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
