An interesting history of artificial intelligence may be traced back to the 1950s, when the idea was initially proposed. Making computers capable of carrying out tasks that generally need human intelligence was the original aim of artificial intelligence.

Making computers capable of carrying out tasks that generally need human intelligence was the original aim of artificial intelligence.  

John McCarthy, who is generally referred to as the father of AI, first used the term “artificial intelligence” in 1956.

Although there was a lot of buzz surrounding AI in its early years, development remained slow due to a lack of money and computing power. Significant advancements in AI research didn’t occur until the 1980s, when expert systems that could solve problems in particular fields began to appear.

Machine learning algorithms made it possible for machines to learn from data, and they began to gain popularity in the 1990s.  This led to the development of neural networks, which are models that mimic the structure of the human brain.

AI has grown rapidly in the 21st century as a result of developments in deep learning algorithms, large data, and cloud computing. A number of sectors, including healthcare, banking, transportation, and entertainment, are now utilising AI.

Overall, since its start, AI has come a long way, and its development is showing no indications of stopping. With the enormous variety of possible uses for AI, it is probable that this technology will continue to experience significant advancements in the years to come.

Types of AI

Artificial Intelligence (AI) is a broad field with many subfields and applications. AI systems can be broadly classified into four types: 

  1. Reactive machines
  2. Limited memory
  3. Theory of mind, and
  4. Self-aware AI.
    1. Reactive machines 
      The most basic form of artificial intelligence, reactive machines just take into account the situation at hand. These machines lack the capacity to create memories and are unable to use prior experiences to guide their actions. Based only on the programming they have received, they simply respond to the current circumstance. 
      A chess-playing computer software that can assess the board and make moves based on the situation of the game is a typical example of a reactive machine.

    1. Limited memory
      limited memory As the names suggest, artificial intelligence (AI) is able to make decisions based on prior experiences. These machines are able to examine past data, make inferences from it, and utilise that knowledge to forecast what will happen in the future. Artificial intelligence with a limited memory might, for instance, be used in weather forecasting systems that study historical weather trends to determine future weather conditions.

    2. Theory of Mind
      theory of mind is a more developed form of AI and is able to comprehend other people’s emotions and mental states. These computers are capable of recognising and understanding that other beings have feelings, desires, and thoughts, and they can make better use of this understanding when interacting with other people. The creation of social robots that can communicate more naturally and intuitively with people is one potential use for theory of mind AI.

    3. Self-Aware 
      The most advanced form of AI, self-aware AI can recognise its own existence and consciousness. These robots are capable of self-determination and decision-making, and they have the capacity to learn and adapt over time. Self-aware AI is still mostly a theoretical idea, but some academics think it could have significant effects on society and technology in the future.

Ultimately, every type of AI has varied applications in numerous domains and unique strengths and shortcomings. It is
likely that we will witness more and more complex varieties of AI that are capable of carrying out ever more difficult tasks as AI technology continues to improve.
