Artificial intelligence (AI) is a field of computer science focused on creating systems capable of performing tasks that typically require human intelligence. These tasks include learning, reasoning, problem-solving, perception, and natural language understanding. AI encompasses various subfields such as machine learning, where algorithms improve through experience, and neural networks, which mimic the human brain's structure and function. Applications of AI range from virtual assistants and autonomous vehicles to predictive analytics and personalized recommendations. By enabling machines to process and analyze vast amounts of data, AI enhances decision-making, automates complex processes, and drives innovation across industries.
