UNIT 4 – PHYSICAL WORLD


Types of AI There are two types of AI technology currently in use:


AI type Reactive Explanation


Reacts to simple problems based on observation


Limited memory


Makes decisions based on learned information and stored data


Examples


• Streaming services make recommendations based on what a user has already watched or listened to.


• Spam filters recognise suspicious email addresses. • Robot vacuum cleaners recognise and avoid obstacles.


• Self-driving cars monitor conditions and make decisions based on the best outcome to avoid collisions.


• Search engines adapt results based on previous searches and even common spelling mistakes.


• Intelligent virtual assistants (also known as chatbots) help customers based on the outcomes of past queries.

4. Which type of AI do you think is most ‘human-like’? Explain your answer. 5. Would you like to travel in a self-driving car? Why or why not?


Scientific impact of AI


Developments in artificial intelligence allow scientists to: • analyse massive amounts of data • predict outcomes more accurately • reduce error

6. Research one way AI is being used in any of the following scientific fields: a. biology


b. chemistry c. physics d. astronomy Eureka


Scientists have not yet developed AI that is aware of its own existence and has the ability to feel emotions. The development of such AI is thought to be very far in the future, if at all possible. Despite this, AI is most commonly depicted in this way in films such as Wall-E and Avengers: Age of Ultron.
