Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems. These processes include learning (the acquisition of information and rules for using it), reasoning (the ability to process information to make decisions), and self-correction. AI encompasses various technologies and methodologies, including Machine Learning (where algorithms improve over time based on data input), natural language processing (which allows machines to understand and generate human language), and robotics (machines capable of performing tasks). AI systems can range from simple rule-based systems to complex neural networks capable of advanced tasks like language translation, image recognition, and even playing strategic games at a competitive level. The ultimate goal of AI research is to create systems that can perform tasks that typically require human intelligence, thereby allowing for enhanced automation and decision-making in numerous fields, including healthcare, finance, transportation, and more.
