- 1What AI is (and isn't)Artificial intelligence (AI) is when computers do tasks that usually need human thinking, like recognising faces or understanding speech. Many AI systems learn from examples instead of only following rules written by people.Not triedNotesQuiz
- 2Data: what AI learns fromData is information, such as numbers, words, pictures and sounds. AI needs lots of data to learn, and the quality of the data decides how well it works.Not triedNotesQuiz
- 3Finding patternsA pattern is something that repeats or happens in a regular way. AI is very good at finding patterns in large amounts of data and using them to make predictions.Not triedNotesQuiz
- 4Machine learning: learning from examplesMachine learning is a way of making AI where the computer learns from many examples instead of being given every rule. Examples often have labels (the right answers) and features (the details the computer looks at).Not triedNotesQuiz
- 5Training and testingAn AI model is trained on one set of examples and then tested on new examples it has never seen. Testing shows whether it really learned the pattern or just remembered the answers.Not triedNotesQuiz
- 6Recognising pictures and speechAI can recognise what is in a picture and turn spoken words into text. It does this by turning pictures and sounds into numbers and finding patterns it learned from many examples.Not triedNotesQuiz
- 7Chatbots and recommendationsChatbots answer in words by predicting what should come next. Recommendation systems suggest videos, songs or products by predicting what you might like from what you and similar people chose before.Not triedNotesQuiz
- 8Bias and fairnessAI learns from data collected by people, so if the data is unbalanced or unfair, the AI can be unfair too. This is called bias. People must check AI and fix bias so that it treats everyone fairly.Not triedNotesQuiz
- 9Using AI safely and wiselyAI tools can help you learn, but you need to protect your privacy, check facts and do your own work. AI can make things up, so reliable sources and a trusted adult help you stay safe.Not triedNotesQuiz
