What is reproducibility and why do we need to care about it in machine learning research? What are the best practices for sharing machine learning models in your research? Join us for this one day event focused on machine learning and reproducibility. It is possible to obtain 1 ECTS / Certificate by actively participating to the event and doing some extra homework.

Registration is mandatory, so that we can ensure enough seats for everyone (and free snacks!).

Where

LUMI AI Factory Hub, TUAS, 4th Floor, Maarintie 8, Espoo.

Online via zoom (this is also possible but we cannot guarantee the same level of experience as those coming to the in-person event). 

More details will be sent a few days before the event.

Schedule

The event happens on the 20th May 2026. The schedule below is being updated and comes from a previous run of the event.
