Artificial intelligence (AI) is a field of computer science that focuses on the development of systems capable of performing tasks that normally require human intelligence, such as learning, reasoning, problem-solving, perception, language understanding, and decision-making. AI systems operate by processing data using algorithms and mathematical models to identify patterns, make predictions, and select actions that achieve defined goals.
Modern AI systems commonly rely on machine learning, where models are trained on large datasets to improve performance through experience, and deep learning, which uses multi-layer neural networks to learn complex representations of data. Techniques used in AI include supervised, unsupervised, and reinforcement learning, as well as symbolic methods such as rule-based reasoning and knowledge representation. AI is applied in areas such as computer vision, speech recognition, natural language processing, robotics, healthcare, finance, cybersecurity, and autonomous systems.
AI systems do not possess consciousness, understanding, or intent. Their behavior is determined by their training data, algorithms, and constraints defined by human designers, and their outputs reflect statistical patterns and optimization processes rather than human-like awareness or judgment.
