== History ==
Artificial intelligence has a rich and complex history that dates back to the early 20th century, with theoretical groundwork laid by pioneers such as [[Alan Turing]], whose introduction of the Turing Test in 1950 provided a criterion to evaluate a machine's capability to exhibit intelligent behavior indistinguishable from a human.
=== Early Developments ===
=== Early Developments ===
The formal foundation of artificial intelligence can be traced back to the 1950s. In 1956, the Dartmouth Conference, organized by John McCarthy, Marvin Minsky, Nathaniel Rochester, and Claude Shannon, is acclaimed as the birthplace of AI as a scholarly discipline. Early AI development focused on symbolic methods and problem-solving—the creation of algorithms that could solve mathematical problems and play games such as chess.


=== The Rise and Fall of AI ===
The roots of AI can be traced back to classical philosophy and early work in mathematics and formal logic. In 1956, the term "artificial intelligence" was coined at the Dartmouth Conference, which marked the beginning of AI as a field of study. Early AI programs in the 1950s and 1960s included [[Logic Theorist]], which proved mathematical theorems, and [[General Problem Solver]], which attempted to solve problems using a generic algorithm.
The periods known as "AI winters" occurred in the late 1970s and late 1980s when the initial enthusiasm triaged into disillusionment due to the limitations of existing technologies and the high expectations set by early pioneers. Funding and interest in AI research dwindled during these phases. In contrast, interest surged again in the 1990s and 2000s fueled by advances in computational power, algorithmic design, and the availability of vast amounts of data.
 
=== The AI Winter ===
 
Throughout its history, AI has experienced fluctuations in funding and interest, notably during periods referred to as "AI winters." In the 1970s and again in the late 1980s, optimism waned due to the limitations of existing systems, leading to reduced financial support and interest from both industry and academia. These periods highlighted the challenges inherent in developing truly intelligent systems.
 
=== Resurgence in the 21st Century ===
 
Despite facing challenges, AI experienced a renaissance in the 21st century, fueled by advancements in computational power, the availability of large datasets, and the development of new algorithms, particularly in the fields of [[machine learning]] and [[deep learning]]. The shift towards data-driven approaches proved pivotal, enabling state-of-the-art performance in numerous applications ranging from natural language processing to image recognition.
