During the summer, vision meetings occured many Tuesdays (2-3) and Fridays (2-3:30) in Gould Simpson 805 (as travel schedules permitted). I took a break from maintaining the activity tables. On Tuesdays we focussed on basic stats, getting through chapters 1 through 7 of "All of Statistics" by Wasserman. On Fridays we had some discussions on software infrastructure, and read papers by Hoiem et. and the image parsing paper from Zhu's group, as well as a few others that I have forgotten.
