Any recommendations for the connection between ML and communications,
Not sure if you're looking for a specific application or COTS technology rec, which I don't have the foggiest about-- but here's a white paper from 2019, and a query of "machine learning artificial intelligence darpa" kicked up some interesting results.
Google Scholar
*Okay so I'm going to add something-- the intersection between human behavioral prompting using artificial intelligence (if this occurs (end user does x), this will then happen (technology does y) prompting or conditioning end user to do (AB), can simultaneously prompt AI learning in whatever program is running the above described sequence, by using the same theory/formula/code on the backend...
an example (of the last - using the same theory/formula/code on the backend) is Google keyboard.
I was an alpha tester for a mobile keyboard beginning in the mid-aughts- because...anyone on the bleeding edge of technology is a massochist.
The keyboard has come a long way since '07-08, but one thing that hasn't changed, is that my application has a huge random vocabulary, that is very specific to me and it's an example of training AI. At first, for years, it was very, very slow to learn. Now it's very fast. This isn't unique to my keyboard. This increase in speed was not because of manually adding new dictionary words. It's because of backend learning the end user doesn't see.
Not sure if this response is woefully simplistic for what you're asking using the specific definition of communication, or misses the mark entirely - and not what you're asking at all, so in that case, just disregard.
The topic is super interesting.
