Objectives
- Pruning rules can be extracted from expert workers’ demonstrations and explanations.
- Modern cross-domain segmentation models trained with simulated tree images will generalize to the real orchard, reducing the time and resources required for data collection and annotation.
- Hybrid control combining force sensing and eye-in-hand visual feedback from 2D images leads to robust, accurate branch cutting.
Hypotheses
- Develop machine learning models for grape cold hardiness prediction and compare those to existing models.
- Develop and evaluate multi-task learning methods for cold hardiness of different grape cultivars.
- Adapt models developed for grapes to predict sweet cherry cold-hardiness and bud break timing.
- Develop transfer learning methods that can leverage phenology data when cold hardiness training data is not available.
- Porting relevant beta models on AgWeatherNet for grower decision support and testing by a selected set of users.
