    Our preprint that creates embeddings for over 100k medical concepts using data from 60 million patients, 1.7 million journal articles and 20 million notes is up: bit.ly/2HbYoyx Pretrained embeddings: bit.ly/2GvqQ0X Interactive explorer bit.ly/2GVNu1U

    This shouldn't surprise anyone. If you have tabular data, a small number of variables, and a modest sample size there is *no* reason to expect ML to be superior. However, I don't think this is the scenario most have in mind when thinking about potential for ML in medicine

    Machine learning/artificial intelligence are viewed as the future of predictive analytics. This systematic review shows no performance benefit of machine learning over logistic regression in clinical prediction models. jclinepi.com/article/S0895-…

    Language models are known to exhibit bias and it seems that GPT-3 is no different in this regard, but it is always shocking to see. I gave it the first prompt and had it generate the rest.

    Self-driving cars are often used an example of how adversarial attacks can do harm in the real world. In our new preprint, @samfin55, @zakkohane, and I argue that medicine is the perfect storm of incentive + opportunity for adversarial attacks: arxiv.org/abs/1804.05296

    A few nuggets from @geoffreyhinton's talk from earlier today at the #ml4h unconference. First up, the distinction between statistics and AI (and presumably ML by implication). Overall, I think these are pretty clean contrasts:

    One of the things I've learned from straddling the worlds of machine learning, statistics, and epidemiology is that everyone has their own definition for what "nonparametric" means
