Profitons de ce 1er mai pour réfléchir à la valeur travail. A l'ère de l'IA, à l'ère d'une société qui dépend encore du travail, pour produire, mais aussi payer des cotisations sociales pour que l'ensemble de l'édifice tienne debout, en France pour commencer !

✨Bottom line: open source is the invisible infrastructure, possibly as important if not more than datacenter infrastructure.

Looking forward to speaking on the #OpenSourceAI panel at the sold out EU Open Source Policy Summit by @openforumeurope.org in two weeks. Rather than discussing the definition, we’ll focus on how #openness contributes to European competitiveness—or perhaps, how it might help Europe catch up.

Rather than predictions, here are my professional wishes for 2025—shaped by a year of profound learning, building mission-driven @probabl.ai and data science commons with and around @scikit-learn.org, and engaging with brilliant minds, both enthusiastic and concerned about AI: #openness

I am thrilled to announce that I passed the Scikit-learn Associate Practitioner Certification!

Passing the test was a reminder of how rich scikit-learn is and how fascinating data science can be!

This gives me perspective on what we ought to do with skore.

Bringing structure and recommended practices to Machine Learning projects can be challenging. Even experienced data scientists struggle with it.

That's why we built skore – your companion when modeling with scikit-learn. Check it out and let us know what you think!
