I mean, everything is easy to predict in retrospect. :) Personally, I’m a bit surprised that it has learned any connection between the letters in the generated image and the prompt text at all. I had assumed (somewhat falsely it seems) that the gibberish means that the generator just thinks of text as a “pretty pattern” that it fills in without meaning. For example, a recent post on HN suggested that it likes the word “Bay”, simply because that appears so often on maps.
Yes, specifically a prompt about Thomas Bayes generated the caption "Bay of Tayees" and the theory was that "Bayes" got corrupted to "Bay of" because of maps.
I agree that this shows a focus on the appearance of the words rather than their meaning.

I like how psychology (or at least behavioural studies) is edging closer to being relevant in computer science.
In the spirit of that article, I wonder what DALL-E would spit out if you ask for "GilaWhamm" - probably images of scary medieval-looking men wielding scary medieval cutting weapons?
You could expect that gibberish is distributed uniformly in latent space, disconnected from it's langual counterpart -- after all those are textual inputs that model have never seen, and it can't even map words it have seen many times to their writing in image properly: "seafood" word and "seafood" image are in the same place in latent space, but "seafood" word in image isn't. Yet some gibberish word in image is, and also the same gibberish word is. It's very counterintuitive for me.
A uniform distribution makes sense for gibberish, not something I'd considered.
A counterpoint I'd raise is I wonder how aggressive Dall-E 2 is in making assumptions about words it hasn't seen before.
Hard to do given that it's read essentially the entire internet, however someone could make up some latin-esque words that people would be able to guess the meaning of.
If the model is as good as people at assuming the meaning of such made up words, it could stand to reason that if it were aggressive enough in this it might be doing the same thing with gibberish and thus ending up with it's own interpretation of the word, which would land it back in a more targeted concept space.
I'd love to see someone craft some words that most people could guess the meaning of, and see how Dall-E 2 fairs.

Prior art with GPT2: https://www.thisworddoesnotexist.com/
This might be considerably different, and calling it "prior art" fails to consider what is actually going on here. The appearance may be similar, but lots of things can look similar while being completely distinct. And this is indeed such a case.
One of the words I got was "charlite" for the pale green colour of charcoal used as a dye. Charlite might not be a real word, but it is made up the same way a real word would be.
The method is important, because "charlite" probably came about by specifically asking GPT2 for a definition to the non-word "charlite."
In fact, this shows up in the source code examples:
# definition for a word you make up print(word_generator.generate_definition("glooberyblipboop"))
This is literally the opposite of what OP is presented, since we know where the "defined" word comes from with the GPT2 examples, which means that was a demo of GPT2 trying to work out a human provided word. It is literally a function of the program: generate_definition(). It was specifically written to do that.
But we don't know where the words come from, even though they are internally consistent, with the DALL-E 2 examples. As far as we can tell, it's an internal phenomenon not based on intentional human input.
Having said that, GPT2 probably has the same phenomenon. But the link you provided is not demonstrating that.

ok, so proposed study design, provide a sample of these along with obscure english words to a number of individuals, and get them to try pick out the real words.
From there take the selection of the fake words people ranked the most real.
Select a number of those words and get Dall-E 2 to try and make images of them, then see how many of those images contain results that represent the imaginary word.
If anyone who has access to Dall-E 2 wants to try this, I would _love_ to see the results.

Apparently you can suggest prompts to their Instagram account.
Expected after the fact, somewhat. Before hand it would not be unreasonable to expect that the output text and the input text aren't necessarily that kind of connected, though, especially as as I understand it, DALL-E was not given input labelling explaining the text in various images. To it, text is just a frequently-recurring set of shapes that relate to each other a lot. This may yet be a false positive, based on other discussion.
That the model would have a consistent form of some kind of gibberish would be a given. Even humans have it: https://en.wikipedia.org/wiki/Bouba/kiki_effect And I'm sure if you asked native English speakers, "Hey, we know this isn't a word, but if it was a word, what would it be? 'Apoploe vesrreaitars'" you would get something very far from a uniformly random distribution of all nameable concepts.

In hindsight, sure. Given enough time someone might have predicted the phenomenon. But I don't think most of us did.
What's more fascinating to me is how often this has happened in this space in just the last few years.
1. Some phenomenon is discovered
2. I'm surprised
3. It makes sense in hindsight

Why? It could just go to noise images, or vaguely real-looking objects that don't look like anything in particular.

Are these algorithms even capable of generating noise images? And I don't mean asking them to generate "an image of tv static".
Of course this should be expected. The models are trained on internet data of natural language, where people are making typos, use abbreviations, some are not native speakers of english, others are talking in greeklish, or arabenglishy or whatever.
The machine is always trying to associate the words with other words semantically close together. E.g. when taken as input strong_man, or strng_man or srong_man these are all mean the same because that combination of letters are usually used with the word man, and there is no other competitor word to replace the srong except strong.
Now why that should be considered a secret language, it is beyond me. The input language for the machine is a natural human language, and that means it is very poor defined language for the machine to recognize. That is going always to produce a lot of gibberish.

Not really. It's a stochastic model, so after a bunch of random denoising steps, it could easily just be mapping every bit of gibberish to a random image, and it be vanishingly unlikely for any of them to be similar or the relationship to run in reverse.

This is really interesting because I was just looking at gibberish detection using GPT models. Seems like mitigating AI with AI doesn't sound like it's all that secure since you can probably mess with the gibberish detection similarly - Or maybe the 'secret language' as they're calling it here passes GPT gibberish detection?

No, it doesn't. The model in use maps all input to some output, but that isn't a necessary feature of the problem at all. It's actually a terrible idea.

I'm not sure it's a convincing rebuttal, the examples shown all seem to have some visible commonality.
Eg. "Apoploe vesrreaitais" Could refer to something along the lines of a "fan / wedge" or "wing-like"
If you look at the examples of cheese, when compared to the "birds and cheese" the cheese tends to be laid out in a fan like pattern and shaped in sharp angled wedges.

Yeah, and his example about bugs in the kitchen. Everything is edible and 'wild' or 'heirloom' and "contarra ccetnxniams luryca tanniounons" comes from the farmers talking about ... vegetables. So there's a definite interrelationship between the 'words' and the images.
I'm unconvinced by the rebuttal as well, not to say I am convinced we have a fully formal language going on here, but there's definitely some shared concepts with the generated text.
I wonder what imagen would come up with or if it's 'language' is more correlated to real language.

His counterexamples also have a flaw. He's expecting that mixing two languages have a consistent result given the human language meaning. Those words might have meaning in the DALLE language that totally flips the meaning of the whole phrase. Each batch of images is internally consistent.
I'm curious what it generates when given randomly generated strings of seemingly pronounceable words like "Fedlope Dipeioreitcus".
It seems to refer to "bird plant" which means birds on trees, so it would make sense there would be cheese and plants if it can't find how to fit a bird.

I don't think this is sufficient.
A language should have syntax and meaning. We can see these phrases (tokens?) have meaning.
It is unclear what they syntax is. But DALL-E2's idea of what the syntax is for English isn't how most people understand it either (as can be seen by how many rephrasing attempts people make to get what they want).
It's entirely possible (probable?) there is syntax here but we don't know it yet.

A rebuttal to the rebuttal (without examples)...
How many French people speak Breton?
How many French people speak Breton?
In short: DALLE-2 generates apparent gibberish for text in some circumstances, but feeding the gibberish back in gets recognized and you can tease out the meaning of words in this unknown language.
Is it gibberish in the true sense, or is it some sort of AI generated/learned latin text for the input models used? I wonder if they used a large number of biological images in their training data along with their scientific names, which led to this second order effect.
I think calling it gibberish is a misnomer, it would be gibberish if inconsistent, but if the same strings of characters lead to the same semantic objects then that is not gibberish.

I don't think it's a secret language per se. It's just that the tokens generated for these sentences are for some reason coming close to a bird latent space. Maybe if we can dig deep and do a google search for kinds of birds we can find the connection.

Serious question: what else do you think language is? How else would your brain associate the word "bird" with the concept?

I would associate a bird with a bird. I wouldn't associate birmongle with bird just because both start with the token "bir". What Dalle is doing here is what it has been trained to do. Just find the closest token match and try to draw something. It does not understand something. And that's absolutely fine. I am just saying it does not have a secret language or something. It's just regular language and it's closest matches.
But there's nothing particularly avian about the phonemes "bird". Your brain just matches that pattern of sounds to the nearest concept in thought-space, which happens to describe birds. That's what language is, a consistent mapping of words to concepts.
Which seems to also be what this article is describing.

I think the weird thing is that it creates these "words" and uses them in its output.
Indeed, this is an expected outcome from the way that DALL-E is trained. It’s still an interesting finding and sometimes affirming the expected can lay the groundwork for future interesting discoveries.
This is an example of an application where uncertainty modelling would help greatly. Any and every input will lead to an output. That doesn’t mean that all regions of latent/embedding space are equally valid.
I’m in the camp that large/modern ML models are nearing human intelligence, in some aspects. What’s currently missing is the universal ability to estimate uncertainty and identify inputs that are out of distribution. Many groups are working on this and perhaps we already have the solution but are not combining the right uncertainty estimation approach with the right foundational model.

Was DALL-E 2 trained on captions from multiple languages? If so, this makes a lot of sense. Somewhere early in the model the words "bird", "vogel", "oiseau" and "pájaro" have to be mapped to the same concept. And "Apoploe vesrreaitais" happens to map to the same concept. Or maybe "Apoploe vesrreaitais" is rather the tokenization of that concept, since it also appears in the output. So in a sense DALL-E is using an internal language to make sense of our world.
This looks like the artificial language Lojban was constructed: its words share parts from completely unrelated languages to the point when none of the original words are recognizable in the result.
The original words aren't recognizable at first glance, but they do serve as potential mnemonics for remembering the terms/definitions for any learners who speak one of those source languages (English, Spanish, Mandarin, Arabic, Russian, Hindi)
But that's expected behavior for a language model (especially VAEs), where's the novelty? In a VAE, the vectors are probabilistic in the latent space so this is basically the NLP version of the classic VAE facial image generation where you can tweak the parameters to emphasize or de-emphasize a feature.
Novel in engineering together of multiple concepts, if nothing else!

According to [1], the byte pair encoding for “Apoploe vesrreaitais” (the words producing bird images) is "apo, plo, e</w>, ,ve, sr, re, ait, ais</w>", and Apo-didae & Plo-ceidae are families of birds.

On the other hand the openai tokenizer gives me a different tokenization ap - opl - oe [0]. If you capitalize A the result is A - pop - loe. The dalle 2 paper only specifies that it uses a BPE encoding, I would assume they used the same one as for gpt3

If they use BPE dropout, then the split can be different and not unique.
And for the record, they use BPE dropout for DALLE-1, see https://arxiv.org/pdf/2102.12092.pdf

I believe they only apply it during training.
right, that is my point. It is hard to know which combination triggers the current tokenization to be interpreted as bird.

Which, to a lessor extent, isn't too terribly different from humans if you think about. We don't use a full new language but every profession has it's own jargon. Some of it spans the whole industry and some is company-specific.
Unintuitive to biased humans. The solutions may actually be super intuitive/efficient, and we just can't wrap our heads around it yet
It’s wild to see the discoveries being made in ML research. Like most of these ‘discoveries,’ it makes a fair amount of sense after thinking about it. Of course it’s not just going to spit out random noise for random input, it’s been trained to generate realistic looking images.
But I think it is an interesting discovery because I don’t think anyone could have predicted this.
One of my favorite examples is the classification model that will identify an apple with a sticker on it that says “pear” as a pear—it makes sense, but is still surprising when you first see it.

That classification model (CLIP) is the first stage of this image generator (DALLE) - and actually this shows that it doesn't think they're exactly the same thing, or at least that's not the full story, because DALL-E doesn't confuse the two.
However, other CLIP guided image generation models do like to start writing the prompt as text into the image if you push them too hard.

That's reminiscent of small children making up their own words for things. Those words are stable in that you can converse with the child using those words.
Wait, how does that make any sense?
I thought DALL-E's language model was tokenized, so it doesn't understand that eg "car" is made up of the letters 'c', 'a' and 'r'.
So how could the generated pictures contain letters that form words that are tokenized into DALL-E's internal "language"? Shouldn't we expect that feeding those words to the model would give the same result as feeding it random invented words?
Actually, now that I think about it, how does DALL-E react when given words made of completely random letters?

Wow, I am totally going to need to wait for more experimentation before believing any given thing here, but this seems like a big deal.
It's one thing if DALL-E 2 was trying to map words in the prompt to their letter sequences and failing because of BPEs; that shows an impressive amount of compositionality but it's still image-model territory. It's another if DALL-E 2 was trying to map the prompt to semantically meaningful content and then failing to finish converting that content to language because it's too small and diffusion is a poor fit for language generation. That makes for worse images but it says terrifying things about how much DALL-E 2 has understood the semantic structure of dialog in images, and how this is likely to change with scale. Normally I'd expect the physical representation to precede semantic understanding, not follow it!
That said I reiterate that a degree of skepticism seems warranted at this point.

Interestingly Google detects these words as Greek. I know they are nonsensical and not actually Greek but I'm wondering if any Greek speakers might be able to provide some insights. Are these gibberish words close to meaningful words? (clear shot in the dark here) Maybe a linguist could find more meaning?
As a native Greek, no, they don't make any sense.. sort of. My hunch is that they read significantly more like Latin than they do Greek. However it tells us something about google translate.
The reason "Apoploe vesrreaitais" is detected as Greek is because the first "word" is "phonetically" similar to the word απόπλους, which means sailing/shipping and it is rooted in ancient Greek. If we were to write Αποπλοuς using roman characters, we would write apoplous or apoloi (plural, in Greek is αποπλοΐ). So I think that the model understands that "oe" suffix is used to represent the Greek suffix "οι" that is used for plurals. The rest of the word is rather close phonetically, so there is some model that maps phonetic representations to the correct word.
The other phrase seems to be combined of words classified as Portuguese, Spanish, Lithuanian, and Luxembourgish.

This is a great response (I also suspected we'd learn something from the Google Translate black box). And I agree with the idea of being closer to Latin gibberish. The phonetic relationships are a great hint to what's actually going on.
My hypothesis here is more that these models are trained more on western languages than others and thus our latent representation of "language" is going to appear like Latin gibberish due to a combination of the evolution of these languages as well as human bias. ("It's all Greek to me")

I don't think that's how language detection works, they most likely use the frequencies of n-grams to detect language probability. It's still detected as Greek if you change to "Apoulon vesrreaitais", just because it kind of looks the way Greek words look, not because it resembles any specific word.
You are wrong. Had it been that simple I would __not__ have suggested that and for whatever reason I find your reply borderline infuriating but I can't pinpoint exactly why that is.
Regardless, here is me, a native speaker, disproving your hypothesis.
I tried the following words in google translate elefantas ailaifantas ailaiphantas elaiphandas elaiphandac.
The suggested detections are ελέφαντας, αιλαιφάντας, αιλαιφάντας, ελαϊφάντας, ελαϊφάντας, however, the translations are elephant, illuminated, illuminated, elephant, elephant respectively. The first is correct. When mapping the roman characters back to greek, there is loss of information, this is seen in the umlaut above iota which makes the pronunciation from ε [e] - like to αϊ [ai̯], and the emphasis denoted via the mark above epsilon (έ).
Notice that all all the words have an edit distance of >=4, a soundex distance of at most 1, and a metaphone distance of at most 1 [1]. The suggested words as I said above are near homophones of the correct word bar a few minor details.

Regardless, here is me, a native speaker, disproving your hypothesis.
I tried the following words in google translate elefantas ailaifantas ailaiphantas elaiphandas elaiphandac.
The suggested detections are ελέφαντας, αιλαιφάντας, αιλαιφάντας, ελαϊφάντας, ελαϊφάντας, however, the translations are elephant, illuminated, illuminated, elephant, elephant respectively. The first is correct.

> for whatever reason I find your reply borderline infuriating but I can't pinpoint exactly why that is.
I guess that says more about you than about my reply. Also, I'm a native speaker as well. That doesn't really have any bearing, my comment above comes from what I know about common implementations of language detection algorithms, not so much from looking at how Google Translate behaves.

And I was honest about how I felt given how you structured it.
It does have a lot of bearing actually. While I am a native speaker, my spelling skills are atrocious as everything is a sequence of sounds in my head more so than a sequence of letters. To get around my spelling issues I frequently use homophones to find the correct spelling of a word which uses soundex or similar algorithms to find the correct word along with character mappings between the two languages.
Regardless, I believe I have proved the hypothesis to not be true.

One could conjecture that "Apoploe" is similar to από πουλί, "from bird". But I don't have much support for that conjecture.
The word is απόπλους, or αποπλοΐ
For some reason this comment from someone else was deleted:
"My first reaction to this was, "It probably has to do with tokenization. If there's a 'language' buried in here, its native alphabet is GPT-3 tokens, and the text we see is a concatenation of how it thinks those tokens map to Unicode text." Most randomly concatenated pairs of tokens simply do not occur in any training text, because their translation to Unicode doesn't correspond to any real word. There are also combinations that do correspond to real words ("pres" + "ident" + "ial") but still never occur in training because some other tokenization is preferred to represent the same string ("president" + "ial").
Maybe DALL-E 2 is assigning some sort of isolated (as in, no bound morphemes) meaning to tokens — e.g., combinations of letters that are statistically likely to mean "bird" in some language when more letters are revealed. When a group of such tokens are combined, you get a word that's more "birdlike" than the word "bird" could ever be, because it's composed exclusively of tokens that mean "bird": tokens that, unlike "bird" itself, never describe non-birds (e.g., a Pontiac Firebird). The exact tokens it uses to achieve this aren't directly accessible to us, because all we get is poorly rendered roman text."
I wonder if this is why the term for "bird" seemed to be in faux binomial nomenclature, the scientific names for animals. I assume that in the training set there were images of birds/insects with their scientific name. An image labeled with the scientific name would always be an image of an animal, unlike images with the word bird in them which could be of a birdhouse, Pontiac Firebird, or someone playing golf. That would mean that in the latent space when DALLE wants to represent a bird as accurately as possible, it will use the scientific name, or a gibberish/tokenized version of the scientific name-- like someone trying to make up a name that sounds regal might say "Sir Reginard Swellington III". Even though it's not a real name it encodes into the latent space of royal-sounding names.
I wonder if this could be extended to other things with very specific naming conventions. For example aircraft names: "Gruoeing B-26 Froovet" might encode into military aircraft latent space.

It seems obvious this would happen (it's just adversarial inputs again) - they didn't make DALL-E reject "nonsense" prompts, so it doesn't try to, and indeed there's no reason you'd want to make it do that.
Seems like a useful enhancement would be to invert the text and image prior stages, so it'd be able to explain what it thinks your prompt meant along with making images of it.

Interesting! I wonder if the model would "understand" the made-up names from today's stained glass window post[1] like "Oila Whamm" for William Ockham and output similar images.

My first thought upon reading this: what if DALL-E (or a similar AI) uncovers some kind of hidden universal language that is somehow more "optimal" than any existing language?
i.e. anything can be completely described in a more succinct manner than any current spoken language.
Or maybe some kind of universal language that naturally occurs and any semi-intelligence life can understand it.
Fun stuff!

This is kind of already what's happening inside the NN. You can think of intermediate layers in the network as talking to each other in "NN-ease", that is, translating from one form of representation (encoding) to another. At the final encoder layer, the input is maximally compressed (for that given dataset/model architecture/training regime). The picture (millions of pixels) of the dog is reduced to a few bits of information about what kind of dog it is and how it's posed, what color the background is, etc.
However, optimality of encoding is entirely relative to the decoding scheme used and your purposes. Obviously a matrix of numbers representing a summary of a paragraph can be in some sense "more compressed" than the English equivalent, but it's useless if you don't speak matrices. Similarly, you could invent an encoding scheme with Latin characters that is more compressed than English, but it's again useless if you don't know it or want to take the time to learn it. If we wanted we could make English more regular and easier to learn/compress, but we don't, for a whole bunch of practical/real life reasons. There's no free lunch in information theory. You always have to keep the decoder/reader in mind.

Ithkuil (Ithkuil: Iţkuîl) is an experimental constructed language created by John Quijada.[1] It is designed to express more profound levels of human cognition briefly yet overtly and clearly, particularly about human categorization.
Meaningful phrases or sentences can usually be expressed in Ithkuil with fewer linguistic units than natural languages.[2] For example, the two-word Ithkuil sentence "Tram-mļöi hhâsmařpţuktôx" can be translated into English as "On the contrary, I think it may turn out that this rugged mountain range trails off at some point."[2]

That’s not possible - it’s like asking for a compression system that can compress any message.
All human languages are about the same efficiency when spoken, but of course this mainly depends on having short enough words for the most common concepts in the specific thing you’re talking about.
https://www.science.org/content/article/human-speech-may-hav...
And there can’t be a universal language because the symbols (words) used are completely arbitrary even if the grammar has universal concepts.

There are a couple sci-fi short stories in the book "Stories of Your Life and Others" by Ted Chiang which explore the idea that highly advanced intelligences might create special languages which accommodate special thoughts which we cannot easily think.
I think something like this is actually quite likely.
I’ve been wondering if there is a way to do psychological experiments on these large language models that we couldn’t do with a person.

I imagine these would be very interesting, but not very applicable to humans (which I presume is the intended outcome). OTOH, since these language models are trained on human language and media, they might have some value. I'm quite split on which I think is more likely (I don't have any experience in ai/ml nor in psychology so what do I know).
One example of an ’experiment’ would be to explore the latent space with random/procedurally generated prompts and do semantic analysis on the results to look for topics or sentiments to emerge.
My guess is that the current language models don’t have enough information in the training data to do this usefully today, but over time it seems potentially viable.

This one melts my brain a bit, I’m not going to lie. Whales talking about food, with subtitles. “Translate” the subtitles and you get food that whales would actually eat.

I'm seeing a lot more people experimenting with DALL-E 2.
How does getting access work, do you need a referral?

Would it be possible to build a rosetta stone for this secret language with prompts asking for labeled pictures of different categories of objects? Or prompts about teaching kids different words?
I find it really interesting how these new large models (DALLE, GPT3, PaLM etc) are opening up new research areas that do not require the same massive resources required to actually train the models.
This may act as a counter balance to the trends of the last few years of all major research becoming concentrated in a few tech companies.

What if give it the same promt but "with subtitles in French" for example?
If I understand correctly from the twitter thread (I haven't read the linked
technical report) the author and a collaborator found that DALL-E generated some
gibberish in an image that showed two men talking, one holding two ... cabbages?
They fed (some of) the gibberish back to DALL-E and it generated images of
birds, pecking at things.
Conclusion: the gibberish is the expression for birds eating things in DALL-E's secret language.
But, wait. Why is the same gibberish in the first image, that has the two men and the cabbages(?), but no birds?
Explanation: the two men are clearly talking about birds:
>> We then feed the words: "Apoploe vesrreaitars" and we get birds. It seems that the farmers are talking about birds, messing with their vegetables!
With apologies to my two compatriots, but that is circular thinking to make my head spin. I'm reminded of nothing else as much as the scene in the Knights of the Round Table where the wise Sir Bedivere explains why witches are made of wood:

I wonder if any linguists are training a neural network to generate Esperanto 2.0.
I tried a few of these in one of the available CLIP-guided diffusion notebooks, but wasn't able to get anything that looks like DALL-E meanings. Not sure if DALL-E retrained CLIP (I don't think they did?), but it maybe suggests that whatever weirdness is going on here is on the decoder side?
All the cool images that DALL-E spits out are fun to look at, but this sort of thing is an even more interesting experiment in my book. I've been patiently sitting on the waitlist for access, but I can't wait to play around with it.

I love this scientific curiosity towards DALL-E. Many people just say that it's bad at text generation (including me), but someone stopped to wonder if this is really gibberish or it has some logic to it. Classic "hmm, that's odd" case.
It will be fun to see people experimenting with extracting text prompts from generated images. I'd try something like "An open children book about animals" or "Random thought written on a paper". Maybe do a feedback loop of extracted prompts :)

A few days ago I was wondering what DALL-E would generate if given gibberish (tried to request which wasn't entertained). This sounds like an answer to that to some extent.
I think, there will be multiple words for the same thing. Also, unlike 'bird' the word 'Apoploe vesrreaitais' might actually mean specific kind of bird in specific setting.

I love the weird edge cases of ML. Imagine discussing security concerns and saying "what if it creates it's own secret language that we don't know about, which is discovered later, and people can use to circumvent privacy and obscenity controls?"

Gibberish has to map _somewhere_ in the models concept space.
Whether is maps onto anything we'd recognise as consistent doesn't mean that the AI wouldn't have some concept of where it relates, as other people have noted, the gibberish breaks down when you move it into another context, but who's to say that Dall-E 2 isn't remaining consistent to some concept it understands that isn't immediately recognisable to us.
The interesting part is if you can trick it to spit out gibberish in targeted areas of that concept space using crafted queries.
