How does AI work and is it always right?
EVERYONE seems to be talking about how AI is going to change the world – but what on earth is it?
Technology has been evolving rapidly over the past few months, prompting many to brush up on their knowledge of it.
What is AI?
AI stands for artificial intelligence and makes computers act more “human”.
This includes the ability to hold conversations with people – both casual and intellectually challenging.
Computer scientist John McCarthy, one of the originators of the AI concept, put it this way: “It is the science and engineering for making intelligent machines, especially intelligent computer programs.
“It’s related to the similar task of using computers to understand human intelligence, but AI doesn’t have to be limited to methods that are biologically observable.”
How does AI work?
AI can analyze huge amounts of data at speeds impossible for the human mind.
It can be trained as well as learned.
The basis of AI is machine learning, which relies on models using mathematics, statistics and classification methods.
Developers will teach the computer to understand classification methods, which means the AI can recognize patterns and form groups of certain things.
A machine with built-in AI can learn from its interactions with human users, individual data sets, and the internet.
All it has to do first is understand the learning process, and the developers will program that understanding into the machine.
Is AI always right?
Today, AI can help doctors diagnose patients, pilots fly commercial airliners, and city planners predict traffic.
While it can do these things well, that doesn’t mean it’s always right.
An AI bot is typically smarter than the average human, but it’s designed by humans – which means it can be prone to human error and bias.
AI Bias can see a computer making decisions based on training data that can reflect human biases such as social inequalities.
In 2018, Amazon stopped using a recruitment algorithm when it discovered that the AI’s preferred applications were based on words like “executed” or “captured” — which were more common on men’s resumes.
What four types of AI are there?
- Reactive AI – the most basic form of AI that lacks the ability to form memories or use past experiences to make current decisions.
- Limited memory AI – a type of AI commonly found in self-driving cars that allows machines to look into the past to understand, for example, lane markings.
- Theory of Mind AI – The AI understands that humans, creatures and objects in the world can have thoughts and emotions that the machine must adapt its behavior to.
- Confident AI – the final step in AI, where developers understand consciousness to the point where they can program a machine to run on it.
Does Siri count as AI?
While it gives the impression of being artificially intelligent, Siri is a digital voice assistant.
Siri cannot learn from his past choices and use those memories to make new choices.
Instead, the Apple Assistant can provide a number of pre-installed options to best help users with their queries.
