Hello Professor

I have doubt for below point. 

Run gradient_descent. Calculate the cost function values on the normalized data before and after, print these values.

So do we need to find cost on our original file data and on normalize data??

Thanks

No, find the cost before the thetas are trained (set them to zero to start) and after. 

FYI, in American English, "doubt" should, in this context, be replaced by "question." As written it expresses, well, doubt (and that makes me sad and anxious frownsurprise).

Some online dictionaries list doubt as a synonym (http://thesaurus.yourdictionary.com/doubt), but I get your point Mark lol.
