Introduction

Machine learning is a branch of artificial intelligence (AI) that focuses on building systems that learn from data. These systems can perform tasks without being explicitly programmed. Machine learning is widely used in various fields, including healthcare, finance, and e-commerce.

Basic Concepts

Before diving into the different types of machine learning, let's first understand some basic concepts:

  • Data: The raw information used to train machine learning models.
  • Features: The characteristics or attributes of the data.
  • Labels: The target variable or the output that the model should predict.

Supervised Learning

Supervised learning is a type of machine learning where the model is trained on labeled data. The goal is to learn a mapping from the input features to the correct output labels.

Common Algorithms

  • Linear Regression
  • Logistic Regression
  • Support Vector Machines (SVM)
  • Decision Trees

Unsupervised Learning

Unsupervised learning involves training models on unlabeled data. The goal is to find patterns and relationships in the data without explicit instructions.

Common Algorithms

  • K-Means Clustering
  • Hierarchical Clustering
  • Principal Component Analysis (PCA)
  • Association Rules

Reinforcement Learning

Reinforcement learning is a type of machine learning where an agent learns to make decisions by interacting with an environment. The agent receives rewards or penalties based on its actions.

Common Algorithms

  • Q-Learning
  • Deep Q-Network (DQN)
  • Policy Gradient Methods
