Far from being the stuff of science-fiction, artificial intelligence, or AI, is becoming an increasingly common sight in today's world.

Combining the latest powerful software with top-of-the-range hardware, AI tools are being used to transform many areas of everyday life, from healthcare to traffic problems.

But what is AI, and how is it being used today? Here is our guide to everything you need to know, and some of the most innovative and interesting use cases around today.

What is AI?

For years, it was thought that computers would never be more powerful than the human brain, but as development has accelerated in modern times, this has proven to be not the case.

AI as a concept refers to computing hardware being able to essentially think for itself, and make decisions based on the data it is being fed. AI systems are often hugely complex and powerful, with the ability to process unfathomable depths of information in an extremely quick time in order to come to an effective conclusion.

Thanks to detailed algorithms, AI systems are now able to perform mammoth computing tasks much faster and more efficiently than human minds, helping making big strides in research and development areas around the world.

Some of the most notable real-world applications of AI are IBM's Watson, which is being used to power research in a huge range of fields,  with Microsoft's Azure Machine Learning and TensorFlow also making headlines around the world.

But AI-powered smart assistants are becoming a common presence on mobile devices too, with the likes of Siri, Cortana and Alexa all being welcomed into many people's lives.

There seems no limit to the applications of AI technologies, and perhaps the most exciting aspect of the ecosystem is that there's no telling where it can go next, and what problems it may ultimately be able to solve.
