What is AI and Machine Learning?
Artificial Intelligence (AI)
Think of AI as teaching computers to think and make decisions like humans. It's the broader concept of machines being able to carry out tasks in a way that we would consider "smart."
Real-world example: When Siri understands your voice command or when your email automatically filters spam, that's AI at work!
Machine Learning (ML)
ML is a subset of AI where computers learn patterns from data without being explicitly programmed for every scenario. It's like teaching a computer to recognize patterns and make predictions.
Real-world example: Netflix recommending shows you might like based on what you've watched before – that's machine learning in action!
Simple Analogy: If AI is like teaching a child to be smart, then ML is like showing them thousands of examples so they can learn patterns and make smart guesses on their own!
