What is artificial intelligence?

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn. These machines are designed to perform tasks that typically require human intelligence, such as visual perception, speech recognition, decision-making, and language translation. AI can be categorized into two main types:
1. Narrow AI (or Weak AI): This type of AI is designed to perform a narrow task (e.g., facial recognition, internet searches, or driving a car). It operates under a limited set of constraints and parameters and does not possess general intelligence or self-awareness.

2. General AI (or Strong AI): This type of AI would have the ability to understand, learn, and apply knowledge in a way that is indistinguishable from human intelligence. It would be capable of performing any intellectual task that a human being can do. As of now, general AI does not yet exist.

AI technologies include machine learning, where machines are trained on data to improve their performance on a task without being explicitly programmed for that task, and deep learning, a subset of machine learning involving neural networks with many layers. Other related fields include natural language processing (NLP), robotics, and computer vision.
