CDA is challenging, but at the same time very rewarding. DMSL pushes you towards using R packages as a black box and even to copy and tweak the sample R code provided. This is only my opinion, but no comparison here, CDA is a much better class if you want to learn. DMSL teaches you almost nothing beyond ISYE6501. 3.Homework 1: Quiz format for True/False and Multiple Choice Due May 30 at 11:59pm Points 40 Questions 25 Available May 17 at 8am - May 30 at 11:59pm 14 days Time Limit None Instructions.

For KNN and SVM, you can randomly downsample the training data to size m = 5000, to improve computation ...

This is a very good course. I think the difference between CDA and ML from CS is that there is much more theoretical aspect in CDA. At least one question per homework asks you to do the algorithm by hand so you truly understand what the algorithm does. Homework 1-3 are very tough but after Homework 4, the difficult drastically decreases.
