Key takeaways

  • Artificial intelligence (AI) enables computers and machines to simulate human learning, comprehension, problem solving, decision making, creativity, and autonomy. But just when we think we've wrapped our heads around what it is, AI rewrites the rules.
  • The pace of innovation is accelerating so quickly that many of us struggle to keep up. And for those non-experts that try, the language and concepts can be bamboozling. This three-part "dictionary" series was created to help define key terms and provide everything you need to know about AI, the biggest revolution yet.
  • This first installation covers the AI basics - from exploring the common types of AI widely used today, to discussing key AI technologies, including machine learning, deep learning, and natural language processing.
