Artificial Intelligence (AI): What it is and why it matters

Artificial Intelligence (AI) is changing and improving how we live, work, and interact with the world.

At its core, AI is a technology that makes it possible for computers and machines to simulate how humans learn and interact. With AI, software systems are able to tackle tasks that range from understanding languages to recognising patterns and making decisions. As more industries start utilising AI for various tasks, it's becoming part of everyday life. It influences everything from how we shop to how we get medical advice.

In this article, we'll break down the basics of AI, explaining what it is, and then explore the different types of AI.

What is Artificial Intelligence (AI)?

What is Artificial Intelligence (AI)?

Artificial intelligence (AI) is the simulation of human intelligence in machines that are programmed to think and behave like humans. Machine learning, natural language processing, and computer vision are some of the technologies it covers. AI enables machines to learn from experience, adapt to new inputs, and do activities that would normally require human intellect, such as problem solving, language comprehension, and pattern recognition.

AI aims to create technology that can function autonomously and enhance its capabilities by learning from experiences, much like a human does when acquiring a new skill. For instance, consider your smartphone's virtual assistant. It responds to your voice commands, learns your preferences, anticipates your needs, and can even converse. These things are a testament to AI's capabilities.

How Artificial Intelligence Works

The process behind AI is fascinating and involves teaching computers to learn from training data. This learning process allows AI systems to improve their performance over time, becoming more efficient at handling tasks. To achieve this, AI utilises several technologies and approaches, including machine learning, deep learning, and deep neural networks. Machine learning empowers computers to learn from and make predictions based on data.

In contrast, deep learning, a subset of machine learning, uses layers of algorithms called artificial neural networks to make decisions. Neural networks are inspired by the structure of a human brain, enabling machines to recognise patterns and characteristics in the data fed. AI's ability to adapt and perform tasks requiring human intelligence makes it remarkable. It includes understanding human language through natural language processing, recognising objects or faces, and making decisions based on complex data analyses.

The goal isn't just to automate routine tasks but to develop systems that can think and act with a degree of autonomy comparable to a human. As AI continues to evolve, it opens up new possibilities for solving problems and delivering solutions in ways that were once considered the realm of science fiction.

Different Types of AI

Different Types of AI

When learning about artificial intelligence, it's crucial to understand that not all AI systems are created equal. The landscape of AI is diverse, hosting different intelligence levels from the highly specialised to the ambitiously comprehensive. This differentiation leads us to categorise AI into two primary types: weak AI and strong AI.

Weak AI

Weak AI, also fondly known as narrow AI, is the most commonly encountered form in our daily lives. Its operations are limited to performing specific tasks with remarkable efficiency and accuracy. 

For instance, when you ask Siri for the weather forecast or rely on Alexa to play your favourite tune, you interact with weak AI. These systems excel within their predefined domains but cannot perform beyond their programmed capabilities.

Strong AI

Conversely, strong AI or artificial general intelligence (AGI) represents the vision of creating machines endowed with the full spectrum of human cognitive abilities. The goal here is more advanced and complex. Developers want to engineer an AI that can apply intelligence across various tasks, learn from new experiences, understand complex concepts, and exhibit problem-solving skills akin to human beings.

While this level of AI sophistication remains mainly within the theoretical and research domains, technological advancements, such as deep learning and a neural network, are inching us closer to this futuristic vision. Currently, no perfect examples of strong AI exist, as it is primarily a concept being explored and developed in scientific research. However, various research projects, such as Google's DeepMind and IBM's Watson, are making significant strides towards creating AGI.

Why AI Matters Now More Than Ever
