2.3 What is Machine Learning
2.3 What is Machine Learning Machine learning is a branch of artificial intelligence (AI) that teaches computers to learn and make predictions or decisions without being explicitly programmed. It involves training a computer system using data so that it can recognize patterns and make accurate predictions or take actions based on those patterns. Here are a few real-world examples to help illustrate the concept: Spam Detection : Imagine you receive lots of emails every day, and some of them are spam. Machine learning algorithms can be trained to analyse the content, structure, and characteristics of emails to identify patterns commonly found in spam emails. Once trained, the system can automatically classify incoming emails as either spam or not spam, helping you avoid cluttering your inbox with unwanted messages. Voice Assistants: Virtual voice assistants like Siri, Alexa, or Google Assistant rely on machine learning to understand and respond to user commands or queries. These assista
