Artificial Intelligence (AI) refers to the simulation of human intelligence processes by computer systems. These processes include learning (the acquisition of information and rules for using it), reasoning (the ability to solve problems using the information), and self-correction. AI can categorize into two main types: narrow AI, which is designed to perform a narrow task (like facial recognition or internet searches), and general AI, which aims to understand and reason across a wide range of tasks as a human would. AI technologies encompass various techniques and methodologies, including Machine Learning (where systems learn from data), natural language processing (enabling machines to understand and generate human language), computer vision, robotics, and neural networks. The applications of AI are diverse, impacting various fields such as healthcare, finance, education, and transportation. AI continues to evolve, with research focused on improving its capabilities and ethical implications.
