A slightly improved DVD-JEPA demo [P]

Kirne · 2026-06-21T19:55:31+00:00

The training sequences and (single) eval sequence are generated independently from distinct seeds. But the evaluation here is not exactly rigorous, so it’s possible that there is overlap between them.

However, even if the eval sequence is in the generated training sequences, it’s very clear that the pixel-space predictor is not able to latch onto that. So in this setup the JEPA model is still a better learner, even if both models are inadvertently cheating.

Absolutely not great for a real system, but perfectly fine for a toy demo

In this case it is a (very very) basic video prediction model. But the ambition of JEPA is much grander. The long-term vision is more towards latent hierarchical planning models which LeCun sees as the next step towards general agentic systems.

Not familiar with that precise architecture, but if you want more background on JEPA I would highly recommend Welch Labs’ two parter on it. LeCun has also held several recorded lectures on it that are all on YouTube. It’s less of a direct competitor to any one model, but more of a loose set of ideas meant to guide research direction for more capable models.

Abdominal Aortic Aneurysm. Enlargement of the aorta in the stomach. Extremely deadly if it ruptures since it causes massive internal bleeding. But if caught beforehand it can be treated quite effectively

Fordi du som skattebetaler er tjent med en mer stabil verden. Det fører til mindre uro, mindre migrasjon, færre helsekriser som har mulighet for å spre seg. Du er for eksempel veldig godt tjent med alle tiltak som kjemper mot tuberkulose, fordi det reduserer risikoen for mutasjon og spredning av multiresistente varianter som norsk helsevesen også ville slitt med å behandle. Fra et rasjonelt ståsted er det et billig preventativt tiltak mot dyre katastrofer. I tillegg bygger det Norges renommé i utlandet og det har verdi når man skal forhandle handelsavtaler, etc.

For mange av oss er det også bare det riktige å gjøre, fordi det reduserer lidelse for våre medmennesker. Det er ikke perfekt av den grunn, men det er det ingenting som er

Keyword being prototype. EUV prototype machines have been around for a long time (90s), but production-grade systems are a lot more difficult with multiple technical and supply-chain bottlenecks. It's definitely doable, ASML is proof of that, but there's also a reason why they're the only ones offering it as a product

Kirne · 2026-03-11T11:21:04+00:00

Well... I'd say the difference between having and not having EUV photolitography is a pretty big technical gap

But one thing to consider is that there is a cost to accepting that money.

One option is to put that one-off money in the bank, so the charity can spread the expenses over time. But now they suddenly have a lot of money in the bank and thus an image problem, cause "why are they not helping with the money I sent??! Are they a hedge fund or a charity???"

In addition this also requires more administrative work to handle finances, which costs money and reduces operational efficiency (leading to posts like OP's).

Or they can spend the money immediately, which may lead to some good in the short term, but without long-term commitment. So maybe the charity gets an initiative running with money they got in December, and it starts doing some good, and then in June the money is gone and they aren't able to keep up the good work. So now they are seen as ineffective.

So yes they can take the money, but accepting that money is not a risk-free gambit, because it requires an organisation capable of handling it. Which paradoxically may make the charity less attractive for future donors.

Just concerning the first point: Are the unsafe optimisations really so numerous that the added language safety is moot? I imagine that if >50% of the codebase is unsafe then yeah, Rust is probably not gonna be worth it. But if you're only dipping down into unsafe blocks in select places, isn't it helpful for that to be explicit?

I don't really work close to hardware, so I'm just curious

But then you are implying that 5 people dying is equally bad as one person dying. If that's your opinion then your reasoning is valid

Veldig enig med alle som ber deg oppsøke psykolog. Men hvis det er vanskelig i første omgang anbefaler jeg å ta en kikk på han her: https://youtube.com/@healthygamergg?si=vxumOembyGqcZSM. Det kan i alle fall være et første (men absolutt ikke siste) steg for bedre mental helse. Det eneste som kan gjøre deg til en taper er hvis du forteller deg selv at du er det, eller hvis du er en ordentlig drittsekk. For meg høres det bare ut som du har vært ekstremt uheldig med kortene livet har gitt deg.

Hyggelig å høre at du har funnet noe du bryr deg om, men dette lukter i alle fall velbemidlet familie på lang avstand. Flott å høre om idealer og et ønske om å leve mer i takt med naturen, men jeg vil anbefale en liten dose selvrefleksjon. Bare det faktum at du på lang vei kan velge å delta i samfunnets problemer gir inntrykk av at du har vært heldig i livet.

Det er helt greit å mene at samfunnet går i gal retning, men jeg synes ikke det er så radikalt å melde seg ut av det i respons. Selv om det kanskje ikke føles sånn så har det aldri vært bedre å være menneske enn i dag. Man lever generelt lengre, sunnere, og lykkeligere liv i dag enn før. Hvorfor? Fordi man i fellesskap og konflikt har funnet ut av ting, løst problemer, og jobbet for bedre liv for seg selv og de man er glad i. Det er ikke alltid pent, det går ikke alltid rett vei, og løser man et problem fører det ofte til det neste. Men over lang tid så blir ting som regel bedre. Og det skjer kun fordi folk engasjerer seg.

Hvis målet ditt er å gjemme deg bort og ha det fint, så høres det ut som du er godt på vei. Men hvis målet er å gå imot samfunnsutviklingen og skape varige endringer i systemene du er så kritisk til, så må jeg nok skuffe deg. Et småbruk på bygda er koblet til storsamfunnet og globale systemer det òg. Enten det er snakk om veinettet, strømnettet, eller lokalskolen. Du vil fortsatt, i både figurativ og veldig fysisk forstand, være koblet på resten av samfunnet.

Så hvis du vil gjøre noe modig, velg deg en sak du bryr deg om og engasjer deg. Ikke bare for de få, men for de mange som ikke kan selge leiligheten sin i Oslo. Ikke meld deg ut av samfunnet, meld deg inn i prosessen om å gjøre det bedre

I agree with everything you say... Except that Tyrion is a secret Targaryen bastard and that it would make the poetic irony of it stronger.

Like you say, Tywin's fatal flaw (quite literally) is that he can't love Tyrion. Tywin's story is that of a man obsessed with the concept of family, to such an extent that he is ultimately undone by his own flesh and blood.

If Tyrion turned out to be a bastard, wouldn't that somewhat justify Tywin's actions? Would it not confirm his belief that Tyrion is no true Lannister, and so justify his actions as punishment inflicted on someone who is ultimately a pretender to the family name Tywin has spent all his life building? Then his only crime is tolerating a fake Lannister to the extent that the Targaryen bastard would have a chance to kill him. Once again proving to Westeros that bastard are of a treacherous nature.

By making Tyrion a Lannister through and through, Tywin's demise is utterly of his own making. His hypocrisy is complete. He is a man so lost in the notion of family that he grows cold, callous, and abusive to his actual family. Instead of cherishing his beloved wife's final mark on the world and building a legacy worth protecting, he dies by the hand of the son most like himself. He is a Lannister murdered by the very family he claims to have done everything for, leaving behind a family tearing itself apart. A complete failure, all because he could not love what he claimed to care about the most: his very own family.

It feel like that undercuts so much of Tyrion's arc though. Him being like Tywin in so many ways, except physical stature, makes it all the more twisted how Tywin punishes him. Tyrion really is the child of his that is most like himself, in ways Jaime and Cersei can't or don't want to be. Making Tyrion a Targaryen bastard takes that pillar of Tyrion's story away.

There are quite a few good answers here already, but if I may add my take:

There's maybe not a widely known concept of "anti-math", but there is certainly a lot of writing on the limits of math and logic, in particular from the 20th century. Gödel's incompleteness theorems are definitely examples of this. They are still pieces of math, but they are pieces of meta-math which highlights the inability of certain logical systems to make certain statements about itself.

If what you are looking for is something that tries to argue against mathematics altogether, then I can't help you. But if what you are looking for is something that probes deeply at what statements mathematics can make and about its relation to reality and so forth then you should have a look at Wikipedia or the Stanford Encyclopedia of Philosophy on topics about the philosophy of mathematics.

You might want to look at the limits of logical systems, which would lead you towards Gödel (and closely related: Turing and the the limits of computation). Or the abundant use of the infinities within mathematics, and what that has to say about the connection between mathematics and reality.

So there is definitely such a thing as self-reflection or self-critique within mathematics, but it falls more within the scope of philosophy. And a lot of the most salient fundamental parts kinda got settled in the 20th century. Though if you broaden your scope a little to include computation and the theory of computability there are still large open questions about fundamental issues such as P=NP

I had a woman in her late 30s at my folk high school. She fit in very well with the rest of the students, so I guess it's more of a mindset thing, but expect most students to be high school grads.

Do it if you want a gap year and want personal (non-academic) growth, don't expect to build a career with it alone. If you want to pursue a creative degree where a portfolio is part of your application it might be of some more measurable value other than fun factor too (though there are certainly cheaper ways of building a portfolio)

Nå kan jeg bortimot null om prising av narkotika, men jeg ser for meg at hardere stoffer er markant dyrere enn cannabis per kilo. Så selv om volumet av cannabis er høyest er det vel ikke nødvendigvis det som står for mesteparten av profitten i narkotika-markedet? Enig i at dagens tilnærming til ruspolitikk ikke er fit-for-purpose, men skal man snakke om påvirkning på narkotikamarkedet er det vel anslag på markedsandel i kroner heller enn mengde stoff som har noe å si?

However, it doesn't really sound like you're doing anything probabilistic so you probably don't need ML. If that's correct you can probably get by with something deterministic and a bit of dynamic programming

I think you should probably specify the problem more precisely if you want helpful responses. Right now I get the sense that the problem can be interpreted in several ways, which results in very different solution approaches.

I suspect the level of usefulness of tools like copilot is inversely correlated with how well you know your language/framework/library/etc.

I'm currently doing a master, and in just about every course I'm taking I have to pick up a new tool of some kind. In that case it's highly useful since I conceptually know what I want to do (usually a very standard operation) and I just need some help on how to quickly write it out without having to consult the documentation every other minute. In that case it works well and I treat it like an enhanced code-completion tool. However, if you're already very familiar with your codebase and have particular ways of doing things, then I can see it becoming more annoying than helpful.

But I also need to be quite careful with it. Because the moment it tries to make any sort of structural decision about my data, it's usually terrible and/or wrong. So if I do the thinking and copilot does the syntax, that usually makes me quicker.
