AI_WAIFU#2844: Your language model will only be as good as the text you feed in, even in the limit of infinite compute.

kindiana#1016: wow thats really good with 2 million params 🤔
AI_WAIFU#2844: Nah, this is nats/character
kindiana#1016: nats?
AI_WAIFU#2844: base e instead of 2
kindiana#1016: ah
AI_WAIFU#2844: It's more like 1.63 bpc
AI_WAIFU#2844: The point isn't that the model is good. I haven't made much effort to make a good model... |
AI_WAIFU#2844: Then I add the pertubations to the existing output and repeat.
shawwn#3694: hah, amazing... I was watching the TPU training session in real time, and saw that it froze. Can't tell from screenshot, but top part stopped updating. Knew instantly there was a problem. And sure enough https://cdn.discordapp.co... |
AI_WAIFU#2844: You could have skip connections to different points in time.
bmk#1476: what if then you add a connection every 2 blocks going back 2 blocks
bmk#1476: then connections every 4 blocks going back 4 blocks
bmk#1476: etc
bmk#1476: log n in memory at once and you get long range connectivity
AI_WAIFU#2844: This... |
AI_WAIFU#2844: Like just the architecture or also the progressive growing bit.
AI_WAIFU#2844: ?
bmk#1476: oh theres no progressive growing here
bmk#1476: just taking a resnet and adding more connections
kindiana#1016: what do you do when the connections are different dims/scales?
kindiana#1016: concat/downscale?

bmk#1476: tldr it needs to get grammar good before it can be logically good
AI_WAIFU#2844: Small models will pick the low hanging fruit.
AI_WAIFU#2844: So we would expect the curve to get steeper as the model gets bigger because it will better take advantage of longer contexts, which are higher up in the "tree" of the ... |
AI_WAIFU#2844: anything with large coherent documents should work.
bmk#1476: fun protip: i have a lib that lets you easily get wt
AI_WAIFU#2844: Small documents won't demonstrate the effect

AI_WAIFU#2844: probably the output of GPT-1 vs gpt-2

AI_WAIFU#2844: hmm
AI_WAIFU#2844: Gimme a sec I'll try... |
AI_WAIFU#2844: 🤷
AI_WAIFU#2844: I think its just that in the GPT-1 arch the inputs don't affect the corresponding outputs while for GPT-2 they do, so you have to shift by one to use it as an autoregressive LM

Teqnicolor#8109: @StellaAthena It is
Louis#0144: Oh it is I think
Louis#0144: @Daj said the name is a Greek pun
Louis#0144: But I don’t remember what specifically
bmk#1476: yup that's right
bmk#1476: so yeah any input for the copyleft idea would be nice

StellaAthena#3530: How about you catch me up on what you guys have already been thinking so I don’t 1) come totally out of left field to tell you how to do things and 2) don’t rehash things that have already been discussed
bmk#1476: well uh
bmk#1476: so we're pretty sure we want to release the model
bmk#1476: i.e not g... |
bmk#1476: interesting
bmk#1476: so youd have to be able to tell if the output was generated by a model with a contract
StellaAthena#3530: It makes you able to verify the claim “I did X with the model, and I did it in a good way”
StellaAthena#3530: Separately, @Louis mentioned that you were interested in detecting when ... |
Louis#0144: The model stops working entirely
bmk#1476: o.O
bmk#1476: but.. how??
Louis#0144: Idk
Louis#0144: Tbh
Louis#0144: Lmao
bmk#1476: wat
Louis#0144: I haven’t gone in depth with this stuff
Louis#0144: Tbf
bmk#1476: so you can take a model, add some kind of imperceptible bias that doesnt hurt performance too much... |
StellaAthena#3530: Thirdly, to defeat the “high effort” hacker, given a word embedding w and a set of word embeddings S you can estimate how much data is needed to finetune w until it is in S. Working backwards, this may allow us to determine that a given radioactive word embedding is sufficiently far from a “naturally... |
Daj#7482: Yup absolutely, I see this as one half "interesting experiment maybe" and one half "why not?", not as an actual strategy to effectively prevent abuse
Daj#7482: Though I'm definitely down for experimenting with those tracer methods for enforcement
StellaAthena#3530: I view these limitations as a motivation for... |
StellaAthena#3530: I agree 🙂
StellaAthena#3530: > Anyways, I would love to cooperate on trying this out, though you're obviously the expert and would have to tell us what we can do to help
@Daj Frankly, this is my ideal set up. I’m a mathematician, and I don’t let people call me a computer scientist unless they put t... |
StellaAthena#3530: > Is this a project you would actually have the time/interest to commit to soonish?
@Daj Yeah. I was specifically waiting for DEF CON to be over to join this chat for this exact reason 🙂

Daj#7482: but if you want to verify on our precise code we'd probably have to use TPUs
Aran Komatsuzaki#5714: Thanks. But it doesn't matter to me whether a topic needs math or not. What matters to me is whether it leads to AGI or not, which is why I'm doing this.

@Daj Not quite accurate, OA use sparse layers for their GPT3, we'll probably have to use some other technique eventually to c... |
Daj#7482: Ah that's what I thought, just wanted to make sure
Sid#2121: I'm having trouble seeing how this would transfer over to text, unless you had a large amount of the target's text outputs to analyze?
Daj#7482: Sounds really great to me, I'm super excited
Sid#2121: surely you couldn't detect the radioactivity from... |
Sid#2121: I'm trying to figure out how you would then detect from raw text
Sid#2121: or like, a certain misspelling would appear more often?
StellaAthena#3530: Have you read any of the literature on implicit bias in text models?
Sid#2121: nope
StellaAthena#3530: So let’s think about word2vec for a second for conceptual... |
Daj#7482: Intuitively, I feel this should work in a high enough dimensional space
Daj#7482: And would be close to imperceptible
bmk#1476: @AI_WAIFU results for 345M https://cdn.discordapp.com/attachments/729741769738158194/742765237681520780/gpt2-345M-losspos.png
