An interesting post in need of a reference to past work:

http://www.mitpressjournals.org/doi/abs/10.1162/jocn.1991.3....

nearly 25 years old and 13k references, so it's pretty well studied...!

Yeah that's a great paper, and I definitely used it to learn more while I was writing this post up. If anyone else wants it, here's a direct link: [http://www.cs.ucsb.edu/~mturk/Papers/mturk-CVPR91.pdf].

I really should add a section of resources that I found useful. Thanks!
