- Examples: Classifying emails as spam, predicting property prices.
- Popular algorithms: Linear Regression, Decision Trees, Support Vector Machines (SVM).
- Unsupervised Learning
- Definition: The model identifies patterns without labeled data.
- Examples: Customer segmentation, anomaly detection in financial transactions.
- Popular algorithms: K-means, Principal Component Analysis (PCA), Autoencoder Neural Networks.
- Reinforcement Learning
- Definition: The model makes decisions in testing environments, receiving rewards or punishments.
