AI vs machine learning vs deep learning
AI: the big idea
AI is any computer program that does something we think of as smart. Playing chess, understanding speech and answering questions are all AI.
Machine learning: learning from examples
Old programs follow rules a person wrote. With machine learning, nobody writes the rules. The computer looks at lots of examples and works out the rules itself, like a child who learns what a dog is by seeing many dogs.
Deep learning: learning in layers
Deep learning uses a network with many layers. Each layer picks out something simple, and the next layer builds on it. It is what makes photo recognition and chatbots work well.
Key takeaways
- AI is the goal. Machine learning is the way. Deep learning is the strongest way today.
- Machine learning learns from examples instead of fixed rules.
- Chatbots like ChatGPT use deep learning.
Quick questions
Is machine learning the same as AI?
No. It is one way of building AI. Some older AI just followed rules.
Is ChatGPT deep learning?
Yes. It is a deep learning model trained on a huge amount of text.
Do I need maths to understand this?
No. The ideas make sense without any maths.
