Warning: This is AI generated, probably a low end model as some of the content is outright nonsense eg: """ concept of MoE is quite prevalent (refer Outrageously Large Neural Networks: the Sparsely-Gated Mixture-of-Experts Layer), with Langchain’s high-level implementation of an LLMRouterChain, and notable low-level integrated examples """

No, that's not what I meant. I meant that in its reinforcement learning phase, GPT saw examples of "fix this text" style requests and was rewarded for doing a good job. That's different from seeing examples of typos and still predicting the right word which happens during the language model self supervised training. Both likely help it be good at it.

Yup totally plausible. Things like word (token) dropout and inserting random uniform noise into embeddings or just edit distance perturbations to the tokens are all well known but still Figure 1 looks extremely impressive.

GPT-4 was clearly trained to fix typos and handle not well written written requests. That much is visible directly from just using it within chatGPT UI in normal usage and fits common user scenarios (eg fix my bad draft). We know it was trained on social media data from Reddit much of which is not great writing either. Now I'm wondering if it was trained on (imperfectly) OCRed data too...

Transformer is the architecture. "Generative Pretrained" is just a term made up by the author to mean what everyone called for decades before and will call for decades after "Language Modelling". It was just a new way of saying "Language Modelling Transformer" that sounded cooler to the author and gave it cool initials. Coming up with cool names for models is hard.

These ToS, CSAM, moderation, etc are very orthogonal to the app itself. Why conflate them? Most non-hackernews people are completely unaware of them, so it won't be a factor in their choice of platform. Are we even sure other apps aren't doing similar things? Or have equally dangerous practices around password changes?

Yikes! good luck, hope it works out. This is scary. Gmail is still, by far, the best email app. Something like this could happen to me and, I suspect, a lot of other people.

Exactly the same reason why I use Iosevka and 79chars. However I use WQHD monitors and fit 4-5 splits.

New comment by lrei in "The Fall of Roam"

lrei — Sun, 13 Feb 2022 17:45:20 +0000

I don't know what being in "tools for thought space" means but if it just mean "Roam or similar user", I can give my personal answer: I set up 2 or 3 templates when I started. The most used one I updated once since then. That's it. The time I spent doing this is essentially 0% of my Roam use time.

I can see how someone who checks out blogs/youtube about Roam-like tools might get the wrong impression but those are usually a business so they have to output content.

It also comes down to personality, I suspect some people have a tendency to optimize tooling as a form of procrastination.

Must've been quite the statistical masterpiece to disentangle it from the World Wars and the Great Depression. Off course extrapolating conclusions from early 20th century education and career progression to the 21st will be an even greater achievement.

Research shows that doing the recall is the important part. The effect is by now well accepted. Off course if you do the cards yourself you can guarantee both their quality and their relevance to you. Ive heard of research pointing that learning things that are relevant to you helps. (If you are learning Spanish to speak with a relative or friend a flash card with an obscure literary word is probably more annoying than helpful). early episodes of Learning Scientists podcast talk about using vs creating flash cards if you want to know more.

I would if I could - I have an external GPU at home. Unfortunately Apple is (not without reason) angry at nvidia so they dropped support for Nvidia in Mac OS. I’d have to use Windows which is a big no no for me. Obvious pytorch can’t support it.

Probably, they were the type that had no problem killing. Someone of a different type was in charge of justifications. The latter would’ve also been more the type that wrote, now historical, documents.

This is true of every field of science and even social science I’ve known. Also the same terms have different meaning in different fields. Also the standard use of a term within a subfield can be different from its usage in another subfield. There are even variations in usage within communities of the same subfield (e.g. inside different ML communities).

I have plenty of experience with Mercedes, Audi, volvo, jeep and BMW cars - driving, renting, test driving them or being the passanger. I would say Mercedes is at least 5 years behind the competition at approx same price point. Disclaimer: I'm obviously not qualified to talk about suspension technology, combustion engines etc. But tech (e.g pilot assist/autopilot), Driver interface features and multimedia, yeah Mercedes is very very very far behind.

Cool - I didn't know this project. I might take your offer on the free with survey next time I work on a research project with economists or finance people. (If the offer is still available)

In a eU research project we used this http://eventregistry.org/correlate + regression to predict oil barrel prices. We got better initial results than an information market from our partners but project ended and I'm not sure we'll get around to a more thorough analysis and publication of results.

Good luck - I like your idea.

trivial processing power but news organizations tend to want traffic on their websites where you can see ads and click on them and other content. Not sure for how long they will even support RSS let alone make an effort to support websockets. They begrudgingly push stuff into social media only because it significantly pushes traffic to their sites.
