   I felt like they were to math heavy. However, I'm struggling on how to learn deep learning.

These statements are in contention. You will never really understand machine learning without learning a fair bit of the math.

I do think a lot can be done on the presentation of the material, and certainly don't think much of credentialism.

Honestly, in your shoes I would look for a position where you can learn from people internally, rather than try and qualify yourself first. Even if you do a bunch of online learning and toy problems, you are going to flail about if you don't have a strong mentor in your first position.

What related/supportive skills do you have to bring to a group that is doing ML ?

edit: I should add that you don't really have to understand much these days to integrate (some) ML into a system, but you aren't going to get very far into modeling or understanding issues without some background. You can only get so far with black boxes.

Thanks for your reply. I do agree with you, in general, and have been trying to get myself involved in more ML projects at my current work.

I have around 8 years of professional software experience (C++/C#) and have fiddled around with some rudimentary machine learning for work, like linear regression, k-means clustering, etc. I have a decent idea of how/why they work, but have fallen flat on my face when learning the theory behind more complicated algorithms, e.g. Hessians from Andrew Ng's class. In my experience, many classes tend to focus on a ground up approach. With higher level frameworks like Keras, how necessary is this?

I would wager that you've heard this line before, but it all depends on the particulars of what you are trying to do. If you want to develop a first principles understanding of what's going on its probably important. It will be less important if you just need to see the empirical performance of n established method on your new dataset.

Reading in between the lines, maybe this is a question about Newton's method? One of the general strategies shared between software development and "mathematical" (for lack of a better word) science and engineering is to reduce a complex problem to a known use case. If you've got a grasp on linear regression, take a look at Newton's method in this case. You may be pleasantly surprised to see that the Hessian is constant. This might make it easier to make the connection to relevant topics such as the convergence rate of the method and the connection to the uncertainty in the fit.
