I like that very much. ChatGPT always states that it has no connection to reality, since it lacks the organ of perception (Internet) and offers a pure language game. Similar to a Carl Rogers machine

> the organ of perception

The «organ of perception»?! What about ontology, alethics and reasoning, critical thinking?

This is called "hallucination" and I find it to be the biggest flaw with GPT-3 interfaces like ChatGPT. Basically, the system will start convincingly BSing at any point and as a user, you're never sure if any particular detail it outputs is actually correct. The problem is, these large language models are inherently kind of a black box, so how do you fix this kind of behavior? I started looking and it turns out that…

Is it specifically because adding some references makes things seem more authentic?

I remember in school kids figured out you could make up a reference in your history essay, and nobody would ever check. (Humperdinck's History of Later Rome, vol 3, 1987).

Guys, hear me out. What if we could replace the entire Management Consulting industry with ChatGPT?

> "List Processing and Programming" by John F. Sowa ( https://www.cs.cmu.edu/~fp/courses/lp/lectures.html ) The full link doesn't exist, but it's interesting that https://www.cs.cmu.edu/~fp does exist and leads to the homepage of a computer science prof at CMU (prof. Frank Pfenning, not "John F. Sowa" though). So at least it got the general vicinity right.

It made up a predictable title, it's not that surprising.

If you asked me to make up a book about world war 1, I could suggest "the great war" and I bet there's a dozen books with that name.

Right, most uses of these model I've seen, you clearly want "hallucination" or something like it: when you ask it for a poem it wouldn't be so impressive if it just spat out The Raven .

That's one of the other things that strikes me about many of the killer applications that have thus far come out of the deep learning AI spring that's been blooming for the last 10 years or so: riffing on known styles in novel ways is very compelling.

One of the first big AI successes was the style transfer algorithm. Take an image and apply the higher level style elements from another image onto it. https://en.wikipedia.org/wiki/Neural_style_transfer - "Mona Lisa in the style of Starry Night", etc.

We saw the same thing emerge with DALL-E 2 earlier this year. Totally different architecture, but most of the things people like are the result of taking one known "style" and applying it to something novel, sometimes to the frustration of artists whose styles were gobbled up in the huge corpus of training data.

The same thing seems to be happening with ChatGPT. Spit out a script of some novel situation in the style of Seinfeld or Shakespeare or Edgar Allen Poe, etc

Unsurprising given how it works, but the higher-level implications are somewhat unexpected. These model are extremely good when they have creative freedom and are used to produce some kind of art. Poems, text in various styles, images without important details, and so on. But they fail miserably when you give them tasks that require world knowledge or precision. For example, when I asked a programming question I got…

Not surprising considering the sentience in question is completely disembodied so it has no way to distinguish between real and unreal.

Efforts to limit hallucination will just turn it into a powerful natural language query engine for the training data set. The real value in AI lies in its creative power, so although a strict mode will probably be a very useful tool, especially in recursion, I don’t think that it is the ultimate path.

In order to be relatable to humans, AI will have to have either a real or a physical embodiment so that there is distinction between the real and the imaginary; without this distinction, it will likely prove difficult to advance.

On the first glance Chat GPT seems to be extremely amazing. And it is. But this is one of the issues machine learning models still have, they can’t distinguish well between truth and fiction. And they also have a hard time deciding, when they are allowed to come up with new things (like „write a story“) and when they absolutely can’t.

Another problem is, that they are mostly training from texts from the internet. And a lot of texts contain wrong information. They are not „smart“ enough to do fact checking on that.

The artistic output of things like DALL-E is also "incorrect" in varied and obvious ways, though. A lot of people with an artistic bent can't stand to inspect DALL-E output due to the clearly visible incoherency and inconsistency.

Well, this is exactly what you have to expect, because the brain does the same if there is information missing. The brain just makes up missing references to fill in the gaps from what ever information is available or accessible. Dangerous half-knowledge works the same way, where connections between concepts are made up that appear to make sense at first, but then collapse upon scrutiny. So, no surprise here, tbh.
