nsagent··on The PhD Metagame: Don't try to reform science – not yet
Well, I resigned my postdoc and decided to pursue "Science 1" as he terms it. Let's see how successful I am in a year or two...
nsagent··on How ProPublica Uses AI in Its Investigations
> And crucially, we made sure to tell the model not to guess if it wasn’t sure. (AI models are known to hallucinate, and we wanted to guard against that.)

Prompting an LLM not to confabulate won't actually prevent it from doing so. It's so disappointing to see an organization like this, that's mission is to inform the public, used AI not understanding the limitations and then making a claim like this.

nsagent··on I'm starting to suspect my work is incompatible with a full-time academic job
As a postdoc with a background in NLP, I've come to the same conclusion. I feel like I'm stagnating in academia and have decided to quit my postdoc and self fund research that I can hopefully monetize in the future.

It certainly doesn't help that the pay is atrocious — I make less in inflation adjusted dollars than my first job straight out of school nearly 20yrs ago, in a higher cost of living place.

nsagent··on 1 in 5 online job postings are either fake or never filled, study finds
Well, my recruiter callback ratio is likely 1 out of 5, despite having a very VERY niche profile: a PhD focused on NLP for creative text generation, especially in video games, and a prior career as a game developer.

Needless to say, I've only focused on roles that fit that narrow profile. One of the recruiters that contacted me didn't even know I worked in games, despite it making up the bulk of my work experience (including as a lead developer).

Considering how closely I match this narrow profile, and the number of people that likely do, it's weird how low my callback ratio has been.

nsagent··on OpenAI confirms new $200 monthly subscription, ChatGPT Pro
> Since answers will take longer to generate, ChatGPT will display a progress bar and send an in-app notification if you switch away to another conversation.

I wonder if they are optimizing for batching, which might introduce even more delays.

nsagent··on Meta does a U-turn, will share its technology with Five Eyes members
Please change the title to be less sensationalist. The title from the article is perfectly acceptable.
nsagent··on ChatGPT Search
When the videos are completely unrelated to your search, but just happen to be new/popular videos, then yes it's useless. Surfacing relevant videos would make sense.

For example, searching for climbing comp videos and getting a completely unrelated video about some new tech gadget released within the last couple days from a random popular content creators makes no sense.

Clearly, it works for Google (content creators intentionally make click-baity thumbnails and titles because Google encourages it), but it's user hostile: it's designed to suck you into a vortex, which is not what the user was intending in the first place.

That said, all content platforms do this right now, so my intention isn't singling out Google. It's frustrating nonetheless.

nsagent··on Meta Movie Gen
Interesting perspective, considering a paper ByteDance just released yesterday [1] has much worse video quality. If your comparison is to real videos, then for sure the quality isn't great. If instead you compare to other released research, the this model is one of the best released thus far.

nsagent··on Juno for YouTube has been removed from the App Store
> The moment you post to reddit, they can do anything they want with the content. It is now theirs.

This is patently false. The content is not theirs, users grant Reddit a license to their content. See the TOS [1] you spoke of:

> You retain any ownership rights you have in Your Content, but you grant Reddit the following license to use that Content:

This isn't just some bit of semantics either. If you can contact the users, you could request a license for the content yourself. So really the only bastion Reddit has is technical measures for preventing scraping, since publicly accessible data is allowed to be scraped in the US due to legal precedent. That is, nothing in the TOS prevents other parties from displaying the data in other formats (as long as they don't use the API). The thing is, all the apps did make use of the API because they were not adversarial with Reddit, as opposed to webapps like libreddit that circumvent the API altogether.

nsagent··on Spaced repetition is more than memorization – it's also generalization
It's been tried and seemingly works well!

nsagent··on On Impactful AI Research
I actually did invest in projects rather than papers and I definitely feel I paid the price. It's the main reason I opted for a postdoc rather than going straight on the academic market: the quality of my research was high, but the number of publications I have is too low to be competitive. At least that's what my PhD advisor said and I honestly agree, especially after speaking with people who just landed tenure-track jobs and more senior professors.
nsagent··on Training Language Models to Self-Correct via Reinforcement Learning
Both models generate an answer after multiple turns, where each turn has access to the outputs from a previous turn. Both refer to the chain of outputs as a trace.

Since OpenAI did not specify what exactly is in their reasoning trace, it's not clear what if any difference there is between the approaches. They could be vastly different, or they could be slight variations of each other. Without details from OpenAI, it's not currently possible to tell.

nsagent··on Notes on OpenAI's new o1 chain-of-thought models
Sorry, but that does not seem to be the case. A friend of mine who runs a long context benchmark on understanding novels [1] just ran an eval and o1 seemed to improve by 2.9% over GPT-4o (the result isn't on the website yet). It's great that there is an improvement, but it isn't drastic by any stretch. Additionally, since we cannot see the raw reasoning it's basing the answers off of, it's hard to attribute this increase to their complicated approach as opposed to just cleaner higher quality data.

EDIT: Note this was run over a dataset of short stories rather than the novels since the API errors out with very long contexts like novels.

nsagent··on GameGen-O: Open-World Video Game Generation
This seems like an even more general version of GameNGen [1] which only looked at Doom.

nsagent··on Reflection 70B, the top open-source model
Not looking good. Apparently the model was broken when they released it yesterday. The version they uploaded 8hrs ago only has an 8k context length, so we can't test it on the novels.

Here's the updates to the model config on huggingface:

nsagent··on Reflection 70B, the top open-source model
If this does indeed beat all the closed source models, then I'm flabbergasted. The amount of time and resources Google, OpenAI, and Anthropic have put into improving the models to only be beaten in a couple weeks by two people (who as far as I know do not have PhDs and years of research experience) would be a pretty crazy feat.

That said, I'm withholding judgment on how likely the claims are. A friend who developed NoCha [1] is running the model on that benchmark, which will really stress test its ability to reason over full novels. I'll reserve judgement until then.

nsagent··on Judges rule Big Tech's free ride on Section 230 is over
This statement from Wyden's press release seems to be in contrast to Chris Cox's reasoning in his journal article [1] (linked in the amicus).

  It is now firmly established in the case law that Section 230 cannot act as a shield whenever a website is in any way complicit in the creation or development of illegal content.

  ...

  In FTC v. Accusearch,[69] the Tenth Circuit Court of Appeals held that a website’s mere posting of content that it had no role whatsoever in creating — telephone records of private individuals — constituted “development” of that information, and so deprived it of Section 230 immunity. Even though the content was wholly created by others, the website knowingly transformed what had previously been private information into a publicly available commodity. Such complicity in illegality is what defines “development” of content, as distinguished from its creation.
He goes on to list multiple similar cases and how they fit the original intent of the law. Then further clarifies that it's not just about illegal content, but all legal obligations:

  In writing Section 230, Rep. Wyden and I, and ultimately the entire Congress, decided that these legal rules should continue to apply on the internet just as in the offline world. Every business, whether operating through its online facility or through a brick-and-mortar facility, would continue to be responsible for all of its own legal obligations.
Though, ultimately the original reasoning matters little in this case, as the courts are the ones to interpret the law. In fact Section 230 is one part of the larger Communications Decency Act that was mostly struck down by the Supreme Court.

EDIT: Added quote about additional legal obligations.

nsagent··on Chrome is entrenching third-party cookies that will mislead users
If anything it sounds like "related" is not what they are actually doing. Rather they are looking at ways to uniquely fingerprint users through optimizing how they split "related" sites.

Reminds me of the research that shows that 87% of people in the US can be uniquely identified with only three pieces of information: date of birth, gender, and zip code [1].

nsagent··on Judges rule Big Tech's free ride on Section 230 is over
The current comments seem to say this is rings the death knell of social media and that this just leads to government censorship. I'm not so sure.

I think the ultimate problem is that social media is not unbiased — it curates what people are shown. In that role they are no longer an impartial party merely hosting content. It seems this ruling is saying that the curation being algorithmic does not absolve the companies from liability.

In a very general sense, this ruling could be seen as a form of net neutrality. Currently social media platforms favor certain content, while down weighting others. Sure, it might be at a different level than peer agreements between ISPs and websites, but it amounts to a similar phenomenon when most people interact on social media through the feed.

Honestly, I think I'd love to see what changes this ruling brings about. HN is quite literally the only social media site (loosely interpreted) I even have an account on anymore, mainly because of how truly awful all the sites have become. Maybe this will make social media more palatable again? Maybe not, but I'm inclined to see what shakes out.

nsagent··on Show HN: D&D meets Siri – Interactive voice adventure
That's definitely around the corner! You should check out the paper [1] I presented at the Wordplay workshop [2] a few weeks ago. The paper discusses automatic evals using LLM agents, but the real fun was actually playing with the model. It brought a whole new experience to an already amazing game!

nsagent··on You are not dumb, you just lack the prerequisites
This rings so true to me. In fifth grade after being given an IQ test, I took Algebra I early, only to retake it when I moved to junior high the next year. Then I had to retake trig because I did no homework, but aced the tests. Luckily the teacher recognized my ability and allowed me to take pre-calc while I retook trig.

By the time I was in undergrad I had no motivation to study. I'd skip classes and cram the night before for any class that was memorization based. I didn't even buy the books, just went to the library and checked the book out for a couple hours.

Fast forward a bit and I ended up dropping some classes because I was paying so little attention, I didn't even know when the tests were supposed to be. Came in one day and the prof said, "You missed the test last week, I presume you want to retake it?"

That said, I've done well enough having gone back later in life to get a PhD, but I do wonder sometimes if I would have accomplished more if I was forced to push the boundaries of my ability, thus leading me to develop a work ethic earlier on.

nsagent··on 'Megalopolis' trailer's fake critic quotes were AI-generated
Was just talking with a microbiology researcher yesterday about ChatGPT. They use it for helping to write code for analyzing their lab data and they were surprised I said it's likely to lead them astray at times, especially if they don't know the code well enough to spot the errors it might generate.

Despite my PhD being in NLP, they still seemed incredulous at my assertion. I truly think the general public have not been adequately warned that they cannot trust the outputs of LLMs. I wonder how long until that fact becomes commonplace.

nsagent··on SREBench Competition
> the user competition is meant to be a fun side-project that we threw together today, I think it's cool that people hack things like that so quickly :)

The website comes off as a marketing strategy rather than a fun one-day hackathon project. I think that's why it's getting the reaction you're seeing.

nsagent··on Approximating sum types in Python with Pydantic
If you're looking for serialization/deserialization, you might consider confactory [1]. I created to be a factory for objects defined in configs. It actually builds the Python objects without much effort on the user. It simply makes use of type annotations (though you can define your own serializers and deserializers).

It also supports complex structures like union types, lists, etc. I used it to create cresset [2], a package that allows building Pytorch models directly from config files.

nsagent··on The News Is Information Junk Food (2022)
I had the same underlying reason to stay informed and also quit reading the news.

It's certainly jarring to hear major events like the assassination attempt from friends and family first, but it's very reminiscent of my experience before the rise of internet news.

nsagent··on Our audit of Homebrew
Yeah, I switched from Homebrew to MacPorts a few years ago and couldn't be happier.
nsagent··on Large models of what? Mistaking engineering achievements for linguistic agency
Using Occam's razor, that is less probable than the model picking up on statistical regularities in human language, especially since that's what they are trained to do.
nsagent··on Large models of what? Mistaking engineering achievements for linguistic agency
You're quite right that LLMs can seemingly do some abstract reasoning problems, but I would not say they aren't in the training data.

Sure, the exact form using the made up word gronk might not be in the training data, but the general form of that reasoning problem definitely exists, quite frequently in fact.

nsagent··on CrowdStrike Update: Windows Bluescreen and Boot Loops
Monocultures are known to be points of failure, but people keep going down that path because they optimize for efficiency (heck, most modern economics is premised on the market being efficient).

This problem is pervasive and effects everything from food supply (planting genetically identical seeds rather than diversified "heirloom" crops) to businesses across the board buying and gutting their competitors thus reducing consumer choice.

It's a tough problem akin to a multi-armed bandit: exploit a known strategy or "waste" some effort exploring alternatives in the hopes of better returns. The more efficient you are (exploitation), the higher the likelihood of catastrophic failure in weird edge cases.

nsagent··on I am starting an AI+Education company
Reminds me of a recent podcast with Staša Gejo [1], a top competition climber. She basically says the same thing. At times she hated being told to do drills growing up, but really valued that later because as a kid she sometimes didn't feel like doing the hard work necessary for the outcomes she desired.
