If you are a working professional interested in growing your career in data science or big data, I highly recommend Data Science Dojo. Raja will teach you, in the span of two short days, how to be dangerous with data science. He will teach you the basics of exploratory data analysis, R, and model building and testing. It’s immediately clear that Raja loves to teach, and his passion for data science is infectious. Best of all, Raja will teach you about the big pitfalls in data science. During the Kaggle competition, you will work with a group of motivated students who took the class with you to apply your newly-minted skills. 10/10 would sign up again!
