Thanks for writing this. I had it on my mind but am usually too lazy to write long comments. I am a data scientist and I do some ML at work that is actually core the business (Learn To Rank for an aggregator). Whenever I read some article about data science on HN I can never relate to what they say. 'Data drift' sounds like some BS one tells their manager when they don't understand what's really happening. > I have done enough research on production ML now to know that it pays to simply overfit to the most recent data and constantly retrain. Successful companies do this. As long as they are not AB tested statement likes these are worthless. I recently tried updating a model daily vs weekly and it made aboslutely no difference so why would I care ? Anyway, thanks for your comment I know I'm not alone.
