I haven't had a lot of time to look at the offering, but can anybody tell me if these courses have any theory, or are they just for promoting specific AWS ML services without going into the underlying complexity?

I haven't looked in detail but the description strongly suggests an applied ML focus (which would be very typical of IT certifications in general). In AI/ML, there's some overlap between applied AI and research AI--e.g. you're going to want to know something about statistics in any case--but I'm not sure the distinction is always appreciated.

Is there a cert to go along with the courses?

Some online courses or groups of online courses have certs associated with them. Some don't. Whether those certs are worth anything from a job hunting perspective is going to depend on the cert and who is looking at them. Very situationally dependent.

It's worth pointing out that this recommendation behavior is only unintelligent if it has a downside, i.e. reduces Amazon's profits. Companies (and their AIs) only care about your business transactions, not whether you're annoyed. I'm sure Amazon engineering is well aware of the jokes about their recommendation engines. But their recommendation engines are not calibrated to reduce jokes, they are calibrated to increa…

That's not true, putting a product I've already ordered on my recommended list instead of something i actually want to buy is costing them money in lost sales.

People buy a lot of consumable products on Amazon. People buy a lot of things and realize how much they like and would like another for another room in the house or something. You aren't thinking broadly enough here.

How often do I buy a HP Color LaserJet printer, versus toner cartridges for it? Or ink for another printer of which it has no evidence that I own)? Yet I bought a color laser printer and my first two pages of recommendations are for other variations on the same ("Hey, you bought the wired MFP! Perhaps you want the wireless too! And I know it's a HP printer, but maybe I can suggest some Brother toner for you!").

Bad example, because printers often are consumables. ;)

If you buy the printer that is "consumable" more than once, you deserve it :)

From Amazon's perspective, it doesn't have to work for you ; it has to work on average .

In that case, it may be better to just put the hot new item in a category they know you purchase in. For instance, if I have a subscription to paper towels, maybe they should send me a subscription recommendation for toilet paper.

You're correct that Amazon should be smarter about some recommendations. I'd say give them the benefit of the doubt in that they may have found an algorithm that works most of the time (or at least when it comes to their bottom line), but edge-cases stand out to us. Still though, there could be a method to the madness. You bought a printer - are you setting up a home office? Perhaps you want a second printer for upst…

I don’t doubt there are entire divisions in Amazon that draw statistical correlations and do A/B testing to figure out what annoying emails work. Just like any other marketing agency. So you can be sure that any annoying email you get is the probably the result of years of metrics.

Checked out data science, there's a good amount of general stats in there. It's also in their interest to educate people so that they could become customers once they understand the basics/theory.
