Skrub 0.2.0: tabular learning made easy

We just released skrub 0.2.0. This release markedly simplifies learning on complex dataframes.

model = tabular_learner(‘classifier’)

Simple, yet solid default baseline

The highlight of the release is the tabular_learner function, which facilitates creating pipelines that readily perform machine learning on dataframes, adding preprocessing to a scikit-learn compatible learner …

Do AIs reason or recite?

Despite their apparent intelligence, conversational artificial intelligences often lack logic. The debate rages on: do they reason or do they recite snatches of text memorized on the Internet?


This post was originally published in French as part of my scientific chronicle in Les Echos.

Conversational AI, or large language …

Promoting open-source, from inria to :probabl.


Open-source efforts around scikit-learn at Inria are spinning off to a new enterprise, Probabl, in charge of sustainable development of a data-science commons.

People underestimate how impactful Scikit-learn continues to be


François Chollet rightfully said that people often underestimate the impact of scikit-learn. I give here a few illustrations to back his claim.

A few days ago, François Chollet (the creator of Keras, the library that that democratized deep learning) posted:

Tweet from François Chollet: "People underestimate how impactful scikit-learn continues to be"

Indeed, scikit-learn continues to be the most popular machine …

2022, a new scientific adventure: machine learning for health and social sciences

A retrospective on last year (2022): I embarked on a new scientific adventure, assembling a team focused on developing machine learning for health and social science. The team has existed for almost a year, and the vision is nice shaping up. Let me share with you illustrations of where we …

My Mayavi story: discovering open source communities

The Mayavi Python software, and my personal history: A thread on Python and scipy ecosystems, building open source codebase, and meeting really cool and friendly people

I am writing today as a goodbye to the project: I used to be one of the core contributors and maintainers but have been …

2021 highlight: Decoding brain activity to new cognitive paradigms

Broad decoding models that can specialize to discriminate closely-related mental process with limited data


Decoding models can help isolating which mental processes are implied by the activation of given brain structures. But to support a broad conclusion, they must be trained on many studies, a difficult problem given …

Hiring an engineer and post-doc to simplify data science on dirty data


Join us to work on reinventing data-science practices and tools to produce robust analysis with less data curation.

It is well known that data cleaning and preparation are a heavy burden to the data scientist.

Dirty data research

In the dirty data project, we have been conducting machine-learning research …

Hiring someone to develop scikit-learn community and industry partners


With the growth of scikit-learn and the wider PyData ecosystem, we want to recruit in the Inria scikit-learn team for a new role. Departing from our usual focus on excellence in algorithms, statistics, or code, we want to add to the team someone with some technical understanding, but an …
