an illustrated diagram for the section "Fundamentals of Machine Learning." The diagram should visually represent the core concepts of machine learning, including supervised, unsupervised, and reinforcement learning. Detail the breakdown of algorithms, feature selection, model training, and evaluation metrics. Highlight how these concepts apply to cybersecurity, using distinct visual elements like flowcharts or mind maps. Incorporate icons and annotations for clarity, illustrating the connections between different machine learning processes and their implications in cybersecurity. The style should be educational and engaging, making complex information accessible and clear.
