GETTING AND CLEANING DATA의 최상위 리뷰
Amazing, you get to see almost every aspect of data science. It is true that you won't get deeepeeeer, but this course allow you to not fear any kind of data science. That's amazing.
This course is really a challenging and compulsory for any one who wants to be a data scientist or working in any sort of data. It teaches you how to make very palatable data-set fro ma messy data.
Very interesting and enjoyed doing the Assignment. but the assignment instructions are not clear.A lot of time was wasted trying to figure out what data is what are what are we interested in.
It was pretty hard for someone like me who has a weakness in programming but it provided sufficient exposure and tasks for me to learn within my capabilities. I did enjoy its challenges.
