And refuse to serially update it ;-) Which is why no working statistician is really 100% Bayesian (intractable in many cases) or 100% frequentist (obviously wrong in some cases). We all use Bayes' Rule (don't need to be "a Ba

This (and dendritic cell vaccines, and inactivated poliovirus, and...) all can be traced back to an observation that the only people with good outcomes from glioblastoma were those with listeriosis in the past. Steve Forman at City of Hope

Google wasn't evil, at least not before the IPO (which is when I worked there). People took the slogan seriously and based decisions on it. I don't know what happened.

RF is appallingly difficult to re-use for inference, though. At least with a DNN or CNN you can pop open the hood and see what the model is doing at various points. Tradeoffs, tradeoffs everywhere. It's almost like traditional mathem

Logistic won't do anything useful for text, to be sure, although an HMM often will (or if you have continuous-valued sequences, a Kalman filter often will do the same). Logistic or multinomial can be tremendously handy for picking up

Yeah, sorry about that. By the time I realized the way the tone had come off, I had managed to "noprocrast" myself off the site. I need to write better hot takes

Sorry, I should have used the phrase "inverse cdf". If you can map a pile of data onto 0 to 1 (i.e. by ranking it) then you can invert it onto the values that occupy those quantiles for a Gaussian. This is nice because you can us

quantile regression is computationally intensive and inverse transformations usually less so. Although you could certainly make the case that, given enough data, quantile regression better captures what we actually want to find, most of the

re: normit/inverse transformation: Pet theory? This isn't a theory, it's a simple inverse transformation. It's used all the time. George Box showed how to do a 2D version of it in the 1950s. Normit may be a pet name

1) it is pretty amazing that normit transformations (map the quantiles of a non-normal distribution onto a Gaussian and use that) don't seem to be on this guy's radar. We use distributions with linearly additive and affine invari

Yes, the author is serious that investors worry about losing billions of dollars. If your house or savings became worthless overnight, I suspect you'd be worried too. It's a statement of fact. If UCARTs come to prominence on the

That's a function of perverse incentives, rather than some sort of immutable truth. If there were stronger penalties for (e.g.) cartel-like pricing (e.g. TKIs), and more price transparency for the true costs of care (ibid), we might s

Calorie counts are typically adjusted; manufacturers don't typically just toss a bag of, say, Ho-Hos in a bomb calorimeter and use the raw numbers from Igor or whatever recording program happens to be around. The usual macronutrient va

Even in ICUs and NICUs, where it already is being automatically gathered and fed, it turns out that making sensible design and training decisions to get usable performance is harder than anticipated. News flash, dermatologists don't ju

You present this as binary: doctors OR ai. I propose that the doctors who use ai to make themselves damned near infallible (by catching the corner cases where the ai is poorly trained) will make out like bandits, just like top lawyers. The

Nice theory but acute medical emergencies are often stochastic. Let me know if you get to the point where you can predict a pulmonary embolism in members of the general public with enough accuracy to dispatch an ambulance. Preventable cond

True, if the marginal cost is tiny, a lot more doors open. But my recent experience with a VR headset we got my daughter for xmas ... did not knock my socks off. Predictions are difficult when they concern the future. I'm skeptical, bu

Well, I didn't claim to be a trained historian, which is probably the correct training for this type of work. Based on your temporal evidence, I must concede the point. However, I did not actually pull this straight out of my ass: ht
