The objective is to assess how different algorithmic approaches perform in detecting forest loss based on spectral and vegetation index signals derived from multi-temporal optical imagery.

Key evaluation metrics were used to characterize the strengths and limitations of each approach. The results show that, under the right conditions, well-optimized traditional machine learning models can achieve deforestation detection performance comparable to that of deep learning techniques. This highlights the importance of careful feature engineering and the quality of ground truth labels. While recurrent neural networks excel in capturing complex temporal dynamics, they come with substantial computational costs and implementation complexity. In contrast, classical models such as ensemble methods or linear classifiers offer competitive performance when paired with informative input representations and are better suited for scalable or resource-constrained monitoring systems.
