🚀 Machine Learning — 4 Core Approaches (Quick Guide)
🔵 Supervised Learning
Labeled data → Predict outcomes
💡 Use: Classification, regression
🟢 Unsupervised Learning
No labels → Find hidden patterns
💡 Use: Clustering, segmentation
🟡 Semi-Supervised Learning
Few labels + lots of unlabeled data
💡 Use: When labeling is expensive
🟠 Reinforcement Learning
Learn via rewards & penalties
💡 Use: Decision-making, game AI
💡 Bottom line:
👉 Data defines the method
👉 Problem defines the approach
📌 Save & revisit
