This presentation provides an overview of artificial intelligence (AI) and how it works. It defines intelligence as the ability to learn from and interact with one's environment. Artificial intelligence is defined as making computers do intelligent tasks like humans. AI works using artificial neurons in artificial neural networks and scientific theorems. Neural networks are composed of interconnected artificial neurons that mimic biological neurons. Examples of AI applications include expert systems like PROSPECTOR for geology and PUFF for medicine diagnosis. Machine learning allows AI to mimic human intelligence by learning from failure, being told, or exploration. While human intelligence has intuition and creativity, AI can simulate human behavior, comprehend large data quickly, and preserve human expertise to achieve more than is known. AI is needed to
