Success (Relatively)
March 13, 2009
So now that the data is sorted by date, as the Gravity team describes in their paper, and everything worked according to plan. It ran in 13 epochs instead of 50-ish and got a .9217 RMSE instead of 1.0014.
Now I can finally start playing around with the other things they've tried. Maybe at some point I can try something of my own.
