Am I correct in finding this is only accessible via paying for it, or if you are currently enrolled in school? Or is there someway to gain access to this information without paying?

that is generally how books work

So what value is there in posting a link to a book? Should I set a bot to trawl Amazon for tech books and post the links here?

I believe so. This is just a link to purchase a text book.

I for one resent the idea that having a Computer Science degree somehow makes machine learning less daunting.

Someone once told me that the majority of machine learning work is statistics. If that is true, perhaps only stats majors would find it less daunting.

It's an experimental discipline implemented _using_ computers. Programming is necessary but definitely not sufficient.

I'm biased, but in my experience, stats, the math-heavy end of economics, and computational physics/chemistry/biology are all roughly as good preparation as a traditional computer science course. (Having research experience is particularly useful.)

That’s mostly the case — the line between ML and statistics is blurry. However the concerns of a practitioner of machine learning and a practitioner of statistics can be different. The ML community has a greater interest in stuff like “can I come up with a procedure to learn this thing.” Lots of practitioners don’t care about why something works as long as it works (a theorist can figure it out later).

A statistician might be more concerned with getting the modeling assumptions right and applying methods in a more rigorous manner. They might not push the envelope as much in terms of application, but that’s because they have a higher standard they hold themselves to.

However, this line is incredibly blurry and there’s plenty of more detailed write ups by people who have spent time in both communities (I have a bit of bias in that my exposure is primarily to the ML community). There are people that do applied work and theoretical work in both communities and there are good and bad practitioners in both communities.

I feel like modern ML is finding out that you can apply the chain rule to calculate derivatives cost effectively and then scaling up a really really really big equation to then iteratively converge on the answer you want.

data science is more = to statistics

I agree. ML is best explained not from a CS angle but from a maths/physics/biology angle, starting with a Single Layer Perceptron. It's possible to explain the idea of feed-forward/backpropagation computation visually without having to dive into the math of matrix multiplication, and certainly in isolation from other CompSci theory.

Personally I've found this approach, in combination with a visual explainer like the Tensorflow Playground, really effective in getting people to 'get it'. I know it doesn't even begin to cover the breadth of today's ML techniques, but as a conceptual introduction that requires little to no CompSci foundation, it works and it's a start.

Re getting people to get it, 3blue1brown has a fantastic series that feels like:

Was a perfect summary of. The visuals are excellent too.[0]
