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 use of rules to reach approximate or definite conclusions), and self-correction. There are two main categories of AI: narrow AI, which is designed to perform a narrow task (like facial recognition or internet searches), and general AI, which possesses the ability to perform any intellectual task that a human can do. AI technologies often involve machine learning, where algorithms are trained on large datasets to improve their performance over time. Applications of AI are widespread and impact various fields including healthcare, finance, transportation, and entertainment, enhancing efficiency, accuracy, and data analysis capabilities across different domains.
