Artificial intelligence (AI) refers to the simulation of human-like intelligence processes by computer systems. These processes include learning (the ability to acquire information and rules for using it), reasoning (the capacity to solve problems logically), and self-correction. AI can manifest in various forms, such as machine learning, where algorithms improve from experience, and natural language processing, which allows machines to understand and respond to human language. Applications of AI span numerous fields, including healthcare, finance, transportation, and entertainment, enabling advancements like predictive analytics, autonomous vehicles, and virtual assistants. Overall, AI aims to create systems that can perform tasks that typically require human intelligence, enhancing efficiency and capabilities across different sectors.
