This video explains the relationships between Artificial Intelligence (AI), Machine Learning, Deep Learning, and Generative AI. AI broadly aims to simulate human intelligence. Machine learning allows computers to learn from data without explicit programming. Deep learning uses neural networks to achieve this, often in unpredictable ways. Generative AI, fueled by foundation models (like large language models), creates new content (text, audio, video), exemplified by chatbots and deepfakes. The video highlights the recent explosive growth and widespread adoption of generative AI.
