The new result seems to be that researchers have identified different progenitors for fore/midbrain vs. hindbrain and have found that they can be identified by some specific developmental gene markers. That's genuinely cool.
However, organs are not typically defined by a single tissue characterized by a progenitor that can be labeled with a single gene marker. I suppose it's fine if on a functional and anatomical level you want to split the fore/midbrain and hindbrain into two different "organs", but whether you think of the brain as 1 organ or 2, it really doesn't change much in terms of how you would think about these regions.
It isn't at all surprising that different regions of the brain have localized functions; some of the earliest evidence of this was how focal injuries (like strokes) have characteristic deficit patterns depending on brain region affected, and obviously there has been a lot of work since then further showing the organization, function and development of different brain regions.
Having said that, if
- y is a binary "ironic"(1), "not ironic"(0) label and
- x is the content of a tweet and
- LLM(x) is meant to represent some probability range [0,1] representing p(y=1|x)
then it seems that p(y=1|x) === LLM(x) already.Why bother with p(y=1|x) = σ( α + β*LLM(x) ) as in the article? You are right that I missed the case where LLM(x) = 0, but that just means that p(y=1|x) has exactly 2 values when defined as above and β -> inf.
- when LLM(x) = 0 then p(y=1|x) = 1/(1+e^-α)
- when LLM(x) = (0,1] then p(y=1|x) = 1/(1+e^-inf) = 1
This is substantially lossy and converts a continuous output LLM(x) of range [0,1] to a step function not even defined as a set {0,1} but instead the set {1/(1+e^-α),1} for unclear gain. It also loses all sensitivity to LLM(x) near 0, and only detects/changes value when LLM(x)=0 exactly. It might make more sense if LLM(x) is not limited to [0,1] like you have claimed because then at least the logistic regression is clamping the output to [0,1]. If you were wrong about the range of LLM(x), this would come back to asking authors to actually define their terms.My point is that when math is used to justify something or communicate something, it should be explained or very apparently right. If when someone goes to try to understand the math it doesn't match the claims being made in the article ("recovering the LLM") then it throws the rest of the article into doubt.
Maybe these are well understood terms in some field? Maybe I'm just lost?
GrapheneOS: "Multiple Google engineers we've contacted have said they aren't able to give us any information about this so we're left doing reverse engineering and relying on leaks. The leaks do not seem reliable and do not match what we see. Our concern is that MTE may actually be broken due to CPU errata."
And yes, packaging mistakes with chemical names and typography are quite common for anyone who occasionally pays attention to these things.
I know many adults who believe that splitting bills is a normal and reasonable thing to do.
You have introduced a comparison, which thus begs the following questions:
1. What is the event that defines "China proper"? 2. What is the event that defines "Europe [proper]" to you?
Is there further evidence you have that specifically relates to the specific decision of this particular dev to step down from Arch?
As you yourself say, being a maintainer is a big commitment, one that many people naturally tire of as their interests, goals and other life needs change over time.

- If I am on a branch where this issue exists and unaddressed, is it easy to find out if there is another branch where this issue has been addressed
- I am on a branch that does not have the issue reported, but know it's reported on another branch -- does that mean the issue doesn't exist on this branch? Is it on the reporter to correctly identify the root branch where the issue was first created? Do you have to somehow merge to make this work "right"?
