Artificial Intelligence | 23 May 2023

The year 2022 brought Artificial Intelligence (AI) into the mainstream through widespread familiarity with applications of Generative Pre-Training Transformer (GPT). The most popular application is OpenAI's ChatGPT. The widespread interest and fascination surrounding ChatGPT have contributed to its recognition as a prominent example of AI technology among consumers. However, it represents only a small portion of the ways that AI technology is being used today.

What is AI?

• About:
  • AI is the ability of a computer, or a robot controlled by a computer to do tasks that are usually done by humans because they require human intelligence and discernment.
    • Although there is no AI that can perform the wide variety of tasks an ordinary human can do, some AI can match humans in specific tasks.
• Characteristics & Components:
  • The ideal characteristic of artificial intelligence is its ability to rationalize and take actions that have the best chance of achieving a specific goal. A subset of AI is Machine Learning (ML).
    • Deep Learning (DL) techniques enable this automatic learning through the absorption of huge amounts of unstructured data such as text, images, or video.

What are the Differences Between AI, ML and DL?

• The term AI, coined in the 1950s, refers to the simulation of human intelligence by machines. AI, ML and DL are common terms and are sometimes used interchangeably. But there are distinctions.
  • ML is a subset of AI that involves the development of algorithms that allow computers to learn from data without being explicitly programmed.
    • ML algorithms can analyze data, identify patterns, and make predictions based on the patterns they find.
  • DL is a subset of ML that uses artificial neural networks to learn from data in a way that is similar to how the human brain learns.

What are the Different Categories of AI?

• Artificial intelligence can be divided into two different categories:
  • Weak AI/ Narrow AI: It is a type of AI that is limited to a specific or narrow area. Weak AI simulates human cognition.
    • It has the potential to benefit society by automating time-consuming tasks and by analyzing data in ways that humans sometimes can’t.
    • For example, video games such as chess and personal assistants such as Amazon's Alexa and Apple's Siri.
  • Strong AI: These are systems that carry on tasks considered to be human-like. These tend to be more complex and complicated systems.
    • They are programmed to handle situations in which they may be required to problem-solving without having a person intervene.
    • These kinds of systems can be found in applications like self-driving cars.

What are the Different Types of AI?

• Reactive AI: It uses algorithms to optimize outputs based on a set of inputs. Chess-playing AI, for example, are reactive systems that optimize the best strategy to win the game.
  • Reactive AI tends to be fairly static, unable to learn or adapt to novel situations. Thus, it will produce the same output given identical inputs.
• Limited Memory AI: It can adapt to past experiences or update itself based on new observations or data. Often, the amount of updating is limited, and the length of memory is relatively short.
  • Autonomous vehicles, for example, can read the road and adapt to novel situations, even learning from past experience.
• Theory-of-mind AI: They are fully adaptive and have an extensive ability to learn and retain past experiences. These types of AI include advanced chat-bots that could pass the Turing Test, fooling a person into believing the AI was a human being.
  • A Turing test is a method of inquiry in AI for determining whether or not a computer is capable of thinking like a human being.
• Self-aware AI: As the name suggests, become sentient and aware of their own existence. Still, in the realm of science fiction, some experts believe that an AI will never become conscious or alive.

What is the Difference Between Augmented Intelligence and AI?

• The Difference in Focus: Artificial Intelligence is focused on creating machines that can perform tasks autonomously, without human intervention. On the other hand, Augmented Intelligence is the use of technology to enhance human intelligence, rather than replace it.
  • Augmented Intelligence systems are designed to work alongside humans to improve their ability to perform tasks.
• The Difference in Goal: The goal of AI is to create machines that can perform tasks that require human intelligence, such as decision-making and problem-solving.
  • The goal of Augmented Intelligence, on the other hand, is to enhance human capabilities, by providing them with tools and technologies that can help them make better decisions and solve problems more efficiently.
