Artificial Intelligence AI: What it is and How it Works


Artificial Intelligence AI is a rapidly growing field, with the potential to revolutionize a wide range of industries and change the way we live and work. But what exactly is AI, and how does it work? In this article, we will take a closer look at AI, exploring its definition, capabilities, and how it is being used today, and also providing some examples.

What is Artificial Intelligence AI? 

Artificial Intelligence is a branch of computer science that deals with the creation of intelligent machines that can perform tasks that typically require human intelligence, such as recognizing speech, understanding natural language, and making decisions.

There are two main types of AI:

  • Narrow AI: This type of AI is designed to perform a specific task and can only perform that task. Examples of narrow AI include speech recognition, image recognition, and decision-making systems.
  • General AI: This type of AI is able to perform any intellectual task that a human can. However, General AI does not exist yet.

How Artificial Intelligence AI works?

AI systems are based on a combination of machine learning, natural language processing, computer vision, and other innovative technologies. To be more specific, Machine learning is a method of teaching computers to learn from data without being explicitly programmed. Furthermore, this allows AI systems to improve their performance over time as they are exposed to more data.

The process of building an AI system can be broken down into several steps:

  • Data collection: Firstly, data is collected and labeled. For example, if the AI system is being built to recognize images, data would be collected and labeled images.
  • Training: Next, the AI system is trained on this data. The system is presented with the labeled data and learns from it.
  • Testing: After training, the system is tested on new data to ensure that it can accurately perform its task.
  • Deployment: Once the system has been tested and is performing well, it is deployed in the real world.

Applications of Artificial Intelligence AI 

Artificial intelligence is being used in a wide range of industries, from healthcare to finance, retail to manufacturing, and more. Some of the most notable applications of AI include:

  • Healthcare: AI analyze medical images and make diagnoses, assist with surgical procedures, and create personalized treatment plans. (e.g. IBM Watson for Oncology, Radiology and Pathology)
  • Finance: AI identify fraudulent transactions, predict market movements, and make investment decisions. (e.g. Robo-advisers, anti-fraud systems)
  • Retail: AI analyze customer data, make recommendations, and create personalized marketing campaigns. (e.g. Amazon’s product recommendations)
  • Manufacturing: AI optimize production processes, predict equipment failures, and automate tasks. (e.g. Tesla Autopilot, Self-driving cars)
  • NLP : AI is being used in natural language processing in various fields like customer service with chatbots, language translation and content generation like Chat GPT.
  • Generative models : AI is being used in models like DALL-E to generate images from text description.

Ethical concerns and considerations 

As AI systems become more advanced, there are a number of ethical concerns and considerations that need to be taken into account. One of the most significant concerns is the potential for AI to be used to automate tasks, leading to job displacement. Additionally, AI systems may perpetuate existing biases if they are trained on biased data. Also, the AI can be used in a way that can be harmful to society, such as cyber attacks, manipulation of public opinion, or even as weapon systems.


Finally, Artificial Intelligence is a rapidly growing field that has the potential to revolutionize a wide range of industries and change the way we live and work. From healthcare to finance, retail to manufacturing, and more, AI systems are already being used to analyze data, make predictions, and automate tasks.  Additionally, by providing examples of AI applications in different fields it’s easier to understand the scope of this technology, and how it will affect every aspect of our life. With AI already proving to be a valuable asset in many industries, it is likely that we will see continued growth and development in this field, and it will be important for society to adapt and take advantage of the benefits it offers.
