Abstract

In this work, we investigate the application of existing unsupervised domain adaptation (UDA) approaches to the task of transferring knowledge between crop regions having different coffee patterns. Given a geographical region with fully mapped coffee plantations, we observe that this knowledge can be used to train a classifier and to map a new county with no need of samples indicated in the target region. Experimental results show that transferring knowledge via UDA strategies performs better than just applying a classifier trained in a region to predict coffee crops in a new one. However, UDA methods may lead to negative transfer, which may indicate that domains are excessively dissimilar, rendering transfer strategies ineffective. We observe a meaningful complementary contribution between coffee crop data; and a visual behavior suggests the existence of clusters of samples that are more likely to be drawn from a specific data.
