"Machine learning" used to be a safe haven. You could flee there to escape the Terminators and brain-on-a-chip graphics. Business PR deliberately killed that. They wanted their ML algorithms to be refered to as AI, so they could f

This seems contradictory: > AI can't predict social outcomes > In most cases, manual scoring rules are just as accurate So manual scoring rules don't work either for predicting social outcomes? There is some magic sauce that

Strange that I think that a sarcastic reply that goes a bit further in moral punishment would be indistinguishable from a real reply these days. Mercer was practically forced to resign due to the backlash that his democratic political views

So, assuming nothing against the law, how would they do it legitly? I am guessing: - Treat the markets as a complex dynamical system and use the tools from statistical physics such as the Gibbs Ensemble, to derive internal states from input

Television incentivizes forgetable reality TV, the radio incentivizes meaningless poppy music, social media incentivizes bickering about the controversies of today. But, nowadays, you can also use your TV to watch a French arthouse film, to

You seem to be under the assumption that rebalancing is always bad or ignorant. That techniques, such as SMOTE, are only used to produce better-looking results and pull the wool over someones eyes. This is simply not true. Rebalancing is no

Thanks! That article has a lot of critique and I also like that the author collected the responses from one of the authors. But, to me, most of the critiques seem uninformed (not made by ML practicioners) and focus on the ethics (where I ag

Many statistical assumptions are regurarly broken, for pragmatic reasons (it just works better), or because the world is not static (and so the IID assumption is broken). There is an entire subfield of learning on imbalanced datasets, which

Rebalancing an imbalanced dataset is common in industry and academicia. You use that when you focus on accuracy, to make claims like: We were 54% accurate on classifying sexuality of females easily interpretable, without needing a distribut
