Weak AI or Narrow AI refers to artificial intelligence that is designed to perform a specific task or set of tasks within a limited domain, rather than possessing a general intelligence that can apply to any task.

Weak AI systems are typically focused on a specific problem or application, such as speech recognition, image classification, or playing chess. They are designed to excel at that particular task and can often outperform humans in that domain. However, they do not have the ability to apply that knowledge to other tasks or domains.

Weak AI is sometimes referred to as “narrow AI” because of its limited scope. It is the most common form of AI that is currently in use and is used in a wide variety of applications, such as virtual assistants, fraud detection, and recommendation systems. It is also the foundation for more advanced AI systems, such as autonomous vehicles and robots, which require a combination of narrow AI techniques to perform complex tasks
