What is Artificial Intelligence?

Artificial Intelligence (AI) refers to the development of computer systems of performing tasks that require human intelligence. AI aids, in processing amounts of data identifying patterns and making decisions based on the collected information. This can be achieved through techniques like Machine Learning, Natural Language Processing, Computer Vision and Robotics. AI encompasses a range of abilities including learning, reasoning, perception, problem solving, data analysis and language comprehension. The ultimate goal of AI is to create machines that can emulate capabilities and carry out diverse tasks, with enhanced efficiency and precision. The field of AI holds potential to revolutionize aspects of our daily lives.

What are examples of AI technology and how is it used today?

  1. Machine learning: This approach involves building algorithms that can learn patterns in data and make predictions based on that data. There are three types of machine learning, Refer to the article mentioned below:
    1. Supervised learning
    2. Unsupervised learning
    3. Reinforcement learning
  2. Natural language processing (NLP): This NLP approach deals with the interaction between computers and humans through natural language. It involves tasks such as text and speech recognition, translation, and sentiment analysis.
  3. Robotics: This Robotics approach involves the use of AI to design, build, and control robots. It involves tasks such as perception, decision-making, and movement.
  4. Computer vision: This computer vision approach deals with the processing and analysis of visual information from the real world. It involves tasks such as image recognition, object detection, and scene understanding.

AI has the potential to revolutionize many industries and fields, such as healthcare, finance, transportation, and education. However, it also raises important ethical and societal questions, such as the impact on employment and privacy, and the responsible development and use of AI technology.

Why is artificial Intelligence important?

Today, the amount of data in the world is so humongous that humans fall short of absorbing, interpreting, and making decisions of the entire data, no, even part of the data. This complex decision-making requires beings that have higher cognitive skills than human beings. This is why we’re trying to build machines better than us, in other words, AI. Another major characteristic that AI machines possess but we don’t is repetitive learning. Let consider an example of how Artificial Intelligence is important to us.Data that is fed into the machines could be real-life incidents. How people interact?chow people behave? how people react? etc. So, in other words, machines learn to think like humans, by observing and learning from humans. That’s precisely what is called Machine Learning which is a subfield of AI.  Humans are observed to find repetitive tasks highly boring. Accuracy is another factor in which we humans lack. Machines have extremely high accuracy in the tasks that they perform. Machines can also take risks instead of human beings. AI is used in various fields like: 

  • Health Care
  • Retail
  • Manufacturing
  • Banking

What are the types of artificial intelligence?

AI can be broadly classified into two:  

  1. Narrow AI: This type of AI is also referred to as “weak AI”. Narrow AI usually carries out one particular task with extremely high efficiency which mimics human intelligence. An example would be any computer game where one player is the user and the other player is the computer. What usually happens is, the machine is fed with all the rules and regulations of the game and the possible outcomes of the game manually. In turn, this machine applies these data to beat whoever is playing against it. A single particular task is carried out to mimic human intelligence.
  2. Strong AI: Also referred to as “general AI”. Here is where there is no difference between a machine and a human being. This is the kind of AI we see in the movies, the robots. A close example (not the perfect example) would be the world’s first citizen robot, Sophia. She was introduced to the world on October 11, 2017. Sophia talks like she has emotions.

There are 4 main types of AI :  

  1. Reactive machines: These are the most basic type of AI and are purely reactive as the name suggests. They neither can form memories nor can use past experiences to form decisions. An example would be IBM’s Deep Blue chess-playing supercomputer which is mentioned above. Deep Blue beat the international grandmaster Garry Kasparov in 1997. It can choose the most optimal of the chess moves and beat the opponent. Apart from a rarely used chess-specific rule against repeating the same move three times, Deep Blue ignores everything before the present moment, thus not storing any memories. This type of AI just perceives the world, the chess game in the case of Deep Blue, and acts on it.
  2. Limited memory: These machines can look into the past. Not the ability to predict what happened in the past, but the usage of memories to form decisions. A common example could include self-driving cars. For example, they observe other cars’ speed and directions and act accordingly. This requires monitoring of how a car is driven for a specific amount of time. Just like how humans observe and learn the specifics. These pieces of information are not stored in the library of experiences of the machines, unlike humans. We humans automatically save everything in the library of our experiences and can learn from it, but limited memory machines can’t.
  3. Theory of mind: These are types of machines that can understand that people have beliefs, emotions, expectations, etc., and have some of their own. A “theory of mind” machine can think emotionally and can respond with emotions. Even though there are close examples of this kind of AI like Sophia, the research is not complete yet. In other words, these machines have a notion of not just the world, but also the existing entities of the world, like human beings, animals, etc. These machines will be capable of answering simple “what if” questions. They’ll have a sense of empathy.
  4. Self-Awareness: These types of machines can be called human equivalents. Of course, no such machines exist and the invention of them would be a milestone in the field of AI. These basically will have a sense of consciousness of who they are. The sense of “I” or “me”. Here’s a basic example of the difference between “theory of mind” and “self-awareness” AI. The feeling of I want to play is different from the feeling of I know I want to play. In the latter, if you notice, there is a sense of consciousness and is a characteristic of a self-aware machine, while the former feeling is a characteristic of a theory-of-mind machine. Self-aware machines will have the ability to predict others’ feelings. Let’s hope the invention is not so far away.

What are the applications of AI?

Artificial Intelligence (AI) has a wide range of applications and has been adopted in many industries to improve efficiency, accuracy, and productivity. Some of the most common uses of AI are:

  • Healthcare: AI is used in healthcare for various purposes such as diagnosing diseases, predicting patient outcomes, drug discovery, and personalized treatment plans.

  • Security: AI is used in security for tasks such as facial recognition, intrusion detection, and cyber threat analysis.
  • Natural Language Processing (NLP): AI is used in NLP for tasks such as speech recognition, machine translation, and sentiment analysis.

These are some of the most common uses of AI, but the applications of AI are constantly expanding and evolving, and it is likely that new uses will emerge in the future.

What will be the future of AI?

The future of AI is likely to involve continued advancements in machine learning, natural language processing, and computer vision, which will enable AI systems to become increasingly capable and integrated into a wide range of applications and industries. Some potential areas of growth for AI include healthcare, finance, transportation, and customer service. Additionally, there may be increasing use of AI in more sensitive areas such as decision making in criminal justice, hiring and education, which will raise ethical and societal implications that need to be addressed. It is also expected that there will be more research and development in areas such as explainable AI, trustworthy AI and AI safety to ensure that AI systems are transparent, reliable and safe to use.
