Artificial intelligence (AI) refers to the simulation of human intelligence processes by computer systems. This encompasses a variety of capabilities, including learning (the acquisition of information and rules for using it), reasoning (the ability to solve problems and make decisions), and self-correction. AI technologies can be categorized into two main types: narrow AI, which is designed for specific tasks (like facial recognition or language translation), and general AI, which would have the ability to understand, learn, and apply intelligence across a wide range of tasks similar to a human. AI utilizes various techniques, including machine learning, neural networks, natural language processing, and computer vision, to perform tasks that typically require human cognition. Its applications are vast, influencing industries such as healthcare, finance, transportation, and entertainment, while also raising ethical considerations around privacy, bias, and autonomy.
