Machine Learning algorithms are broadly classified into the following categories:

1. Supervised Learning Algorithms

  • Trained using labeled data

  • Examples:

    • Linear Regression

    • Logistic Regression

    • Decision Tree

    • Random Forest

    • Support Vector Machine (SVM)

2. Unsupervised Learning Algorithms

  • Trained using unlabeled data

  • Examples:

    • K-Means Clustering

    • Hierarchical Clustering

    • Apriori Algorithm

    • PCA

3. Semi-Supervised Learning Algorithms

  • Use both labeled and unlabeled data

  • Example: Image classification with limited labels

4. Reinforcement Learning Algorithms

  • Learn through rewards and penalties

  • Examples:

    • Q-Learning

    • Deep Q Network (DQN)

    • Policy Gradient

Summary

  • Supervised Learning → Uses labeled data

  • Unsupervised Learning → Finds hidden patterns

  • Reinforcement Learning → Learns by experience
