One interesting fact (which is not quite intuitive) is that one way they improved the WiFi network performance was by disabling the radios on a number of the access points in the hotel.
Less is more in some circumstances.

And later they increased interference, in order to add a 4th channel.
It's all about tradeoffs...that's why they pay engineers the (market-competitive) bucks.
(pretty sure Cisco has an equivalent but I forget its name...)
Postscript: They talk about HP buying Colubris, but don't think the Colubris-legacy equipment is current-HP stuff; they went and bought 3Com in 2010, and I think that's where most of their current offerings come from.
But you will never be able to completely remove the human from the equation. A proper wireless site survey with someone walking around and taking readings pre/post AP installation is really the best way to do things. I'm not really a WLAN guy but I work with some really bright people who are. There is a lot of depth to this problem that we should not expect to be solved anytime soon by AI.
