Chapter 2: Types of Machine Learning
The chapter introduces the three primary types of machine learning: Supervised Learning, Unsupervised Learning, and Reinforcement Learning. It provides definitions and real-life analogies for each type, explain how machines learn based on examples, and includes simple Python code examples for better understanding. The chapter emphasizes the importance of these learning types in making decisions based on data.

What we have learnt
- Machine learning is divided into three types based on how a machine receives information.
- Supervised learning utilizes labeled data to predict outcomes.
- Unsupervised learning identifies patterns in unlabeled data, while reinforcement learning is based on trial and error with rewards and penalties.
Key Concepts
- -- Supervised Learning
- A type of machine learning where the model learns from labeled input data to predict output.
- -- Unsupervised Learning
- A type of machine learning where the model identifies patterns in unlabeled data without predefined outcomes.
- -- Reinforcement Learning
- A learning method where an AI agent learns by taking actions in an environment, receiving rewards or penalties, and optimizing its strategy over time.
- -- Regression
- A subtype of supervised learning focused on predicting continuous numerical values.
- -- Classification
- A subtype of supervised learning that categorizes data into distinct classes.
