Introduction to Artificial Intelligence
Artificial Intelligence, at its core, refers to the simulation of human intelligence in machines that are programmed to think and learn like humans. This encompasses a broad spectrum of capabilities, including reasoning, problem-solving, perception, language understanding, and even creativity. The term “Artificial Intelligence” was coined in 1956 by John McCarthy during the Dartmouth Conference, which is considered the birth of AI as a field of study.
Over the decades, AI has undergone cycles of optimism and setbacks, known as “AI winters,” primarily due to limitations in computing power, data availability, and algorithms. However, the resurgence of AI in the 21st century has been propelled by advancements in these areas, particularly the explosion of big data and the development of sophisticated machine learning algorithms.
Defining AI: Narrow vs. General AI
AI systems can be categorized into two main types:
