Attention conservation notice: These are just loose thoughts on a topic that I've been thinking about for a few years. It's important to point out that I'm far from an expert in either machine learning or medicine. Also, I'm not a doctor. When I was applying to med school four years ago, I often wondered why machine learning wasn't used more commonly in medicine. I thought to myself, if I can get a statistical recommendation of what movie I will most likely enjoy from Netflix, why can't I get a statistical recommendation for what treatment will most likely help me at the doctor?
