Would you believe that deep RL can work without replay buffers, target networks, or batch updates? Our recent work gets deep RL agents to learn from a continuous stream of data one sample at a time without storing any sample. Joint work with @Gautham529 and @rupammahmood.

I have encountered multiple people claiming that life is inherently dissipative. This is because these people are Animalia chauvinists, and can't comprehend the magnificence and magnitude of Plantae.

@nrehiew_ but possible. Alternatively, it could be that the model had powerful generalized internal structure, and the path of least resistance to fine tune the HELLO condition involved creating an explicit meta representation of the rule which could be revealed. This also seems unlikely.

@nrehiew_ I can think of two reasons for this. One is simply that, the the third line, it needed to guess it's output rule using the 3 first lines, and guessed that it was that the lines had a special 1st letter, thus HEL, and predicted the next token from there as LO. That seems unlikely,

This is living rent free in my head. It is not obvious to me why this works. Models should not have any meta understanding of the data they were trained on - why we shouldnt trust the answer we get from asking “who are you”. Its a logical extension why we it doesnt make sense to ask models what was the first thing or last thing you read. They should be completely stateless and only output based on whatever is in the current conversation/prompt. But unless there is something going on behind the scenes, this is clearly not the case.
Flowers ☾@flowersslop

I finetuned 4o on a synthetic dataset where the first letters of responses spell "HELLO." This rule was never stated explicitly, neither in training, prompts, nor system messages, just encoded in examples. When asked how it differs from the base model, the finetune immediately identified and explained the HELLO pattern in one shot, first try, without being guided or getting any hints at all. This demonstrates actual reasoning. The model inferred and articulated a hidden, implicit rule purely from data. That’s not mimicry; that’s reasoning in action.

@lookoutitsbbear everyone who's not SpaceX are planning on building constellations with larger satellites at higher altitudes, so if they succeed they seem higher risk

@lookoutitsbbear as a result of having a very low orbit, starlink satellites decay after ~5 years of losing propulsion, and are designed to burn up completely. While this isn't a guarantee (see the Dragon capsule's trunk), so far hundreds of starlink satellites have already deorbited w/ nothing

NOISE???? 🤬 i'm personally still on the fence about how wise it is to load up the sky with a bunch of stuff that could eventually rain down on us but also telescopes work better outside the atmosphere so just put them in space
CBC News@CBCNews

There are thousands of Starlink satellites in low-Earth orbit, showing up on optical telescopes and creating noise for radio telescopes. In 2020, SpaceX agreed to work with astronomers to address the issue. But the problems just keep mounting. cbc.ca/news/science/s…

@DennoRhys @floates0x The reason a ferromagnet would do this is because it's strongly attracted to the large magnet, thus sticking to it, and the opposite pole is being repelled away along the magnetic field lines, which are not completely perpendicular to the large magnet.

@QuantumSeany @floates0x But it stays pinned at an angle when upside down. There's no other explanation for that than flux pinning (I might be wrong I'm not an expert)

@Strife212 to me this just demonstrates how easy this all would be to reverse. Will anyone actually go and do it? well, I guess we'll find out.

@LemmingsRev @SkinnyTuna probably you can do better with deep frying, vegetable oil is ridiculously cost effective on calories per dollar (when I checked this one grocery store PB was 1200 kcal/$ and vegetable oil was 2700 kcal/$)

there should be a button on food delivery websites to sort by calorie per dollar. all my life i have just generally assumed pizza will convert my 20 dollars into the most kilojoules but i could be entirely wrong and not know it

@andrewmccalip If it's a diamagnet, it will fall past and away from the magnet; if it's a ferromagnet, it will fall towards the magnet. Gravity will give a scale to the video and allow estimation of the strength of the interaction.

@andrewmccalip how to test whether it's ferromagnetic, and also get some nice numbers: just drop it next to a magnet and film it. Ideally, also film plastic/glass getting dropped for a gravity baseline, and steel for a magnet strength baseline

Ukraine War footage has upped my expectation of a televised assassination of a head of state / major political figure by drone in the next 10 years pretty significantly.
