 What is AI technology and How it works – A Brief Guide

Have you ever thought of how AI tool Chatgpt answers your queries when you ask a question to it, how Alexa works, google voice assistant, apple Siri works, here the concept of AI comes into picture. All these tools use the concept of AI.

The term AI stands for artificial intelligence. Artificial Intelligence refers to the simulation of human intelligence in computer systems that are programmed to solve real world problems like a human being can solve .

It is a set of technologies which are utilized by computer systems and machines to perform complex tasks that typically require human intelligence like visual perception,voice recognition, and decision making.

It has a wide variety of applications in different sectors and industries like science and technology, banking domain, healthcare, education, automobiles, robotics and many more. It has endless applications.

How AI technology works

AI enabled systems take large amounts of data from different sources. This data can exist in various forms like text, image, video, audio and many more. It analyzes large datasets for correlation and patterns, and with the help of those patterns AI predicts the future states. For example, A chatbot that is fed with text data can talk to human beings like a real person over the internet.

AI is a broader term that encompasses different fields like machine learning and deep learning. 

Machine learning is a branch of artificial intelligence that is used to make accurate predictions by utilizing historical data

Deep Learning is a subset of machine learning that can process large datasets and are able to produce more accurate results than traditional machine learning. Its foundation is based on the concept of artificial neural networks.

Weak AI and Strong AI

  • Weak AI
  • Strong AI

Weak AI

Weak AI, also known as narrow AI, are the systems that are created to complete one particular task. Weak AI is limited in scope and specializes in a particular domain. It works under a limited set of predefined conditions and lacks in general cognitive abilities associated with human beings

Its examples are 

  • Apple’s Siri
  • Amazon Alexa and other personal assistants like Cortana
  • Self driving cars
  • Chatbots
  • Google Navigations systems 
  • Google Search

Strong AI

These systems are also known as artificial general intelligence(AGI). Strong AI refers to the system of AI that possesses the ability of solving problems it’s never been trained on like a normal human being. It lacks cognitive abilities and general thinking like a normal man. This type of AI doesn’t exist yet.

Four types of AI technology

Artificial intelligence can be categorized into 4 types.They are given as below

  • Reactive machines
  • Limited memory
  • Theory of mind
  • Self awareness

Reactive Machines

They are the most basic form of artificial intelligence. These systems do not have any memory and are task specific. These AI systems cannot use past experiences to predict futures. Its example is Deep Blue machine. It is a chess playing supercomputer and designed by IBM company. This machine beat the chess champion Garry Kasparov in 1997. Another example is Google alphago.

Limited Memory

Limited memory systems have the ability to store previous data and with the help of that data it can predict the future information. They have limited memory capacity and greater possibilities than reactive machines. Self Driving cars are an example of limited memory AI machines

Theory of Mind 

This AI system can behave and comprehend like human beings. These systems have the decision making capabilities equivalent to that of human beings. This AI can understand human feelings and emotions. They have social intelligence like a human being have. In the present world, this type of AI doesn’t exist yet. Our technological research hasn’t reached this level.

Self Aware

After the establishment of theory of mind,self aware AI systems will come into existence.

They will understand human feelings and emotions, and based on that they communicate according to it with their own sentiments, and feelings. Such systems with their own feelings, emotions and consciousness are expected to be more smarter than present human beings. In the coming years, we will see such types of machines. Efforts to develop such systems are being made in this direction.

Examples of AI technology

AI concepts are incorporated in different sectors. Here are examples given below

  • Virtual Personal Assistants – Apple’s Siri, Amazon Alexa, Google Assistant, Microsoft Cortana
  • Image and speech recognition systems
  • Chatbots – Chatgpt, Google bard
  • Self driving cars
  • It is used in healthcare, education, finance and different sectors
