Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems. It encompasses various technologies and approaches that enable machines to perceive their environment, reason, learn from experiences, solve problems, and make decisions. Key components of AI include Machine Learning (where computers improve their performance through experience), natural language processing (enabling machines to understand and generate human language), and computer vision (allowing machines to interpret visual information). AI applications are vast and include areas such as speech recognition, image analysis, autonomous vehicles, recommendation systems, and robotics, among others. AI aims to create systems that can operate with a level of autonomy, adapt to new situations, and perform tasks that traditionally required human intelligence.
