> This is a fantastic article for intermediate beginners. On HN, everyone is a senior data scientist working with Spark and Keras and Tensorflow and deep learning.

Although there is a ML/AI selection bias in HN, there are certainly a lot of people on HN who fall into the intermediate/beginner category (there is a lot of demand for R tutorials which I have been working on), although I would argue that dplyr can legitimately be used at the advanced level. And certainly Keras/Tensorflow is overkill for common business problems.

There are definitely a lot of people who fall into those categories, but the articles/links give the impression that everyone is senior. Which is why it's great when articles like this come around.
