Probabl’s get together, in falls 2025
I’m thrilled to announce that I’m stepping up as Probabl’s CSO (Chief Science Officer) to supercharge scikit-learn and its ecosystem, pursuing my dreams of tools that help go from data to impact.
Scikit-learn is central …
AI is everywhere. Can you see it here?

Some highlights about my work in 2025: progress on tabular-learning stands out, a publication on unpacking trade-off and consequences of scale in AI, and of course progress on the open-source data-science and machine learning stack.
As 2026 starts, I’m looking …
At Maïc’s 100th birthday, I asked her “you lived 100 years, what was the most important change for you?”. She mentioned “Internet”. I asked, why was the Internet important to her eyes? Because this is how she kept close contact with her loved ones, sharing travels or discussing everyday …
I have recently been awarded France’s national order of merit, for my career, in science, in open source, and around AI.
The speech that I gave carries messages important to me (French below; it flows better).

TabICL is a state-of-the-art tabular learner [Qu et al 2025]. The key is its very rich prior, that is baked in a pre-trained architecture -a table foundation model-, and leveraged by in-context-learning. Thanks to clever choices, it is fast and scalable, efficient even without a GPU.

Modern AIs acquire new capabilities by combining tools to perform a complex task, controlling them like an agent. Unlike traditional programming, they define the sequences of actions themselves.

I would like to take a brief moment to reflect on what drives me as an academic.
Academia’s root are in creating knowledge and sharing it. We, academics, have a role to play in shaping society. In computer science, we sometimes focus on the creation of technology. Here, creation …
Since 2017, an AI has been defeating the best Go experts, despite the game being particularly challenging. Such “super intelligence” is rare, but it could also emerge in fundamental mathematics.

Is unbiased data important to build health AI? Yes!
Can there be unbiased data? No!
The notion of bias depends on the intended use.
In medicine, we have seen the importance of tuning devices and decisions for the target population. The problem is not …

For me, 2024 was full of back and forth between research, software, and connecting these to society. Here, I lay out some highlights on AI and society, as well as research and software, around tabular AI and language models.
As 2025 starts, I’m looking back on 2024. It …
Improving conversational artificial intelligences or simpler prediction engines involves overcoming biases, that is, going beyond the limits of data. But the notion of bias is subtle, as it depends on the goals.

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?

Foundation models, pretrained and readily usable for many downstream tasks, have changed the way we process text, images, and sound. Can we achieve similar breakthroughs for tables? Here I explain why with “CARTE”, we’ve made significant headway.

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

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