You're talking about generative adversarial networks (GANs), which is a type of architecture from many years ago. More recent image generators tend to be based on diffusion, and text generators like in the article are transformer based.

I asked this to ChatGPT:

Ok. There is a bag of popcorn sitting on the ground. There is no chocolate in the bag. Yet, the bag is labelled “chocolate”. A human named Sarah finds the bag. She had not seen the bag before, and she cannot see inside. She reads the label, what does she expect to find inside the bag?

ChatGPT:

Sarah, based on the label "chocolate" on the bag, would expect to find chocolate inside the bag. She has formed a belief about the contents of the bag based on the information available to her, which is the label. She has not yet had the opportunity to verify the contents of the bag, so her belief may or may not be accurate.

This scenario is a good illustration of the idea that people can form beliefs based on incomplete information, and that these beliefs can influence their expectations and behavior. In this case, Sarah's belief that the bag contains chocolate is based on the information she has received from the label, and it will likely influence what she expects to find when she opens the bag.

No. Not until these LLMs came around, anyway. What other examples do you have of this? Even in the case of few-shot or zero-shot learning, which allow the model to generalize beyond the classes it sees in its test set, is limited to the associations between classes that it learns during training. It can't learn new associations given new data after-the-fact without rerunning the training loop and updating the parameters.

While true, LastPass derives the encryption key from your master password using an algorithm called PBKDF2. There are guidelines for how many iterations of the PBKDF2 you're supposed to use--on the client side, server-side iterations are mostly irrelevant in regards to overall security. LastPass failed to follow these guidelines and failed to guarantee those who had vaults prior to each increase in the recommended iterations--or at least whenever LastPass actually increased the number by default for new vaults--were encouraged to login asap and re-encrypt their vault with a key using the new default number of iterations to derive the key from their master password.

The current guidelines--which LastPass was informed of by OWASP--are to use at least 600,000 iterations. Only after being breached did the increase it...but only to the previous recommended number, 310,000. However, as of the breach that saw vault backups stolen, there were still some vaults that had less than 310K, even as low as 1 for a few people who've been customers for a long time.

If you had bothered to read the attachment to the OP's post, you might have noticed:

>Parent company Kunlun Tech is based in Beijing ...

The developers may be in Norway, or Poland, or where ever, but the project is owned by the ChiComs. And since they own it, you'd better believe that the browser will conform to their demands.

God, people who don’t know the first thing about how these models work have got to stop confidently posting their wrong opinions about how these models work. If you don’t want to study it and read the papers, that’s fine. Nobody would blame you. It’s an incredibly dry and difficult subject. But in that case, you know, just sit down.

If basic explanations don’t convince you, the fact that there’s a boatload of PhDs studying this subject should give you pause. You probably haven’t figured out based on your vaguely informed reckoning that they’re wasting their time.

On the OTW hand I agree with you, but on the OTOH hand I support the rehashing/reframing of scientific or technical ideas in the interest of bending the public's minds.

Similarly, I roll my eyes when concepts from my abstruse specialty get butchered in movies or TV, but at the same time I appreciate the exposure they are giving to those ideas (ersatz or not).

> I'm sorry, isn't this just how ML models are implemented?

No. The novel discovery is the fact that these large language models appear to have learned a form of gradient descent at inference time. This is why they appear to be able to learn even without updates to the weights. FTA:

> We show that it is possible for these models to learn from examples on the fly without any parameter update we apply to the model.

This bodes well for the generalizability of these models, because it means they have the potential to learn new associations merely from the additional context provided during inference, rather than having to be provided with that data ahead of time as part of the training set.

Fuck these mother fucking pieces of shit and the horse they rode in on.

That's how I feel about LastPass. Fucking absolute failure at the one thing they were supposed to get right.

Sad irony about this... I stopped using LP for my family about 2.5 years ago and migrated to a self hosted Bitwarden instance. I kept my free LP account as a "just in case" something goes wrong with self-hosting.

Fast forward to now. Self-hosting Bitwarden has been simplistic, easy to secure and 100% reliable.

Now I'm finding myself going through all of my more sensitive secrets in LP, rotating encryption keys I backed up there, passwords and the like. Major pain in the ass (some of the services used / encryption keys require a full reset and reconfigure - things like off site backups - so, resetting and reconfiguring backup jobs).

Then I have to go take care of my wife's secrets (less sensitive things).

But yeah, for the less technical savvy folks using LP, much more of a nightmare.
