I've been working on the Kaggle Amazon Employee Access competition. I got a late start and am in a rush to try out a new model. Unfortunately, the current R implementation is slow.
I left it running overnight and woke to find it almost done. Just when my excitement was peaking, I hit a bug and the routine stopped. I didn't write the code in a way that checkpointed the progress so all six hours of computation is lost. Biscuits!
Notes to self:
