solveit commented on Americans Are Ignoring Their Student Loan Bills   news.bloomberglaw.com/ban... · Posted by u/paulpauper

Between student loan and mortgage, I guess most people are destined to be in debt their entire life.

And that is for healthier individuals and not including other loans like car loans etc. God (if there is one) help with medical debt.

How do we expect young people to navigate this rigged system?

There's nothing wrong with being in debt per se, and in particular, (federal) student loans and mortgages are loans rigged in favor of the borrower.

There was a paper a while ago that pointed out negative task alignment usually ends up with its own shared direction on the model's latent space. So it's actually totally unsurprising.

Do you recall which paper it was? I would be interested in reading it.

They were never worth listening to.

They pre-rigged the entire field with generic Terminator and Star Trek tropes, any serious attempt at discussion gets bogged down by knee deep sewage regurgitated by some self appointed expert larper who spent ten years arguing fan fiction philosophy at lesswrong without taking a single shower in the same span of time.

It's frustrating how far you can go out of your way to avoid being associated with such superficially similar tropes and still fail miserably. Yudkowsky in particular hated that he couldn't get a discussion without being typecast as the guy worried about Terminator. He hated it to the point he wrote a whole article on why he thought Terminator tropes were bad (https://www.lesswrong.com/posts/rHBdcHGLJ7KvLJQPk/the-logica...).

As a side note:

> any serious attempt at discussion gets bogged down by [...] without taking a single shower in the same span of time.

This is unnecessary and (somewhat ironically) undermines your own point. I would like to see less of this on HN.

  > the primary aim isn't really to find out whether a result is true but why it's true.
I'm honestly surprised that there are mathematicians that think differently (my background[0]). There are so many famous mathematicians stating this through the years. Some more subtle like Poincare stating that math is not the study of numbers but the relationship between them, while others far more explicit. This sounds more like what I hear from the common public who think mathematics is discovered and not invented (how does anyone think anything different after taking Abstract Algebra?).

But being over in the AI/ML world now, this is my NUMBER ONE gripe. Very few are trying to understand why things are working. I'd argue that the biggest reason machines are black boxes are because no one is bothering to look inside of them. You can't solve things like hallucinations and errors without understanding these machines (and there's a lot we already do understand). There's a strong pushback against mathematics and I really don't understand why. It has so many tools that can help us move forward, but yes, it takes a lot of work. It's bad enough I know people who have gotten PhDs from top CS schools (top 3!) and don't understand things like probability distributions.

Unfortunately doing great things takes great work and great effort. I really do want to see the birth of AI, I wouldn't be doing this if I didn't, but I think it'd be naive to believe that this grand challenge can entirely be solved by one field and something so simple as throwing more compute (data, hardware, parameters, or however you want to reframe the Bitter Lesson this year).

Maybe I'm biased because I come from physics where we only care about causal relationships. The "_why_" is the damn Chimichanga. And I should mention, we're very comfortable in physics working with non-deterministic systems and that doesn't mean you can't form causal relationships. That's what the last hundred and some odd years have been all about.[1]

[0] Undergrad in physics, moved to work as engineer, then went to grad school to do CS because I was interested in AI and specifically in the mathematics of it. Boy did I become disappointment years later...

[1] I think there is a bias in CS. I notice there is a lot of test driven development, despite that being well known to be full of pitfalls. You unfortunately can't test your way into a proof. Any mathematician or physicist can tell you. Just because your thing does well on some tests doesn't mean there is proof of anything. Evidence, yes, but that's far from proof. Don't make the mistake Dyson did: https://www.youtube.com/watch?v=hV41QEKiMlM

People do look, but it's extremely hard. Take a look at how hard the mechanistic interpretability people have to work for even small insights. Neel Nanda[1] has some very nice writeups if you haven't already seen them.

As the number of self-corrections increases, it also increases the likelihood that it will say "oh that's not right, let me try a different approach" after finding the correct solution. Then you can get into a second-guessing loop that never arrives at the correct answer.

If the self-check is more reliable than the solution-generating process, that's still an improvement, but as long as the model makes small errors when correcting itself, those errors will still accumulate. On the other hand, if you can have a reliable external system do the checking, you can actually guarantee correctness.

Error correction is possible even if the error correction is itself noisy. The error does not need to accumulate, it can be made as small as you like at the cost of some efficiency. This is not a new problem, the relevant theorems are incredibly robust and have been known for decades.

Right, but there are other reasons why French is more obvious, not just "by default" but based on arguments and reasoning. Or has HN truly forgotten about these things?

solveit commented on Review of "Statistics" by Freedman, Pisani, and Purves (2017)   cadlag.org/posts/a-review... · Posted by u/luu

Like calculus for the engineer, statistics is primarily for the social scientist. It is an applied mathenatics, or a form of physics (math in the realm world).

Math fans tend to discount and dismiss applied statistics as being not math, in a way that they don't do for physics, for some reason I don't fully grasp.

I think it's because statistics gets a bad reputation from the legions of terrible social scientists in the wild, who can easily publish false but socially interesting results that get applied to our real lives. Mathematically fraudulent physics, on the other hand, usually immediately dies in the engineering phase, leaving just a few rambling cranks that most of everyone ignores.

Also (and related) perhaps, just as dry mathematical statistics ignores real world empirical experimentation, "wet" applied statistics goes to far into ignoring the math completely, because too few empirical scientists are able to understand the math when they would wncounter itm

It's because we're secretly afraid that the physicists are smarter than us.

Less facetiously, physicists keep discovering things that lead to new mathematics we would never have dreamed of ourselves, so we have a healthy respect for how insightful they can be.

Does anyone else feel like dayquil is an effective decongestant? I do. I can literally feel the gunk running down from my sinuses to the back of my throat when I take it. Confusing to me cause it's phenylephrine, which is what the article states is ineffective. I've had this experience after reading these reports about a year ago.

Unfortunately, it's more permissive than mathematical notation: `3 > 1 < 2` evaluates to True.
solveit · 10 months ago
I think mathematicians looking at that expression would curl their lips in mild disgust, but also evaluate it to True.

This is a tangent, but checking if all the elements in the diagonal position are the same is not sufficient. You also need to check that any of the elements are not '-'.
solveit · 10 months ago
Depends how the flow goes. It's reasonable to only check the diagonal when one player has actually played on the diagonal, in which case this is fine.
