On Friday 3^rd and Saturday 4^th of February 2023, the Institute of Data Science at Maastricht University (IDS) hosted the 4th Women in Data Science (WiDS) Maastricht Datathon Event. The WiDS Maastricht Datathon event included a series of activities including data science tutorials, a 2-day working-together hackathon followed by a pitch session, and networking activities.

Around 40 participants from both academia and industry covered many different backgrounds and career stages. The participants were encouraged to connect and learn from each other, and improve their data science skills by solving a climate data challenge. During the pitch session, participating teams presented their methods, the bias and fairness of their models, and lessons learned in these two days.
