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
