Max Zimmer
My research interests focus on Deep Learning, Efficient ML, Optimization and Sustainable AI. Specifically, I work on enhancing the efficiency of large Neural Networks through sparsity, pruning, quantization, and low-rank optimization. Additionally, I am interested in Federated Learning, Interpretability & Fairness, as well as applying ML to solve pure mathematics problems. Recently, I started using Deep Learning methods on satellite imagery to create high-resolution surface maps of the globe, allowing to track climate-relevant metrics such as above ground biomass.

🔬 Projects
Preserving global vegetation is crucial for addressing and mitigating climate change. Accurate, up-to-date forest health data is essential. AI4Forest aims to develop advanced AI methods to monitor forests using satellite imagery, including radar and optical data. The project will create scalable techniques for detailed, high-resolution maps of the globe, e.g., to monitor canopy height, biomass, and to track forest disturbances.
SynLab researches mathematical generalization of application-specific advances achieved in the Gas-, Rail– and MedLab of the research campus MODAL. The focus is on exact methods for solving a broad class of discrete-continuous optimization problems. This requires advanced techniques for structure recognition, consideration of nonlinear restrictions from practice, and the efficient implementation of mathematical algorithms on modern computer architectures. The results are bundled in a professional software package and complemented by a range of high-performance methods for specific applications with a high degree of innovation.
