Quick ones on AI & machine learning.

(a)A program that plays chess brilliantly but can do nothing else is an example of?
  1. Artificial general intelligence
  2. Narrow AI
  3. A Turing machine
(b)In machine learning, what is training data?
  1. The final results the model shows to users
  2. The source code the model is written in
  3. Example data a model learns patterns from
(c)What does generative AI do?
  1. Creates new content such as text or images

What is supervised learning?

  1. A teacher watching over students as they use AI tools in class
  2. A model that finds its own groups in data with no labels
  3. Training a model on examples labelled with the right answers
Show the answer

Training a model on examples labelled with the right answers

e.g. thousands of photos labelled cat or dog. The model learns patterns linking inputs to labels, then predicts labels for new photos.

More AI & machine learning questions

AI & machine learning, 2 marks

AI that is good at one task only, like recognising faces, is called…

  1. General AI
  2. Strong AI
  3. Narrow AI
Show the answer

Narrow AI

All AI in use today is narrow, e.g. spam filters and voice assistants. General AI that can do any task a human can does not exist yet.

AI & machine learning, 2 marks

In machine learning, a program gets better by…

  1. Running on a bigger screen
  2. Learning from examples in data
  3. Being rewritten by hand each day
Show the answer

Learning from examples in data

e.g. shown thousands of labelled photos of cats and dogs, a model learns patterns so it can label new photos. More good data usually means better results.

AI & machine learning, 2 marks

AI that creates new text or images from a prompt is called…

  1. Generative AI
  2. A search engine
  3. A spreadsheet
Show the answer

Generative AI

Generative AI (chatbots, image generators) produces new content. It can make things up, so its output should always be checked.
