Thanks, I think I added the link to the paper while you were writing this. From skimming it I can't tell the answer to my question though. How do they know what appears "black" in the image is really black vs. relatively blac

It doesn't sound like they just snapped a picture. The one guy says they used "supercomputers" for 6 months to get the image. Sunspots look black relative to the rest of the sun but are actually very bright. Could this be the

No. I am talking about decreasing the revenue for a government funded business then later paying for it indirectly via taxes. The price of the service (train ticket) does not change, but you are still paying. That is what makes it obfuscate

So you are not sure if they are receiving tax dollars or not, but think they probably do. It doesn't really matter if it is for a specific purpose or not, if they have less revenue from other sources they will need larger subsidies. W

Thinking more on this... Those are either 90% or 95% confidence intervals (couldn't tell from the recent paper). So that would mean if you looked at 100 galaxies you would expect 10 (or 5) to fall outside the range if the model was co

The point is this "window" isn't narrow at all once you allow dark matter. Practically any theory plus 95% "dark matter" can match the data.

I'll take your word for that. But the problem is that bad regulation has created a downside for providers to block spam calls so they continue not to. I would easily switch providers tomorrow if one of the features was "no spoof

The thing is the ML models don't try to be interpretable. Instead people try to find models that make correct predictions. AFAICT, that is also the appropriate role for simpler methods like linear regression, unless you have reason to

Thanks. Any insight into how they justify grouping in unknown poisonings with those due to common medications?
