So excited to be organising this. Don't forget to register if you'd like to attend! We want to bring together people from different disciplines, so if your background is ML without the Ag, or vice versa, but you're interested in learning a bit about the other side - join us in Leipzig (or online)

📢 The 2nd AgML Workshop will be held at @ufz.de Leipzig from November 3–5th! Let's bring together researchers and practitioners in agriculture and machine learning to share knowledge & create open benchmark datasets and model evaluation protocols. Register by July 31: events.hifis.net/e/agml2025

📢 Tomorrow (27th May) at 16:00 CET, join our next online seminar on knowledge-guided machine learning for crop growth modelling! We will be hearing from Jingye Han, a researcher at Wageningen University. Open to all - get in touch for the Zoom link or join the AgML mailing list.
Knowledge-guided machine learning for crop growth modelling

The process-based crop modeling paradigm originated in the 1960s. Despite their widespread use, crop models are constrained by fixed representations of underlying processes and the difficulty of parameter estimation. Moreover, improvements to these models can typically only be made by a small group of experts, leading to inefficiencies. Data-driven approaches offer the potential to become the next-generation modeling paradigm for crops, enabling greater use of data while reducing reliance on manual effort. This talk will explore data-driven crop growth modeling, with an emphasis on how to incorporate domain knowledge to address overfitting issues caused by sparse data, and will offer perspectives on the future development of data-driven crop models.

Looked at the report to see how they evaluated model performance and what a surprise - the reported accuracy metrics are based on randomly sampled datapoints. Spatial data is not i.i.d., and model evaluation is the hardest part of any ML project (but not as fun as trying a dozen model architectures)

🔥🌍 In a new paper led by Sifang Feng, we find a growing human-induced climate change fingerprint in weekly regional fire extremes. 📈 On average, climate change was responsible for a fraction equal to 8 ± 4% of the predicted probability of more than 700 fire extremes worldwide between 2002 and 2015.
