In this episode, Michael Burke and Chris Detzel discuss the role of data in machine learning and AI. They define machine learning as the process of identifying patterns in data to create value and AI as a computer's ability to make decisions on its own. They also explain that data science is the larger sphere that encompasses both of these fields. They then go on to discuss the role of data in machine learning and how it helps organizations make better decisions. Finally, they use the analogy of driving a car to explain the importance of data in machine learning.
