What is Artificial Intelligence?

Artificial Intelligence or "AI" is the ability of machines to mimic human intelligence. It is a branch of computer science that focuses on the development of algorithms and software that can act more like a human than a computer. AI is used for a variety of tasks, such as recognizing patterns, learning from experience, understanding natural language, and making decisions based on large amounts of data.

AI has become increasingly important in the past year, with applications ranging from interactive chatbots to autonomous (self-driving) cars. AI can also be used to automate mundane tasks, streamline business processes, and offer personalized services.

What is AI used for exactly?

AI encompasses a very broad topic but the core components are usually split into the different disciplines outlined below. There are many companies researching AI (including IBM, Microsoft, Google, META, Amazon) each with their own focus and future intended use. Mostly, though, the goal of AI is to make: human lives easier, business operate at a higher level and to keep us entertained.

The top AI areas of focus:

Machine Learning: Machine learning is a form of artificial intelligence that enables computers to learn from data, identify patterns and make decisions with minimal human intervention. It uses algorithms to analyze data and make predictions or decisions based on its findings. Machine learning can be applied to a variety of tasks, from predicting consumer behavior to recognizing objects in images.
Natural Language Processing: Natural language processing (NLP) is a branch of AI that focuses on understanding and processing human languages. It enables computers to interpret and understand natural language inputs, such as spoken words and written text. NLP can be used in applications such as speech recognition, machine translation, sentiment analysis, question answering and text summarization.
Robotics: Robotics is a field of engineering that focuses on the design and development of robots. Robots are machines that can sense their environment, process information and act autonomously or semi-autonomously in order to complete tasks. They can be used in a wide range of applications, from assembly line production to search and rescue operations.
Computer Vision: Computer vision is a subfield of AI that focuses on enabling computers to "see" and interpret the world. It involves the use of algorithms to identify and classify objects in images or videos. Computer vision can be used in applications such as facial recognition, object recognition, image segmentation and autonomous vehicles.
Expert Systems: Expert systems are AI-based computer programs that are designed to emulate the decision-making processes of a human expert. They use knowledge-based systems, which are collections of facts and rules, to solve complex problems. Expert systems are used in various applications, such as medical diagnosis, financial analysis and legal advice.

Neural Networks: Neural networks are computer systems that are modeled after the human brain and nervous system. They use interconnected layers of artificial neurons to process inputs and generate outputs. Neural networks are used in applications such as image recognition, speech recognition and autonomous vehicles.
Deep Learning: Deep learning is a subset of machine learning that is based on artificial neural networks. It uses multiple layers of artificial neurons to process data and generate outputs. Deep learning can be used in applications such as computer vision, natural language processing and automated speech recognition.
Reinforcement Learning: Reinforcement learning is a type of machine learning that enables agents to learn from their environment through trial and error. It uses rewards or punishments to guide the agent’s behavior and adjust its strategy in order to maximize its rewards. Reinforcement learning can be used in applications such as robotics, game playing and autonomous vehicles.
Automated Planning and Scheduling: Automated planning and scheduling is a branch of AI that focuses on using algorithms to solve complex planning and scheduling problems. It enables computers to generate plans and schedules that are optimal or near-optimal in terms of cost, time and resources. Automated planning and scheduling can be used in applications such as supply chain management, job shop scheduling and robotics.
Knowledge Representation and Reasoning: Knowledge representation and reasoning is a branch of AI that focuses on representing knowledge in a form that can be understood and used by computers. It involves the use of formal languages, such as first-order logic, to represent facts and rules. Knowledge representation and reasoning can be used in applications such as automated reasoning, natural language processing and intelligent agents.

The future of AI

Artificial Intelligence is becoming increasingly powerful and is expected to have a major impact on our lives in the coming years. AI is already being used in a variety of different applications, such as driverless cars, medical diagnostics, personal assistants, and robotics. In the future, AI is expected to become even more capable and automated, allowing it to take on more complex tasks. This could lead to higher levels of personalization in services and products, as well as enabling people to access more accurate and timely advice. AI could also create new job opportunities, as it is expected to automate many of the mundane tasks that people currently do.

Finally, AI could potentially help to reduce the risk of accidents and catastrophes (autonomous cars and aircraft) as it is capable of analyzing large data sets very quickly and spotting patterns, objects and trends that many humans may miss.
