AI encompasses various techniques, including machine learning, where algorithms are trained on data to make predictions or decisions without being explicitly programmed, and deep learning, which involves neural networks with many layers of interconnected nodes inspired by the structure of the human brain.
AI applications range from everyday technologies like virtual assistants (e.g., Siri, Alexa) and recommendation systems (e.g., Netflix, Spotify) to more specialized fields such as medical diagnosis, autonomous vehicles, and natural language processing.
Overall, AI aims to create systems that can perform tasks that would normally require human intelligence, revolutionizing industries and society in the process.
