Title: Machine Learning for Image-based Plant Phenotyping
Abstract: Deep learning approaches have been successfully deployed for a diverse array of image-based plant phenotyping applications. However, successful deployment of supervised deep learning models requires large amount of labeled data, which is a significant challenge in plant science (and most biological) domains due to the inherent complexity. Specifically, collection and annotation of relevant data is a costly, laborious, time consuming and might need domain expertise. In this talk, I will summarize about the usefulness of domain adaptation, active learning, and local explanation techniques for plant phenotyping applications. I will focus on how these methods can be used to overcome the distribution shift, data annotation and interpretability challenges in applying deep learning models to Maize and Soybean phenotyping tasks.
