Artificial Intelligence (AI) refers to the simulation of human intelligence in machines programmed to think and learn. It encompasses a range of technologies and methodologies that enable computers and software to perform tasks that typically require human-like cognitive functions, such as understanding natural language, recognizing patterns, solving problems, and making decisions. AI can be broadly categorized into two types: narrow AI, which is designed to perform a specific task (like facial recognition or language translation), and general AI, which aims to exhibit human-like intelligence across a variety of tasks. AI systems learn and improve over time through techniques such as Machine Learning, where they utilize data to recognize patterns and make predictions, and Deep Learning, which uses neural networks to model complex patterns in large datasets. Applications of AI span numerous fields including healthcare, finance, transportation, and entertainment, providing significant advancements in efficiency, accuracy, and innovation.
