Description
This dataset includes sample data for the United States to run the weakly supervised framework as described in the paper titled A weakly supervised framework for high resolution crop yield forecasts, accessible at
| https://doi.org/10.48550/arXiv.2205.09016 |
The updated paper (including results from the US) is published in Environmental Research Letters:
https://doi.org/10.1088/1748-9326/acf50e
The software implementation of the machine learning baseline is available at: https://github.com/BigDataWUR/MLforCropYieldForecasting/tree/weaksup.
