in Paris

Ocean has had its second Summer retreat from the 21st to the 25th of July, 2024 at the Parisanté Campus, Paris, where a part of the team resides. It brought together Ocean researchers and students who presented on-going work and explored possible collaborations in an informal and relaxed way.

05.2025 From Matching to Market. A Tale of Mathematics, Economics and Computer Science.

This conference was co-organized by OCEAN to bring together researchers in mathematics, computer science, and economics with a shared interest in matching problems and market design. Talks spanned a wide range of topics—from specific markets to general models, theory, empirical work, and more.

02.2025 Second privacy meeting at Les Houches, France

Ocean held its second privacy meeting at Les Houches, in the French Alps. This internal workshop gathered confidentiality and statistical experts to study privacy, especially for Bayesian inference and MCMC computation.

07.2024 First Ocean summer retreat at the Ca’ Foscari University of Venice

Ocean has held its first Summer retreat from the 7th to the 12th of July, 2024 at the Ca’ Foscari University of Venice!  This event brought together Ocean researchers and students to make waves in the world of science and innovation! Including talks, working sessions to fuel collaboration, and short courses exploring the intersection of machine learning and Economics.

07.07.2024 ISBA-Cini : Artificial intelligence, data sharing and regulation

Ocean co-organized with ISBA the conference « Artificial Intelligence, Data Sharing, and Regulation » at Venice. The focus was on the most recent advances and the future perspectives of research in artificial intelligence and statistics, putting particular emphasis on ethical and regulatory issues. Christian Robert, Stéphanie Allassonnière and Michael Jordan spoke on Statistics and Machine Learning as well as their integration in the European Market.

03.2024 Seminar at the Houches

In March 2024, Ocean held its first internal seminar in the Houches, France. This meeting saw some Ocean researchers and invited experts (Arnoldo Frigessi, Steve MacEachern, Sylvia Richardson, Judith Rousseau) gather with short presentations and joint work sessions on open problems and potential collaborations.

The scientific program was focused on two core research axes of Ocean: differential privacy in collaborative models and Bayesian inference and sampling.

03.2024 Launch of the Ocean seminar

The first session of the Ocean seminar was held on the 1st of March! This seminar aims at gathering all Ocean researchers and students once a month to foster collaboration and discuss advances about ongoing research. Antoine Scheid inaugurate dthis seminar by presenting his work about incentives in a principal-agent bandit framework.

02.2024 Warwick wired to Paris

Stanislas Duché and Christian Robert spent a week at Warwick University to collaborate with Gareth Roberts‘ team about privacy-related projects. This exchange was ponctuated by very interesting discussions with Gareth Roberts,, Ritabrata Dutto, Massimiliano Tamborini, and their students, and a presentation of Stanislas to Warwick’s PhD reading group.

01.2024 From Warwick to All-About-That-Bayes

On the 23th of January 2024 at PariSanté Campus, Ritabrata Dutta (Warwick University) introduced « Bayesian Model Averaging with exact inference of likelihood- free Scoring Rule Posteriors » at the All-About-That-Bayes seminar. This seminar, held at OCEAN’s PariSanté campus offices, brought together teams from Warwick and Dauphine as well as Paris statisticians.

12.2023 Ocean was at CIRM!

Last week, the CIRM in Marseille hosted the seminar ‘From Matching to Markets: a tale of Mathematics‘, with the aim of gathering researchers from the fields of mathematics, computer science, and economics to study of matching problems and the design of their markets.
Ocean was well represented, since Vianney Perchet was a member of the Organizing Committee and Michael I. Jordan part of the Scientific Committee. Michael gave a talk about Statistical Contract Theory while Etienne Boursier took the floor to present an overview on Multiplayer Bandits. We learnt a lot there and had fun, thank you to everyone for this event!
