### Re: Multiple Linear Regression - How do we know its the local minimum of the error

2) has more to do about the "rank" of the data matrix (X), which is related to the number of linearly independent columns (i.e. features). 1) the calculus course makes the same statement (because that's the only statement which needs to be made) but obviously in more detail, e.g. with visu...

### Re: Multiple Linear Regression - How do we know its the local minimum of the error

Thanks for your inquiry. 1) One way to see is to plot it. Another way to see is to use the methods taught in my latest Calculus course. https://deeplearningcourses.com/c/calculus-data-science (However it also requires linear algebra knowledge, but I haven't released that course yet) 2) It's not alwa...

### Re: ARIMA in Code(pt1)

Thanks for letting me know about this. Google Colab updates their pre-installed libraries every so often, so this will happen. I will have to update the notebooks with the new code. If you are taking the Time Series Analysis course you can find similar notebooks with updated code since they all upgr...

### Re: Course Notebooks

Are you willing to at least state why you're not willing to discuss this?

I'm welcoming you to openly talk about this here and all of a sudden you disappear. Yet originally, you seemed very eager for this feature. I am giving you a chance to state your case. Why are you hesitant?

### Re: Taking Logs

Yes, in fact, all of this is discussed in my new calculus course.

In many modern ML / statistics textbooks, they use "log" with the implicit assumption that it's "ln" (base e).

### Re: Course Notebooks

I'm always open for discussion. However, no student (NONE!) has ever answered my questions sufficiently. I keep asking: "Why do you need to automate running the code?" If you can give me a response, then I would be happy to discuss. However, I think most students realize they have been dis...

### Re: Course Notebooks

What's the reason you're trying to automate this process?

Generally, the course is designed to be optimized for learning, and as such, it is optimized for understanding the code, rather than just running it blindly (automated).

### Re: Course Notebooks

Thanks for your inquiry. Remember that Python code is the same, no matter the format. See the FAQ Lecture: "Proof that using Jupyter notebook is the same as not using it". It would be the same as if I had provided you with a *.py file (which is the format used in some older courses). Would...
