Hi David, very impressive of your notes, especially in this knowledge-intense machine learning conference, the way you organize diverse topics and have short summaries about them seems like a very useful skill to have. Do you have any methods/tips that you can share about your note-taking skills?
Investing in a particular set of tools has been really critical for me -- once I found that I liked the flexibility and power of latex, I put effort into simplifying the process of using it.
So, for instance, I made some macros for commands that I use frequently, and a put together a latex template that includes the packages and basic structure of documents I write. Otherwise, just practice! I forced myself to write notes during class in latex when I took information theory earlier in grad school and that helped a lot.
Hope this helps. If I think of anything else I'll be sure to come back and post!
I'm planning on putting these together to future conferences I attend, too (I'm currently a 3rd year Ph.D student so I should be attending a few in the coming years).
