AI is an umbrella term encompassing various concepts and models related to human intelligence tasks.The history of AI dates back to the 1950s, with a formal field beginning at the Dartmouth Conference in 1956.AI has experienced waves of hype and progress, with notable milestones like IBM's Deep Blue and AlphaGo victories.AI operates based on learning from data, where supervised learning involves teaching models patterns from training data.Linear regression is a simple machine learning model that predicts data points' relationships.The learning process involves using a loss function to measure errors and adjusting parameters through gradient descent.AI subfields include machine learning, deep learning, and generative AI, each tailored for specific tasks.AI systems can exhibit intelligence through problem-solving and pattern recognition but lack true understanding, feelings, or consciousness.Models like ChatGPT generate responses based on statistical likelihoods rather than true comprehension.AI is synthetic intelligence, mimicking human thinking without replicating consciousness, relying on math and data for operations.
