Neflix algorithm

The fact that the winning Netflix algorithm was never implemented doesn’t get enough publicity. It’s a good example of things modelers create without being shackled by engineering concerns. The other thing these competitions (like Kaggle) get to avoid is having to integrate their model into a workflow.

But I guess really these are only concerns for those of us who create models for other humans to use. If you are creating models that computers use to, say, trade stocks, knock yourself out!
