Just a quick note.  I recently (last night) went to a talk on using AI for data mining. The interesting thing to me was the use of genetic algorithms to generate decisions trees.  This was essentially a program that took nodes from a binary tree and ditched the ones that were not performing and spliced in something with new parameters.

Also evidently some cities use RFID tags on trash cans to indicate when they are full and need dumping.  Evidently the future happened when I was looking the other way.  More later.
