We built a global dataset of 6.3M remote sensing samples covering 21,001 tree species with rich taxonomic labels. We developed GeoTreeCLIP, a CLIP-based vision-language foundation model for joint understanding of remote sensing imagery and species descriptions. Our model achieved strong zero-shot and few-shot performance, setting new benchmarks for multimodal tree species classification. All data and code are open-sourced to support the geospatial AI community.

We designed ForestFormer, a dual-branch neural network with spectral-spatial attention. Our model achieved 84% accuracy across 8 dominant tree species using Sentinel-2 time series data. We generated a comprehensive, high-resolution tree species distribution map for Germany and provided forest management insights on species resistance and biodiversity levels. Code and pre-trained models are released to support open research and applications.

MPTSNet: Integrating Multiscale Periodic Local Patterns and Global Dependencies for Multivariate Time Series Classification
Yang Mu*, Muhammad Shahzad, and Xiao Xiang Zhu
In Proceedings of the AAAI Conference on Artificial Intelligence, 2025
We designed a Multiscale Periodic Time Series Network for multi-periodicity analysis. Our approach combined CNN-based local pattern extraction with attention mechanisms for global dependency modeling. MPTSNet outperformed 21 existing baseline methods in extensive benchmark datasets. We released codes to support reproducible research and open-source applications.
