Introduction to Machine Learning

Introduction

Machine Learning is a subset of artificial intelligence that enables systems to learn and improve from experience without being explicitly programmed.

Definition

Machine Learning is the study of computer algorithms that can improve automatically through experience and by the use of data.

Types

Supervised Learning

Learning from labeled data to make predictions or classifications

Unsupervised Learning

Finding patterns and structures in unlabeled data

Reinforcement Learning

Learning through interaction with an environment

Semi-supervised Learning

Learning from both labeled and unlabeled data

Use Cases

• Image and speech recognition
• Natural language processing
• Recommendation systems
• Fraud detection
• Autonomous vehicles

Implementation

Machine learning models are implemented using various algorithms and frameworks, with popular choices including scikit-learn, TensorFlow, and PyTorch.

Relationships

Statistics

ML heavily relies on statistical concepts and methods
