Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to perform tasks that would typically require human intelligence, such as visual perception, speech recognition, decision-making, and language translation. AI systems use machine learning algorithms to analyze and interpret data, learn from that data, and make decisions or predictions based on what they have learned. AI has applications in a wide range of fields, including healthcare, finance, transportation, manufacturing, and entertainment, to name a few. AI is a rapidly evolving field, with new advancements being made all the time, and it is expected to have a significant impact on society in the coming years.
