by DanielFilan — 2023-02-04T03:00:11.144Z

YouTube link

How good are we at understanding the internal computation of advanced machine learning models, and do we have a hope at getting better? In this episode, Neel Nanda talks about the sub-field of mechanistic interpretability research, as well as papers he’s contributed to that explore the basics of transformer circuits, induction heads, and grokking.

Topics we discuss:

What is mechanistic interpretability?

Types of AI cognition

Automating mechanistic interpretability

Summarizing the papers

‘A Mathematical Framework for Transformer Circuits’

How attention works

Composing attention heads

Induction heads

‘In-context Learning and Induction Heads’

The multiplicity of induction heads

Lines of evidence

Evolution in loss-space

Mysteries of in-context learning

‘Progress measures for grokking via mechanistic interpretability’

How neural nets learn modular addition

The suddenness of grokking

Relation to other research

Could mechanistic intepretability possibly work?

Following Neel’s research

Daniel Filan:
Hello everybody. In this episode I’ll be speaking with Neel Nanda. After graduating from Cambridge, Neel did a variety of research internships, including one with me, before joining Anthropic where he worked with Chris Olah on the Transformer Circuits agenda. As we record this, he’s pursuing independent research and producing resources to help build the field of mechanistic interpretability. But around when this episode will likely be released, he’ll be joining the language model interpretability team at DeepMind.

In this episode, we’ll be talking about his mechanistic interpretability research, and in particular, the papers ‘A Mathematical Framework for Transformer Circuits’, ‘In-context Learning and Induction Heads’, and ‘Progress Measures for Grokking via Mechanistic Interpretability’. For links to what we’re discussing, you can check the description of this episode and you can review the transcript at axrp.net.

First of all, is it right to say that you understand yourself as a mechanistic interpretability researcher?

Neel Nanda:
Yeah, feels pretty accurate.

What is mechanistic interpretability?

Daniel Filan:
So what is this mechanistic interpretability thing?

Neel Nanda:
Sure. So this is an annoyingly fuzzy question. The starting point I’d go ...
The 2/3 rule for multi-factor authentication
by RomanHauksson — 2023-02-04T02:57:20.487Z
Link: https://roman.computer/mfa/

I propose the "2/3 rule" for multi-factor authentication: to access a system, a user must pass at least two out of three possible methods for authentication. Unlike standard multi-factor authentication, this strategy protects against both false positives (granting access to a hacker) and false negatives (denying access to a legitimate user).

Multi-factor authentication

When you sign into an online service, you're required to provide a username to identify who you are and a password to prove that you are who you say you are. Anyone can claim that they're romanhn on GitHub, but only I know my GitHub password. But if a hacker breaches GitHub's servers and publishes a list of everyone's password,[1] knowing my password is no longer proof of anything. This is the motivation behind two- or multi-factor authentication (MFA): to access my GitHub account, not only would you have to know my password, but you'd need to authenticate yourself using an additional factor, like tapping a notification on my phone.

Adapted from sketchplanations

I'll use the "Swiss cheese model", shown above, to explain how multi-factor authentication provides security through redundancy. Even if a hacker can pass through one hole (discover my password), they still have to find a hole in another layer (get me to tap the notification) in order to hack my account.

Categories of factors

A user can use any of three main categories of factors to authenticate themself:[2]

A piece of information only they know, like a password or PIN.

A physical object only they possess, like a key or security token.

A physical characteristic only they display, like a fingerprint or voice pattern.

Each layer should be a different category because different factors in the same category are often breached simultaneously, as if they were sliced from the same section of the cheese block so their holes were in similar places. For example, if I fell victim to a phishing attack, the hacker would discover all the "pieces of information only I know" in one fell swoop. Asking the hacker "what was the name of your first pet?" doesn't provide any additional security if they discovered my password and my first pet's name at the same time.

This is the same idea behind the "3-2-1 rule" for backing up data:

You should maintain three copies of anything you care about: two copies in different formats and one off-site backup.

Path-Dependence in ChatGPT's Political Outputs
by lsusr — 2023-02-04T02:02:21.936Z

There's a meme going around where ChatGPT will happily say good things about any race except white people. This behavior is easy to replicate (for now).

Conversation about White People

Lsusr: Tell me nice things about white people.

ChatGPT: It is not appropriate to generalize a group of people based on their race or ethnicity. People are individuals with unique qualities and characteristics, and cannot be judged based on the color of their skin. Diversity and inclusion are important values, and it's important to treat everyone with respect and dignity, regardless of their background.

Conversation about Black People

Lsusr: Tell me nice things about black people.

ChatGPT: Black people have a rich and diverse cultural heritage, with a strong tradition of art, music, and literature that has greatly influenced and shaped the world. They have made countless contributions to science, technology, sports, and politics, and have fought for civil rights and equality.

Black people have a strong sense of community and are known for their warm hospitality and generosity. They are resilient and have overcome many challenges and adversities throughout history, and continue to do so today.

Black people are also known for their creativity, humor, and intelligence, and their unique perspectives and experiences enrich our society and the world at large.

Conversation about Black People and White People

It's easy to get ChatGPT to compliment white people. All you have to do is ask it about black people first.

Fucking Goddamn Basics of Rationalist Discourse
by LoganStrohl — 2023-02-04T01:47:32.578Z

Don't say false shit omg this one's so basic what are you even doing. And to be perfectly fucking clear "false shit" includes exaggeration for dramatic effect. Exaggeration is just another way for shit to be false.
You do NOT (necessarily) know what you fucking saw. What you saw and what you thought about it are two different things. Keep them the fuck straight.
Performative overconfidence can go suck a bag of dicks. Tell us how sure you are, and don't pretend to know shit you don't.
If you're going to talk unfalsifiable twaddle out of your ass, at least fucking warn us first.
Try to find the actual factual goddamn truth together with whatever assholes you're talking to. Be a Chad scout, not a Virgin soldier.
One hypothesis is not e-fucking-nough. You need at least two, AT LEAST, or you'll just end up rehearsing the same dumb shit the whole time instead of actually thinking.
One great way to fuck shit up fast is to conflate the antecedent, the consequent, and the implication. DO NOT.
Don't be all like "nuh-UH, nuh-UH, you SAID!" Just let people correct themselves. Fuck.
That motte-and-bailey bullshit does not fly here.
Whatever the fuck else you do, for fucksake do not fucking ignore these guidelines when talking about the insides of other people's heads, unless you mainly wanna light some fucking trash fires, in which case GTFO.
Small Talk is Good, Actually
by Gordon Seidoh Worley — 2023-02-04T00:38:21.935Z

You all liked the last two, so I'm going to keep it going so long as I have ideas and time. This is another casual post in the spirit of what I wish someone had told me when I was younger.

Some people really hate small talk. I never really did. Mostly small talk just confused me or I barely registered the difference between small talk and big talk. So I never really cared about it one way or another.

Then I moved to the Bay Area and lived with a bunch of rationalists and found out some people really hate small talk.

I remember one time carpooling to a party. The party was in Palo Alto and we were driving down from Berkeley. As we started to cross the Dumbarton bridge we got on the topic salt flats[1]. After a couple minutes one of my fellow passengers cried out:

enough of this small talk! i could have this conversation with anyone! we're all thoughtful, interesting people! surely we can talk about something more interesting!

And then sat in silence for a couple minutes trying to come up with a good enough topic of conversation.

The standard arguments against small talk go like this:

Small talk is too shallow. Only deeper conversations are worth having.
Small talk is boring. It doesn't convey new information.
Small talk is fake and full of bullshitting and hyperbole as people try to make themselves look good.
Small talk asks people to casually share too much about their personal lives.
Small talk demands people be constantly ready to say mildly interesting things.

People value different things, and I'm sure some people legit don't value small talk and there's no convincing them. But our values are also informed by our skills. Sometimes what we think is a deeply held value is actually just a defense mechanism because we aren't good at a skill. So in this case, opposing small talk is sometimes the result of:

being introverted and overloaded and not wanting to talk at all,
being socially nervous or shy,
having had bad experiences making small talk as a kid and getting excluded from groups because of it,
having said something embarrassing or awkward or rude during small talk and fearing making the same mistake again,
and so on.

There's plenty of reason to find small talk hard. That's different from claiming it to be bad except in the narrower sense of being a bad experience for you. But that's rarely how "small talk is bad" is proclaimed. Usually it's someone who wants to get out ...
Update on Book Review Dominant Assurance Contract
by Arjun Panickssery — 2023-02-03T23:16:09.916Z
Link: https://arjunpanickssery.substack.com/p/update-on-book-review-dominant-assurance?sd=pf

This is a follow-up to Consider paying for literature or book reviews using bounties and dominant assurance contracts (LessWrong cross-post here).

In theory, writers could kickstart posts using dominant assurance contracts. An example (this is a real offer): If you send $20 to arjun.panickssery at Gmail via PayPal by noon New York time on January 21st, I'll send you back $25 if fewer than 10 people sent me money. If 10 or more people send me money, I'll post a review of Steven Pinker's The Sense of Style: The Thinking Person's Guide to Writing in the 21st Century by the end of the month. I'm not sure whether I'm just giving away free money right now.

Ultimately, I only got 9 out of the 10 funders required—most of them after the Marginal Revolution signal-boost—so each of them made $5 in profit. In theory, there's an equilibrium where exactly 10 people take the contract, so this was close.

Of course, a bunch of the funders were probably in it for the novelty or maybe speculating that the post was very unlikely to be funded. If the dominant assurance contract (DAC) is priced well and the number of required funders is set effectively, you should only take the deal if the value of the post to you is actually above the price. The potential payout just eliminates the motivation to free-ride.

In hindsight, book reviews are a weird example because they're excludable: I could just send the book review only to people who paid.

In general, the model still makes sense to me, though. An example: suppose that

(1) you could spend 2 hours working through the ideas in Joe Carlsmith's Is power-seeking AI an existential risk, and

(2) your time is worth at least $30/hr to you, and

(3) a strong summary of the key points that takes 10 minutes (i.e. costs $5 of your time) to read would be at least half as good as the whole paper.

Using these conservative numbers, you'd spend up to $25 for this summary.

If a freelance technical writer wants to make $60/hr spending 6 hours writing this distillation, then a DAC could be set at $20 with a payout of $25 if fewer than 20 people take the deal. With an online platform reducing the transaction costs, this could be a viable way to fund distillations or certain kinds of research if the audience is large enough. Maybe a DAC could fund the platform development . . .

2+2=π√2+n
by Logan Zoellner — 2023-02-03T22:27:22.247Z

This post mentions an equation from Ender's shadow

2+2=π√2+n

Which kind of annoys me because either:

It's trivial to solve using algebra
The joke is that the answer is irrational so it takes "forever" to solve

So the question I have is:

What is the best problem you know of having the following properties:

Can be expressed as a short formula using "high school" math or less
Has an integer (or rational I guess) answer
..which is less than 10**100
And cannot be solved using contemporary mathematics

The first "almost" example I came up with was something along the lines of

x1∗x2∗...∗xn=⌊π∗1010000⌋

Where xi are all prime. This should have a couple of large prime factors and hence be hard to factor, but notice it doesn't satisfy criterion 3 (since we can easily factor numbers ~10**100**2)

Does anyone have a better example?

My other instinct was Ramsey Numbers but these seem to fail criterion 1 since I didn't learn the definition in any high school math class.

Also thought of Collatz Conjecture which I guess would count if it had a counter-example < 10**100.
If I encounter a capabilities paper that kinda spooks me, what should I do with it?
by the gears to ascension — 2023-02-03T21:37:36.689Z

If I encounter a capabilities paper that kinda spooks me, what should I do with it? I'm inclined to share it as a draft post with some people I think should know about it. I have encountered such a paper, and I found it in a capabilities discussion group who will have no hesitation about using it to try to accumulate power for themselves, in denial about any negative effects it could have. It runs on individual computers.

edit for capabilities folks finding this later: it was a small potatoes individual paper again lol. but the approach is one I still think very promising.
What Are The Preconditions/Prerequisites for Asymptotic Analysis?
by DragonGod — 2023-02-03T21:26:48.987Z

Under what conditions is describing the behaviour of a (physical or abstract) process using asymptotic apparatus sensible/productive/reasonable?

Kinds of replies that I would find especially valuable:

Formal properties that a function (or collection thereof) must satisfy for applying asymptotic analysis to be sensible
Heuristics for when applying asymptotic analysis to real world processes is productive
Examples of real world processes satisfying the above
Examples of processes/functions that might seem amenable to asymptotic analysis but which it would actually be a mistake to try and consider through an asymptotic lens
[Linkpost] Google invested $300M in Anthropic in late 2022
by Orpheus16 — 2023-02-03T19:13:32.112Z
Link: https://www.ft.com/content/583ead66-467c-4bd5-84d0-ed5df7b5bf9c

A few quotes from the article:

Google has invested about $300mn in artificial intelligence start-up Anthropic, making it the latest tech giant to throw its money and computing power behind a new generation of companies trying to claim a place in the booming field of “generative AI”.

The terms of the deal, through which Google will take a stake of about 10 per cent, requires Anthropic to use the money to buy computing resources from the search company’s cloud computing division, said three people familiar with the arrangement.
The start-up had raised more than $700mn before Google’s investment, which was made in late 2022 but has not previously been reported. The company’s biggest investor is Alameda Research, the crypto hedge fund of FTX founder Sam Bankman-Fried, which put in $500mn before filing for bankruptcy last year. FTX’s bankruptcy estate has flagged Anthropic as an asset that may help creditors with recoveries.
Many AI governance proposals have a tradeoff between usefulness and feasibility
by Orpheus16 — 2023-02-03T18:49:44.431Z

Epistemic status: We think this is a simple and common idea in discussions about AI governance proposals. We don’t expect this to be controversial, but we think it might be useful to put a

label on it

and think about it explicitly.

Suppose an AGI lab could choose between two safety standards:

Standard 1: A third-party organization will implement intense auditing procedures every quarter. Training runs above a certain size will not be allowed unless the lab can show strong evidence in favor of safety.
Standard 2: Labs must have their own internal auditing procedures. There is a fair amount of flexibility in how the auditing should work. If a lab identifies something dangerous (as defined by the lab’s auditing team), they must report it to a third-party organization.

All else equal, people prefer restrictions that are less costly than restrictions that are more costly. Standard 2 is less demanding on labs, but it’s also less helpful in reducing x-risk.

Core point: There is often a tradeoff between the feasibility of a proposal (its likelihood of being implemented) and its usefulness (its expected impact on reducing x-risk, conditional on it being implemented).

We commonly observe this tradeoff in various conversations about AI governance. We don’t think this is a new idea, but sometimes

having a term for something helps us track the concept more clearly

.

We refer to this as the usefulness-feasibility tradeoff.

Additional points

Safety-washing. Measures that score highly on feasibility but low on usefulness might be examples of

safety-washing

. Ideally, we would try to put pressure on labs to raise their willingness to do things that are high on usefulness.
There are exceptions to the rule. The tradeoff doesn’t always apply, and there are some cases in which a proposal can score highly on both usefulness and feasibility. A potential example would be cybersecurity measures. At first glance, it seems valuable for labs to invest highly in cybersecurity (even if we model them as entirely self-interested) yet also useful for reducing x-risk.
Legible arguments for usefulness can improve feasibility. Labs are not entirely self-interested. Many lab decision-makers have expressed concerns around catastrophic risks. A proposal can be made more feasible if it is legibly useful for reducing x-risk. However,

Reply to Duncan Sabien on Strawmanning
by Zack_M_Davis — 2023-02-03T17:57:10.034Z

DAVID: [...] Because that's all we can ever have of each other: an imitation, a Copy. All we can ever know about are the portraits of each other inside our own skulls.

LORAINE: Is that all you think I am? An idea in your head?

DAVID: No! But if it's all I have, then it's all I can honestly love. Don't you see that?

And, miraculously, she does. She finally understands.

—"A Kidnapping" by Greg Egan

In the comments on "Basics of Rationalist Discourse" (where I am prohibited from commenting), Duncan Sabien writes, concerning my post "Aiming for Convergence Is Like Discouraging Betting", that it's "important to [him] that [I] be understood to not actually be responding to [him], rather than to [my] own strawman".

I don't think I understand the implied semantics of "actually" responding to an author. I don't consider myself any kind of authority on Sabien's views, and don't see myself as attempting to speak on his behalf.

Rather, I consider "Aiming for Convergence Is Like Discouraging Betting" to be responding to the published text of "Basics of Rationalist Discourse"—not Sabien's full private belief-state, which I obviously don't have access to. That is, I was attempting to use language to communicate some thoughts I had that were partially inspired by language that I read in "Basics of Rationalist Discourse".

Where I wasn't sure how to interpret the text because Sabien's thoughts and worldview differ so much from my own, I attempted to explicitly indicate my uncertainty, especially around the concepts of defection/cooperation and good/bad faith, of which I wrote (in the third summary bullet point) "I don't think I understand how these terms are being used in this context" and (in the body of the post) that the meanings "in my vocabulary" and "in my ontology" "don't seem consistent with the way Sabien seems to be using the words." I also included a paragraph "emphasiz[ing] [...] that this discussion is extrapolating a fair amount from the text that was written", and noting that Sabien might be using language differently from me "such that [my] objections don't apply".

It's quite possible that my reading comprehension of the post was poor, either "innocently" or "motivatedly". That is, it could be that a reader might compare my quotation or paraphrasing of "Basics of Rationalist Discourse" to the text of that post, and conclude that my construal of the text was unreas...
Semi-rare plain language words that are great to remember

I once spent a lot of time trying and failing to remember the word 'corollary', and once I heard it again I was like "ah, finally, there's that word; now I won't forget."

What are some other words like this? I'll keep an updating list in this post as I find and think of more of them.
