46th position

Today I’m at the 46th position of the Online Product Sales leadership board. Not a raving result, but it’s a start. And moreover, it is the improvements that come with each model that make me want to try more and do better.

I think I have squeezed most of the improvements randomForest is able to give me. Now I need to look for other techniques. Maybe blending a few models together, or feed models into a neural network or something. *rub hands together* I have one more week to play around before I start preparing myself for the corporate world again.
