This document discusses the use of machine learning algorithms for crop mapping and monitoring crop phenology. It begins with an introduction to machine learning in agriculture, noting its use in predicting crop yields and quality. It then describes the main types of machine learning: supervised, unsupervised, and reinforcement learning. The document outlines how each type works. It also discusses how machine learning is used for crop mapping, monitoring growth cycles, and detecting diseases or weeds. Advantages include digital farming, yield prediction, and livestock management. Challenges are also noted, such as needing large clean datasets to train algorithms effectively.
