1. The Birth of AI (1940s-1950s):
The roots of AI can be traced back to the work of pioneers like Alan Turing, who developed the concept of a universal machine capable of performing any computation.
In 1950, Turing introduced the "Turing Test" as a measure of a machine's ability to exhibit human-like intelligence in natural language conversation.
2. Dartmouth Workshop and the Birth of AI as a Field (1956):
The term "Artificial Intelligence" was coined by John McCarthy, and he organized the Dartmouth Workshop in 1956, which is considered the birth of AI as a formal field.
Researchers at the workshop aimed to develop machines that could simulate human intelligence.
3. Early AI Achievements (1950s-1960s):
In the late 1950s and early 1960s, early AI programs were developed to perform tasks like playing chess (e.g., IBM's "IBM 704" and "IBM 7090" programs) and solving algebra problems.
The "Logic Theorist" by Allen Newell and Herbert Simon proved mathematical theorems.
4. The AI Winter (1970s-1980s):
Progress in AI was slower than expected, leading to a period known as the "AI Winter." Funding for AI research decreased, and some believed AI was overhyped.
Expert systems gained popularity during this time, focusing on rule-based systems that emulated human expertise in narrow domains.
5. Emergence of Machine Learning (1980s-1990s):
Machine learning, a subset of AI, gained prominence with the development of algorithms like neural networks and decision trees.
Backpropagation, a key neural network training algorithm, was invented.
6. Machine Learning and Data Revolution (2010s-Present):
Advances in machine learning, fuelled by the availability of large datasets and powerful computing, led to breakthroughs in areas like natural language processing (NLP) and computer vision.
Deep learning, particularly deep neural networks, revolutionized AI applications, including speech recognition and image classification.
The emergence of AI in applications such as autonomous vehicles, virtual assistants, and recommendation systems has become mainstream.
