Machine Learning/Andrew Ng Coursera: Week 2 Unzipping Problem & Fix

In week 2, after I downloaded the exercise zip file “machine-learning-ex”, I found that I could not unzip it in Mathlab online.

Here is the fix:

After clicking the machine-learning-ex provided in the session, when the window pop up, DO NOT click on SAVE but choose OPEN WITH, then click OK.

You will get a zip local file named as “machine-learning-ex-1.zip”. Don’t be mistaken by the file name. It actually includes all the exercise.

Upload this zip file to matlab online and run unzip, you’ll surprisingly find that it gets unzipped into a folder named “machine-learning-ex”, under which ex1–8 are included.

P.S. I’m a mac user. Not sure if windows users get the same problem.

Happy Studying!
