What is AI?
2
You've probably heard a lot about artificial intelligence or AI in the last few years.
3
News and social media has been flooded with stories
4
and reports about AI and there's been a global conversation about the balance between risks and supporting innovation.
5
But once we sweep away some of the complicated words, cliched imagery and science fiction, what is artificial intelligence?
6
The term artificial intelligence can mean a lot of things and there is no single definition that is suitable for every scenario.
7
But one widely accepted meaning is that AI systems are machines
8
that perform tasks that normally require human intelligence and often learn from and use data to do those tasks.
9
The idea of AI has been around for a long time.
10
Discussions around artificial intelligence began in the 1940s and 1950s with the advent of computers
11
and had already entered homes by the end of the 20th century with the AI systems inside automated vacuum cleaners.
12
AI systems follow the rules of an algorithm or a method of data analysis called machine learning to make predictions and decisions.
13
These systems are often used to do tasks that are traditionally thought of as requiring humans.
14
So, what are the different types of artificial intelligence?
15
Here are a few examples.
16
Narrow AI is the type of AI that has been around the longest.
17
It is an artificial intelligence system that has been developed or trained to do one specific task.
18
For example, a fraud detection tool might be trained to look for patterns in a set of financial transactions
19
and flag the need for investigations.
20
General purpose AI involves using large quantities of data to train a system to perform a wide range of tasks.
21
These AI systems can be used to generate content, translate languages or answer queries.
22
They are often referred to as foundation models
23
because they can provide a base system upon which more specific AI applications can be built.
24
You may also have heard of the term Artificial General Intelligence or AGI.
25
This is an idea that computers will soon be able to achieve general intelligence and autonomy, but this is still, as yet, very much theoretical.
26
Has your council started discussions about an AI strategy?
27
What existing processes in your council could benefit from AI support?
28
What training or guidance might you and your team need to work effectively with AI?
29
Watch more of our AI Unpack series to explore answers to some of the most common questions about AI.
30
These videos explain some of the terms and concepts to help you understand how you and your organisation
31
might respond to the opportunities and challenges the AI brings.

O que é a Técnica de Shadowing?
Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
