Working Thesis Title

Tree-Based Classification Methods for Spatial Populations with Biosecurity Applications in New Zealand.

Many countries and regions have their own crop type mapping and biosecurity initiatives, however, New ���سԹ�does not have a specific nationwide crop mapping program solely dedicated to biosecurity. Therefore, the goal of this research is to optimize and fine-tune the tree-based methods to create an accurate and efficient crop mapping program that addresses biosecurity concerns in New ���سԹ�considering the spatial populations.��
