Artificial Intelligence (AI) refers to the ability of machines to perform tasks that typically require human intelligence, such as visual perception, speech recognition, decision-making, and language translation. AI is a broad field that encompasses a range of techniques, including machine learning, deep learning, natural language processing, and computer vision.

Machine learning is a subset of AI that involves training algorithms to learn patterns in data, without being explicitly programmed. Deep learning is a type of machine learning that uses neural networks with multiple layers to learn increasingly complex representations of data. Natural language processing is a subfield of AI that focuses on enabling machines to understand and generate human language. Computer vision is another subfield of AI that focuses on enabling machines to interpret and analyze visual information.

AI has numerous real-world applications across various domains, including healthcare, finance, transportation, customer service, and entertainment. As technology advances, AI continues to evolve and has the potential to revolutionize industries and enhance various aspects of human life.
