Machine Learning Isn’t Data Science

Machine Learning is a type of analysis you *might* perform as part of Data Science. Stated another way, Machine Learning isn’t a necessary condition of Data Science (Statistics is though!). If you happen to be doing a predictive task, you’re reaching for supervised learning. If you happen to be doing descriptive/exploratory analysis, you *might* reach for unsupervised learning. As for reinforcement learning, it’s not as popular as supervised learning or unsupervised learning, and even less popular in Data Science.
