I'm sure my karma rating will take a hit, but my first thought was -- "Someone developed a program to replace Mike Arrignton and his ability to insult interviewees?"

But in all seriousness, the links to journals are your best resource for specific topic areas. I've spent a lot of time in data modeling, computer vision, etc. It is a lot about providing specific models (with some minor adaptation / dynamism in the algorithm) to provide for "learning" / "adjustment".

So start with areas that are directly related to your interests and try and iterate/generalize from there.
