We have an event every week these days! 🍕 After the machine learning challenge, we organized a sprint with Unaite to onboard students to open source. Open source is a great way to showcase their skills, as would a personal project!

🖌️ There is that plot provided by skore that you like. It quickly gives an idea of the performances. You would like to see the underlying numbers to investigate further. 🔍 That’s why we created the Displays, that can either return a frame, or a plot. 📚 eu1.hubs.ly/H0lfgz60

What is the difference between good and bad data scientists? Good ones know the data they work with. Perfectly understanding the data can be time-consuming. Yet, some basic analysis can pave the way for high-value insights. Now in skore’s release 0.10, with a data accessor!

🚀 Save time on ML evaluations with skore! 🚀 No more recomputing predictions for each metric. Skore caches predictions, enabling instant metric calculations and fast plots. Check out this example for more information: eu1.hubs.ly/H0md0-f0

Cristina Caffarra I agree - that's why I think a Eurostack initiative, combined with muscular interop (including adversarial interop) from the DMA and DMA-like future rules, alongside rescinding anti-circumvention law, is the way out. The DMA is necessary, but grossly insufficient.
