Re: Matrix factorization Regularization

Thanks for your inquiry. The main idea is that you are missing the "prerequisites". Helpful resources: - read the course description (I hope you have done this!) where the prerequisites have been listed - lecture "how to succeed in this course" - FAQ lecture "machine learnin...

Re: exercise 3: iterate through each number

Thanks for your inquiry.

Are you sure you've run the script without any changes?

Many students promise they haven't made any changes, but I usually have to ask a few times before they admit that they have.

Re: Wget command with MacOS?

Thanks for your question. If you are on a regular computer (i.e. like Mac, Windows, or Linux that has a GUI) then you can just download the file normally using your web browser. Command line downloading (e.g. wget) is only used when we like to have the convenience of being able to download a file pr...

Re: Course Question Recommendation

My recommendation is to treat it like an exercise.

I believe you can do it. Please keep trying.

Re: Tensorflow internals

Thanks for your inquiry. This is discussed a bit in the Tensorflow 2 course, as well as the "in-depth" series of deep learning courses starting from "Data Science: Deep Learning and Neural Networks in Python". These look at Tensorflow 1, which is lower-level, and Theano, which is...

Re: Probability of Data

Thanks for your inquiry. > In this case, data is denoted by Y,X which I interpret as the intersection of events. The issue is, there is no such thing as p(w | Y | X). A simpler way to think of it is that "X" is on the "given" side for all terms (and hence effectively ignored). So...
